Barrettine Environmental Health has launched MiteMax, a new treatment for poultry red mite (PRM) with a physical mode of action.
Charles Phillips from Barratine said: "PRM poses a significant threat to laying hens particularly, with infestation costing the UK egg industry in excess of an estimated €3 million per annum through PRM control and lost production. In the UK, PRM is prevalent in varying percentages according to the rearing system used. Caged birds are estimated to have a variable 7.5 to 87.5 % prevalence. Free range systems are estimated to have 60 % prevalence of PRM, with organic systems higher at 78 %. Less intensive systems have a greater prevalence of PRM due to the higher number of cracks and crevices associated with a more enriched environment1."
MiteMax is applied directly to a shed’s inner surfaces via knapsack sprayer, rendering the surfaces sticky and permanently immobilising red mites that come into contact with them.
According to the company, the new product - which is designed to fit into and encourage integrated pest management practices - provides rapid knock-down of poultry red mite.
Charles added: "The physical mode of action of MiteMax makes it effective against pesticide-resistant mites. MiteMax is specifically formulated to penetrate surface dust making it highly effective at reaching mites harbouring deep in crevices."
In conjunction with robust cleansing practices, Ian Whelan an expert in physical insect control techniques says MiteMax fits neatly into an integrated pest management style of husbandry: "Using treatments with different modes of action together as part of a flock health plan ensures each one fulfils its potential."
MiteMax is available nationwide from Barrettine Environmental Health's appointed distributors.

The RCVS has brought out a new publication to help members of the veterinary and veterinary nursing professions understand their legal and professional obligations regarding controlled drugs.
Controlled Drugs Guidance is a consolidation of existing advice and guidance on controlled drugs from a number of organisations including the RCVS itself, the Veterinary Medicines Directorate (VMD), the British Small Animal Veterinary Association (BSAVA) and the Home Office. The guide also gives details of the existing legislation concerning controlled drugs, namely the Misuse of Drugs Act and associated regulations.
The guidance provides advice on a variety of topics to reflect the common queries the RCVS Advice Team receives, such as storage, destruction and disposal; keys and keyholders for controlled drugs cabinets; controlled drugs in vehicles; and veterinary nurses administering controlled drugs.
The publication also deals with specific controlled drugs such as ketamine which, on 30 November 2015, was rescheduled to a Schedule 2 controlled drug, meaning that it is now subject to the same strict storage, prescription, dispending, destruction and record-keeping requirements as other medicines in this Schedule.
Laura McClintock, Standards and Advisory Manager at the RCVS, said: “We hope that this publication will help members of the profession navigate the often complex legislative and professional requirements regarding controlled drugs, as well as imparting best practice advice on how they should be stored and disposed and so on.
"This publication has also been endorsed by our colleagues in the Home Office, VMD and BSAVA and, because this is an area that is subject to regular change, we will make sure to keep it up-to-date as and when the regulations change."
The publication is available to download from the RCVS website at www.rcvs.org.uk/publications
IDT Biologika and Hysolv Animal Health have announced the publication of A guide to oedema disease in pigs, a six-page booklet written to help pig producers understand the causes, effects and treatment of this ailment.
Author, F Javier Salquero, an independent European veterinary specialist in porcine health management, outlines the risk factors, how to identify oedema disease, current methods of treatment and prevention strategies. The booklet includes a table of the symptoms to be expected in new-born, suckling, post-weaned, grower-finishers and adult pigs.
The booklet concludes that treatment of oedema disease is generally unsuccessful and most pigs showing clinical signs die. However, preventive measures include adjustment of feeding regimes, stress reduction, improved biosecurity and vaccination.
Hysolv director, Richard Brealey said: "Oedema is a widespread, lethal and economically-important disease in pigs, and there is increasing pressure in Europe to reduce the use of antibiotics in livestock. Fully understanding this disease is a first step to control and prevention".
Hysolv says a German calculation showed a reduction in margin of 83 Euros (£74) per sow, equivalent to 41,000 Euros (£32,500) for a 500-sow herd, due to oedema.
The booklet — printed on heavy duty glossy card – suitable for use in piggeries — is available, free, by visiting the Hysolv website: www.hysolv.co.uk
Two new campaigns which call on the veterinary profession to unite against the practice of homeopathy have been launched this week.
Both campaigns raise concerns about the ethics of veterinary surgeons using irrational, unscientific and ineffective remedies to treat ill animals or in place of conventional vaccinations.
The Campaign For Rational Veterinary Medicine presents the case against homeopathy on a new microsite, and asks the profession to unite around a call for the Royal College of Veterinary Surgeons to issue a public position statement that homeopathy is ineffective in animals, bringing it into line with the NHS, the findings of the British government's own review of homeopathy, and the BVA.
The campaign also asks that veterinary surgeons who prescribe homeopathic remedies be required to get owners to sign a consent form, prepared by the College, giving the College’s views on the ineffectiveness of homeopathy.
Lastly, the campaign asks that promotion or advertising of homeopathy by veterinary surgeons should abide by Advertising Standards Authority regulations and carry a statement from the College.
The Campaign for Rational Veterinary Medicine has been set up by a group of practitioners including the BSAVA Past President, Mike Jessop, Alex Gough, Martin Whitehead, Niall Taylor, Phil Hyde, Martin Atkinson and Brennen McKenzie, supported by VetSurgeon.org Editor, Arlo Guthrie. It also has the support of the noted author, academic and erstwhile dog owner, Professor Edzard Ernst.
Arlo said: "This is not just about the ethics of prescribing or tolerating the practice of prescribing water to animals that are dependent on us. There are 13m pet owning households in the UK. As well as visiting the vet, they will all be patients at some stage in their lives. So what you and the College say about homeopathy in animals has the potential to affect the choices they make for themselves too. Think how much money and false hope you could save them, and the consequent benefit to human welfare."
By complete coincidence, another campaign against veterinary homeopathy was launched last week. This one, by Danny Chambers MRCVS goes further, calling for a complete ban on the prescription of homeopathic remedies by veterinary surgeons. The petition has already gathered over 750 supporters.
Arlo said: "I think it’s important to say that the two petitions are not mutually exclusive. If you think both represent acceptable solutions, then sign both!"

Dr Johanna Fink-Gremmels – Professor of Veterinary Pharmacology and Toxicology at Utrecht University – has warned that UK cattle producers need to plan for an on-going struggle with feed-borne mycotoxins, and says vets need to help farmers understand and mitigate the negative impact on animal health.
Speaking to cattle vets at a CPD meeting organised by Alltech, she said: "When you see a general inflammatory response, such as elevated somatic cell count, mycotoxicosis should always be on your radar. The mycotoxin threat to cattle is increasing in the UK, yet it is often the most neglected causative issue on any list of pathogenic suspects."
Johanna explained that natural toxins produced by diverse fungal species are proliferating worldwide, partly as a result of global climate change, but also because of changing agronomic practices in developed countries.
"Total mixed rations often now contain more than one fungal species, contributing to a complex mycotoxin picture and unresolved health issues in a herd as a result. Cow signals such as reduced feed intake, reproductive disorders, laminitis, mastitis, impaired liver function, a poor response to vaccination programmes and even increased susceptibility to bacterial and viral diseases can all be attributed to ingesting mycotoxin contaminated feed."
Johanna says the biggest challenge for UK dairy farmers is now multiple mycotoxin contamination of grass and maize silage.
"Cattle health problems with feeding obviously mouldy silage are relatively well understood. But new harder to detect fusarium toxins – such as, for example, Enniatins and Beauvericin contaminating cereal grains – are also now being found in pasture grass in Northern Europe. These will also adversely affect the efficiency and function of the rumen.
"The rumen determines the health and productivity of the cow. When rumen bacteria are suffering the liver does not function correctly initiating a cascade of adverse events; and often a generalised inflammatory response is triggered, which leads to a loss of production."
Johanna added that in the future farmers will need select feed crop plants that are more resistant to fungal invasion and will also have to re-adjust tillage methods to reduce mould contamination. "However, we know that this alone will not stamp out mycotoxin contamination without creating a biological vacuum that will be filled with other micro-organisms.
"Consequently, it will be essential to continue to apply strategies such as rigorous on-farm risk assessment and the use of appropriate in-feed mycotoxin-sequestration agents (binders) to prevent the production-limiting and adverse health effects in our farmed livestock."
Leading human and animal health organisations – the British Medical Association (BMA), British Dental Association (BDA), British Veterinary Association (BVA) and Royal Pharmaceutical Society (RPS) - have joined forces for the first time to promote a ‘One Health’ approach to ensure responsible guardianship of antibiotics and their proper public use on European Antibiotics Awareness Day tomorrow.
Antibiotics are obviously a vital medicine for both animal and human health, and modern health systems rely on the availability and effectiveness of a range of antimicrobials to treat and prevent infections. Yet inappropriate use – such as prescribing for self-limiting infections, not finishing a prescribed course of antibiotics or habitual prophylactic use in healthy animals to prevent disease - all contribute to the development of resistant bacteria in both humans and animals.
Whilst antibiotic resistance in animals does not perhaps present the greatest immediate existential threat, there is a strong argument for a united message to the public coming from doctors, dentists, chemists and veterinary surgeons.
Quite simply, some 13M households own a pet. Pretty much all of them visit a vet at some stage, and most will be a human patient at some point in their lives. So, what a veterinary surgeon says about the use of antibiotics in animals has the potential to help transform how owners think about them when they come to visit the doctor.
A survey of general practitioner doctors last year found that 90% feel pressured by patients to prescribe antibiotics and 28% have prescribed them several times a week when not sure they are medically necessary. If veterinary surgeons refuse to prescribe them for pets unless medically necessary, explaining that they are a precious resource which can no longer be wasted, it could help relieve the pressure on doctors. The same goes for the importance of compliance; if owners learn the importance of their pet taking the full course, there's a greater chance they'll understand why they need to complete their own course of treatment.
BVA President Sean Wensley said: "Antimicrobial resistance (AMR) is too important an issue for uncoordinated approaches amongst the medical professions. We need to work together to share knowledge and successful approaches, as well as taking responsibility for not just the immediate clinical situations before us, but also for our role in supporting the health and wellbeing of wider society. An effective approach to tackling AMR is about professions and patients working together for the greater good."
BMA board of science Chair Professor Sheila the Baroness Hollins said: "Doctors have expressed significant concern about the threat of a ‘post-antimicrobial age’. It is vital that we see action to improve antimicrobial prescribing across all disciplines. Only by different professionals working together to improve antimicrobial stewardship will we start to address this major public health issue."
BDA President Professor Nairn Wilson said: "All health professionals have a responsibility to draw a line under inappropriate or unnecessary use of antibiotics. One in ten prescriptions in the UK are provided by dentists, so we’re determined to do our bit. We are facing a clear and present danger to public health, and it will only be overcome if we act together."

To mark EAAD 2015, BVA has produced a range of new posters to promote the responsible use of antibiotics for use in veterinary practices or as a source of information for pet owners which can be found on their website www.bva.co.uk/eaad.
The Westpoint Group has announced the divestiture of its small animal and equine veterinary practices in order to focus on production animal health and welfare.
From now, the production animal business - which includes veterinary practices providing services to pig, poultry, dairy, beef, sheep, game bird producers and small holders - will be known under the umbrella brand of Origin.
The company says that excellence and innovation in client service will continue to be the focus throughout the organisation.
Matt Dobbs, Managing Director of Origin said: "Origin is committed to supporting livestock farmers to enhance production by improving health and welfare. We have a unique group of vets, researchers, lab techs and paraprofessionals passionate about the success of UK agriculture, with other businesses committed to supporting the industry, joining us through the autumn.
"By focusing on supporting farmers, we will become a unique source of animal insight in livestock agriculture."

The industry-led Cattle Health and Welfare Group of Great Britain (CHAWG) has published a review which identifies a practical approach to gathering antibiotic usage data on UK cattle farms.
The review outcomes, announced today at a joint conference held by the Responsible Use of Medicines in Agriculture Alliance (RUMA) and the Veterinary Medicines Directorate (VMD), highlight the significant benefits better data could deliver, such as improving the way antibiotics are administered strategically to tackle disease.
But CHAWG’s chair Tim Brigstocke says it’s also important that the industry is able to accurately report usage levels because of the rising levels of antibiotic-resistant bacteria which threaten human health.
"We found that while data is already stored at every vet practice and in every farm medicine book, it currently exists in many different forms. It’s also not collected or collated, and is further complicated by multi-species approvals for many of the antibiotics.
"This means we can’t always be sure in which type of animal a medicine has been used. For example, out of 420 tonnes of animal-authorised antibiotic active substance sold in the UK in 2013, only 14 tonnes was authorised solely for use in cattle. However, 63 tonnes was authorised for multi-species use in food producing animals and within the 217 products included in this, 201 are authorised for use in cattle."
Tim says that with the support of the VMD, which requested the review and will now act as secretariat, CHAWG will set up a working group to implement the report’s recommendations.
The starting point is likely to be the survey of vets carried out by the British Cattle Veterinary Association (BCVA), which formed part of the review. This suggested vets could be using as many as 15 different software programmes to log data, so CHAWG will be working with the BCVA and individual practices to look at how standard sets of data can be anonymised and exported.
"Then we will almost certainly look at how cattle farmers can be supported in migrating records from the physical ‘medicine book’ on the farm, into a spreadsheet or existing cattle management software for anonymous aggregation on a national level.
"There are undoubtedly areas where we can improve the effectiveness of how we use these powerful medicines to improve welfare. But the antibiotic resistance debate is an emotive one and we must also demonstrate accountability to ensure the preservation of antibiotics for future use in humans and animals; any future curbs on usage should be proportionate and informed, and not compromise animal wellbeing."
Mandatory reporting in Europe could be just over the horizon and the European Medicines Agency has focused in the past year on developing a method for data collection on the usage of antibiotics in the EU pig sector. In the UK, the VMD is encouraging the livestock sectors to develop systems appropriate to their own unique circumstances and industry characteristics.
Tim said: "It’s therefore in cattle farmers’ own interests to anticipate the kind of figures it might be asked to supply in the future, and develop a way of collecting that data which suits the way the UK industry works.
"Then we can retain control over the data and the methodology, and ensure the reporting is accurate – and this in turn will help the VMD represent our case better in Europe as this debate continues.
CHAWG says that throughout this project, it will be liaising with others – such as the pig sector – to ensure learnings are shared, duplication avoided and efficiencies realised where possible.
The CHAWG review report is available to download at www.chawg.org.uk.
The National Office of Animal Health has issued a statement criticising the All Party Parliamentary Group on Antibiotics report: "Non-human uses of antibiotics: time to restrict their use?”, saying it fails to recognise the steps that have already been taken by vets and farmers to prevent disease and minimise antibiotic use on farms where possible.
NOAH chief executive Dawn Howard said: "NOAH fully supports the need for responsible prescribing, by both the veterinary and medical professions.
"On the veterinary side, NOAH has been very actively involved with responsible use initiatives, such as the RUMA Alliance, which publishes guidelines supporting responsible use and has produced an action plan on livestock antibiotic resistance to implement Government strategy.“
NOAH highlights two particular aspects of the report. Firstly that it is critical of the treatment of groups of animals through medicated feed and water.
Dawn said: "There are many animal-friendly reasons why medicines can be prescribed in this way by a veterinary surgeon.
"For groups of animals, fish or birds there is less stress than injection or individual oral dosing. Where treatment is needed, the vet supplies a prescription for treatment through medicated feed or through the water, depending on the product being used. The whole process is highly regulated through European and national legislation."
The report also suggests certain classes of antibiotics should be reserved for humans. NOAH says it believes that veterinary surgeons need to retain the full range of currently licensed antibiotics in order to be able to treat the range of conditions that affect animals, and if they are restricted, animal welfare will undoubtedly suffer.
NOAH adds that removal of some classes from the veterinary sector would place undue selective pressure on the remaining classes which could increase resistance to those classes – having the opposite effect to what the committee probably intends.
Dawn said: “NOAH is disappointed not to have been consulted in advance of the publication of the report. We believe that responsible use of veterinary antibiotics is the best way to help preserve these precious medicines for us all, without compromising the health and welfare of our animals.”

The Society of Practising Veterinary Surgeons (SPVS) is putting out a last call to take part in the SPVS Salaries Survey 2015, open to everybody working in the veterinary profession.
The long-standing survey provides a benchmark for veterinary surgeons, nurses and support staff to see trends in pay and conditions. Designed to provide a complete picture of remuneration levels, the survey covers basic earnings, bonuses, dividends, overtime and benefits such as accommodation, car allowances, private medical insurance and pensions. It also includes questions on employment contracts, hours worked, out of hours and weekend working.
Peter Brown, SPVS Treasurer and author of the Salaries Survey said: “I have been compiling the survey results for a number of years but it never fails to enlighten me as to what is happening in the profession. I know it is also the go to reference guide when practices are recruiting to help ensure they are offering competitive salary packages.
“Participation in the survey is open to all and the more practices that take part, the more accurate and useful the information will be so we would urge everyone working in the veterinary profession to take a few minutes to complete the survey. It can be done online and the information is completely anonymous.”
To complete the survey online, visit www.spvs.org.uk or, for a printed version, telephone 01926 410545. The survey is open until 30 November 2015.
Virbac has announced that its recently launched parasiticide Neoprinil has been granted a shelf life extension from one to two years after first opening.
The company says the extension will help minimise the risk of wasted product and increase its convenience to farmers.
An eprinomectin pour-on solution, Neoprinil is indicated for use against internal and external parasites in cattle, including gut and lungworms, mange mites, sucking and chewing lice, horn flies and warbles. It is administered using the company's Farmpack and Flexibag, and offers a zero-day withdrawal period in milk.
Virbac's Product Manager for Large Animals Brigitte Goasduf MRCVS said: "Understanding the challenges our customers face and offering products to overcome them is our goal so we are delighted that Neoprinil has received a shelf life extension because this adds to its flexibility and convenience for farmers. It also brings it into line with Deltanil, our deltamethrin-based pour-on for use against a range of ectoparasites in cattle and sheep.
"We now offer a comprehensive and flexible parasiticide range administered with a dispensing system that sets a new standard for convenience and ease of use."
Neoprinil is presented in 2.5l, 4.5l and 8l pack sizes.
Hysolv Animal Health has announced that it is offering a free swine flu laboratory diagnostic service to veterinary surgeons in the UK and Ireland.
The company will supply kits to veterinary surgeons with which to take samples from pig herds they suspect are infected with swine flu. The samples, nasal swabs or blood, will be sent direct to Germany where vaccine and biological company IDT Biologika is using a special facility to detect which viruses or antibodies against certain serotypes are present.
The virological tests will be conducted by the Institute for Virus Diagnostics, part of the Federal Research Institute for Animal Health. Antibody titres against H1N1, H1N2, H3N2, panH1N1 and panH1N2 will be looked for. Hysolv says these tests, including histopathology, can provide the only conclusive proof of influenza infection.
Results from the test — which would normally cost 230 Euros (about £185) to conduct — will be available within a week. IDT is believed to be the first company offering this type of test.
According to the company, the PCR test — from nasal swabs — is much more precise than previous testing regimes and will identify and type circulating strains as well as emerging strains.
Hysolv says that when swine flu strikes a farm, the signs seen are no longer just typically flu-like but a show whole range including fever, coughing, dyspnoea as well as returns to oestrus and abortions in sows. These may be in combination and concurrent with other diseases which makes accurate diagnosis difficult.
IDT will be offering the newly-branded vaccine Respiporc Flu 3 where the veterinary surgeon feels vaccination in indicated.
Hysolv director Richard Brealey said: “IDT is raising the bar in flu testing and this is a significant advance on what has been done in the past. In 2014 one-third of 1353 nasal swabs sent for testing proved positive for swine flu in Germany. In the UK the samples will help give an insight into the epidemiological status quo of the national pig herd.”
Zoetis has released new surveillance results which show that Mycoplasma bovis is becoming an increasingly significant pneumonia pathogen in cattle1.
In more than 2,500 samples submitted by vets for analysis during 2014, 45% were positive, compared with 41% in 2013.
According to Dr Tim Potter MRCVS from Westpoint Veterinary Group, Mycoplasma bovis has emerged as an important pathogen of calves worldwide2. He said: "It is associated with a number of clinical presentations including respiratory disease, otitis media and arthritis.
"The role of Mycoplasma bovis in pneumonia is well established and there are a number of reports in the literature of respiratory disease outbreaks where it was the predominant bacterium isolated. However, as with most causes of pneumonia, colonisation by Mycoplasma bovis alone is not always sufficient to cause disease and it may present in combination with other respiratory pathogens."
For other pathogens, the surveillance found 83% of samples positive for Para-influenza 3 virus (Pi3v), 76% Bovine Respiratory Syncytial virus (BRSv), 32% IBR, and 25% for BVD. Apart from BVD, which saw a three-point reduction from 28% the previous year - these show little change from 2013.
According to Zoetis vet Carolyn Hogan, in pneumonia outbreaks involving Mycoplasma bovis, many of the clinical signs are similar to those caused by other pneumonia pathogens: coughing, raised temperature, rapid breathing and lethargy.
She said: "This can make it difficult for farmers and vets alike to identify Mycoplasma bovis as a possible cause of disease based on clinical signs alone, unless calves are also showing some of the other distinguishing signs associated with Mycoplasma infection.
"These include ear infections, head shaking or tilting, and arthritis. Poor response to treatment, with resulting chronic respiratory cases, may also be suggestive of Mycoplasma infection. For a definitive diagnosis, of course, analysis of blood or respiratory tract mucous is required."
Whilst vaccination protection is available against the viruses (BRSv, Pi3v, BVD and IBR) and Mannheimia (Pasteurella) haemolytica, Carolyn points out that there is no ‘off the shelf’ vaccine available for Mycoplasma bovis. She adds that treatment can be challenging due to the insidious nature of disease, and lack of effectiveness of some antibiotics.
Once Mycoplasma bovis is present on a farm, Carolyn cautions that eradication can be very difficult. "It can be transmitted in milk from carrier cows, and in saliva among calves, particularly when multiple animals suckle the same teat feeders.
"Minimising this pathogen's impact on health and productivity relies on reducing its exposure to susceptible animals and maximising their resilience against it. For a comprehensive programme of control measures, farmers should consult their vet."
Carolyn suggests that such a programme is likely to include: testing the farm's Mycoplasma bovis status; effective biosecurity; not feeding infected milk; ample ventilation for adults and youngstock alike; rapid spotting of sick animals, isolation and vet-prescribed treatment; vigilance for poor response to treatment and development of chronic cases; vaccination against main viral pneumonia pathogens; and low stress through good stockmanship.

Merial has published figures which show that gutworm is seriously affecting dairy cow fertility in up to 80% of UK dairy herds1, in order to raise awareness of the damaging impact of Ostertagia ostertagi.
Sioned Timothy, veterinary adviser for Merial said: “The reduction in milk production from a gutworm infection is well documented2. Both animal health advisers (Suitably Qualified Persons – SQPs) and vets recognise the threat such infections cause. However, since cows often show no outward signs of disease, even in the face of a massive challenge, dairy farmers could unwittingly suffer heavy losses in milk yield, reduced fertility and increased heifer rearing costs at a time when they can least afford it.”
Merial points out that the extent of a herd’s gutworm exposure can be easily and simply assessed from a sample taken from the bulk milk tank – using the MOO Test. This test determines the amount of antibody to Osteragia ostertagi present in a sample, giving an assessment of the level of herd gutworm challenge.
The metabolic demands placed on cows during the post-calving period can lead to a negative energy balance, when energy gained from feed intake is less than that used for milk production. This natural ‘energy gap’ leads to weight loss; a parasite burden can make matters worse.
Sioned advises taking action to reduce the effect of this post-calving energy gap to maintain productivity levels. She said: “Management of cows in the weeks following calving should focus on maximising dry matter intake to correct the energy imbalance as quickly as possible. Studies have shown that cows treated for gutworm have improved appetites, and graze for up to an hour longer than untreated cows3. Grass is the cheapest form of nutrition so it makes sense to make the most of it.”
Merial also points towards studies which have shown that effective parasite control may have a beneficial effect4,5. Reduced body condition scores caused by the energy gap after calving may impact on reproductive parameters. In one study, cows treated for gutworm were back in calf 13 days sooner than untreated animals4.
Sioned said: "This has obvious implications for productivity. We need to look at employing a range of practical measures to ensure cows are as productive and efficient as possible, and this includes targeted worming where required.”
According to the company, effective parasite management of the replacement heifer during the rearing period is key to her future performance and productivity. Achieving breed-appropriate target weights throughout the rearing period is a crucial component of heifer rearing. The onset of puberty and the start of breeding are more closely linked to weight, body size and condition score than age. It is therefore critical to ensure that heifers reach approximately 60% of mature weight by 14 months of age in order to achieve a 24 month average age at calving.
Sioned said: “Losses in potential liveweight gain due to poor parasite control during a heifer’s first grazing season will not be recouped during the second year at grass6. She won’t catch up, and this will impact on her ability to meet important milestones.”
Getting heifers in-calf at the optimal time will help to reduce breeding costs and maximises the potential productive life of the animal. Heifers treated for gutworm have been shown to have a 20% higher conception rate at first service than untreated cattle2.
Merial says there is also evidence that parasite burdens exert physiological effects that directly impact on the parameters influencing performance and profitability of heifers, and increased mammary development and earlier onset of puberty have been observed in strategically wormed heifers in comparison to those left untreated7,8.
Sioned said: “Effective worming will mitigate the effect of parasites on fertility levels in growing cattle4, while still allowing them to build the necessary immunity required to prevent clinical disease in adulthood.”
Ceva Animal Health has announced two additional dates and locations for its ‘Building Success Around the Fertility Routine Visit’ CPD days for young vets.
Part of Ceva’s reprodAction programme, the courses are intended for recent graduates, or those new to dairy practice.
The two upcoming meetings, listed on VetSurgeon.org's new RSVP-enabled CPD & Events Diary, are to be held at The Best Western Dryfesdale Hotel in Lockerbie, Dumfries and Galloway on 22nd September and the West Lancashire Investment Centre in Skelmersdale, Lancashire on 23rd September.
The company says that the courses adopt a novel ‘physiology first’, practical approach to managing cattle reproduction, and have been set up to support vets in performing routine fertility visits. They cover various topics including: identifying clients’ goals, setting herd targets and increasing pregnancy rates.
Katherine Timms, Veterinary Advisor at Ceva, said: “We have had such positive feedback from the previous events, it has encouraged us to organise more, giving vets from other areas in the UK an opportunity to attend”.
“Routine fertility visits often intimidate recent graduates, as they are normally performed solo, with little or no support. This can make it hard for vets to build confidence, which this course addresses by not only providing knowledge but also by vets who are at the same stage in their careers to interact and share experiences.”
An attendee of the course held in April, Amy Cox from Nantwich Farm Vets, spoke about her highlights of the event, saying: “It really gave me the confidence in my own knowledge of cow reproduction and helped me build on what I’d already got.
“The lecturers were really engaging and the content was highly interactive which I feel helps you learn more. This is the second reprodAction CPD course that I’ve been on so I would recommend them”.
Paddy Gordon, Director of Shepton Veterinary Group, is one of the leaders of the event. He said: “Cattle reproduction CPD can be complex and is usually theory based; these events aim to cover the basics and most importantly, how to implement it all practically. This includes how to communicate concepts to farmers, through group discussion and role play and how to implement treatment protocols practically.”
Vets who are interested in attending either of the upcoming reprodAction Young Vet Initiative CPD courses can apply via Ceva Territory Managers, Bryan Hamilton on 07753 447226 or bryan.hamilton@ceva.com for the Lockerbie meeting and Kimberly Campbell on 07831 359128 or kimberly.campbell@ceva.com for the Skelmersdale meeting.
And if you're going, don't forget to use the RSVP facility on VetSurgeon.org to let other members know you'll be there.
Biogal has announced the launch of the PCRun Molecular Detection Kit, designed to give PCR results in clinic or in the lab within an hour.
The new kit doesn't require any other equipment, such as a thermocycler.
PCRun is a molecular assay based on the isothermal amplification of part of the HapI gene. The company says it is intended for the qualitative detection of pathogenic species of Leptospires only.
The PCRun has been tested at the OEI Leptospira Reference Laboratory in Ireland, on sample materials including urine and kidney biopsies collected from cows experimentally infected with L. hardjo as well as kidney cells.
According to the company, no false positive results were observed in all 63 samples tested and there was excellent correlation between Real Time PCR and PCRun reactions.
Results of the study and a list of serovars tested with PCRun are available from Biogal. See: http://www.biogal.co.il/products/pcrun
Merial Animal Health has revealed the latest MOO test figures which suggest that the productivity of four out of five UK dairy herds is compromised by high levels of gutworm.
The company says it has been helping dairy farmers to assess the level of gutworm challenge in their herds since 2009 by supporting and promoting MOO tests. The test measures the level of antibody to gutworm (Ostertagia ostertagii) that is present in a bulk milk sample and can determine if the herd has been exposed to low, medium or high challenge.
Data from five years of MOO tests shows that whilst there was a steady reduction in the number of herds with a high challenge between 2009 and 2013, the figure rose in 2014. In 2009, 93% of herds tested high and by 2013 this had fallen to 71% but this rose again to 88% last year.
Merial says that whilst these figures show an overall reduction in challenge since 2009, levels of gutworm across the UK dairy herd are still very high. Those animals affected will suffer from the negative impact of a parasite burden on productivity and fertility.
Between 2009 and 2014 nearly 900 dairy herds across the UK have been tested. During that time several counties had significant numbers of herds with high gutworm challenge results. This included Cheshire (85%), Cornwall (93%), Cumbria (91%), Dyfed (92%), Lancashire (90%), North Yorkshire (83%), Shropshire (86%), Somerset (86%), and Staffordshire (83%).
Sioned Timothy, veterinary adviser for Merial Animal Health, said: “Gutworm can significantly reduce the productivity of the herd. Although adult dairy cows develop immunity to gutworm that makes them resilient to outward clinical signs of infection, it does not prevent them from becoming infected with Ostertagia ostertagi. This parasite burden can reduce milk yield by as much as 2.6 litres per cow per day1”
She continued: “Gutworm may also have a negative impact on fertility. Removing damaging gutworms from dairy cows may improve their fertility and has been linked to reduced calving to conception intervals and improved conception rates2 to levels comparable with animals without a gutworm burden.
"Calving is another key period in the production cycle. Optimising cow and heifer management during this period is critical to the animal’s health and productivity throughout the subsequent lactation. Cows treated for gutworms around the time of calving have been shown to increase their grazing time by almost an hour compared to untreated cows3. Improved appetite and higher dry matter intake helps cows to bridge the energy gap; maximising their production, and reducing the time it takes to get them back into calf4.”
The MOO test figures show that the UK dairy herd continues to be affected by high levels of gutworm challenge. At a time when maximising productivity is vital to dairy business success, farmers should seriously consider testing their herd this autumn and develop a treatment plan with their vet or animal health adviser based on the result.”
MOO tests will be available in autumn 2015. The results of MOO tests are sent to both the farmer and their vet or animal health advisor, to enable them to determine the best course of action and treatment.References1 Reist et al, Effect of eprinomectin treatment on milk yield and quality in dairy cows in South Tyrol, Italy.

Merial is highlighting the results of an independent study published in July's Journal of Dairy Science which showed that treating acutely lame cows with the non-steroidal anti-inflammatory (NSAID) Ketofen (ketoprofen), alongside therapeutic trimming and the application of a block, resulted in a significantly better recovery rate compared to the other treatment protocols used.
In the study, Evaluation of treatments for claw horn lesions in dairy cows in a randomised controlled trial by Thomas et al1, 56% of the cows in the above treatment group were observed to be sound.
Sioned Timothy, Merial Technical Veterinary Manager (pictured right) said: "The lack of evidence to underpin a standardised approach to treating lameness in cattle has previously been highlighted2.
"This study demonstrates the value of using an NSAID as part of lameness treatment both for its welfare benefits, and also to reduce the impact of lameness on herd productivity through improved recovery rates. It also highlights the importance of implementing herd health protocols that focus on early intervention – identifying cows as soon as they become lame should be a priority for dairy farmers. With lameness cited as having a significant adverse effect on milk yield3 and cull rate in the herd, a proactive approach to lameness control is critical. Farmers should work with their vets and foot trimmers to ensure that when lame cows are identified they are treated in the most effective way.”
Sioned added: "The importance of routine mobility scoring cannot be underestimated. Clinical lameness has been shown to cause a decreased milk yield from up to four months before diagnosis 3, which can translate to a mean reduction of 357 litres per 305 day lactation. Furthermore, the impact on fertility and the long term impact on replacement is also acknowledged, with lame cows less likely to conceive and having an increased risk of conception failing."
Zoetis has announced the launch of Zulvac SBV, a new Schmallenberg vaccine licensed for use in cattle and sheep in two doses at a three week interval, the second at least two weeks before mating.
Zulvac SBV is licensed for use in cattle and sheep in two doses at a three week interval, the second at least two weeks before mating.
Duration of immunity is six months in cattle and seven in sheep. At the recommended vaccination timing, this covers the window of susceptibility during pregnancy; in sheep from day 28 to 56, and days 70 to 150 in cattle. Animals infected during these periods are at risk of malformed offspring and subsequent stillbirth.
The company says vaccination combined with insecticidal measures to control the midge vector remains the most effective way of protecting the population1 and ensuring a more unified level of immunity.
Zoetis vet Carolyn Hogan said: "Although SBV is now considered to be an enzootic pathogen in England and Wales, there is plenty of evidence that seroprevalence at farm level – particularly on sheep farms - varies. As immunity wanes, the proportion of herds and flocks naïve to SBV and at risk via introduction of naïve replacements increases. So the risk of reinfection in assumed enzootic areas is potentially underestimated2.
"Culicoides midges, the SBV vector, are widespread in Europe and move easily between farms and regions, allowing rapid spread of infection."
Carolyn says that whilst there have been no confirmed diagnoses of congenital abnormalities in calves or lambs from APHA in 2014 or 2015, unconfirmed anecdotal cases have been reported.
"We do not know whether our ruminant population is immune or susceptible and neither do we know if another SBV challenge will appear. Vaccination remains the most effective way of ensuring valuable livestock are protected."

Bayer Animal Health has announced changes to the product indications for Baytril 50mg/ml and 100mg/ml Solutions for Injection, which both contain enrofloxacin.
Baytril 50mg/ml and 100mg/ml Solutions for Injection, now have licensed indications for the treatment of sheep and goats.
Baytril 50mg/ml and 100mg/ml* Solutions for Injection are now licensed for the treatment of acute mycoplasma-associated arthritis due to enrofloxacin- susceptible strains of Mycoplasma bovis in cattle (*in cattle less than 2 years old.)
For the treatment of acute severe mastitis caused by enrofloxacin - susceptible strains ofEscherichia coli in cattle, the second injection of Baytril 100 mg/ml Solution for Injection may now be given subcutaneously, 24 hours after the first dose administered by intravenous injection. In this case, the withdrawal period following subcutaneous injection should be applied.
For more information, refer to the product data sheets at www.noahcompendium.co.uk and SPCs or speak to your local Bayer Animal Health representative.
Virbac has launched Neoprinil, an eprinomectin pour-on solution indicated for use against internal and external parasites in cattle, including gut and lungworms, mange mites, sucking and chewing lice, horn flies and warbles.
Neoprinil has a zero-day withdrawal period in milk and can be administered using the company's Farmpack and Flexibag.
The Farmpack is a backpack which holds a Flexibag of Neoprinil solution. The Flexibag is a bag designed to protect medication and preserve it once it has been opened. The two together were awarded the 2014 PharmaPack Award for Innovative Packaging.
Neoprinil offers a one year stability period once it has first been opened and requires no special conditions for storage. It is presented in 2.5L, 4.5l and 8l pack sizes.
Product Manager for Large Animals Brigitte Goasduf MRCVS said: "A high worm burden can have adverse effects on the herd's productivity and performance and so it is advisable to ensure infected animals are treated as part of a Herd Health Plan. Eprinomectin is a tried and trusted parasiticide and studies confirm that it can have a positive impact on both milk production and on weight gain. Its zero day withdrawal period is a major benefit for dairy farmers.
"With the launch first of Deltanil and, now, Neoprinil, we are reinforcing our commitment to work with veterinary surgeons and farmers to understand the everyday challenges they face and to provide practical, effective solutions. We offer a comprehensive parasiticide range with a dispensing system that sets a new standard for convenience and ease of use."
Bayer Animal Health has announced the launch of, Dinalgen (ketoprofen), an NSAID injection approved for use in cattle, pigs and horses.
Dinalgen is available as a 150mg/ml Solution for Injection, and Bayer says the more concentrated format allows the product to provide the smallest dose, fast relief NSAID currently available for cattle in the UK.
In cattle, Dinalgen is licensed for the reduction of inflammation and pain associated with lameness, post-partum, and musculoskeletal disorders; the reduction of fever associated with bovine respiratory disease; and the reduction of inflammation, fever and pain in acute clinical mastitis in combination with antimicrobial therapy where appropriate. The withdrawal period for milk is zero hours and for meat two days.
In pigs, Dinalgen is licensed for the reduction of pyrexia in cases of respiratory disease and postpartum dysgalactia syndrome in sows, in combination with antimicrobial therapy.
In horses, Dinalgen is licensed for the reduction of inflammation and pain associated with osteoarticular and musculoskeletal disorders, including lameness, laminitis, osteoarthritis, synovitis, and tendinitis. It also aids the reduction of visceral pain associated with colic.
Sharon Cooksey, MRCVS, FAP group product manager at Bayer, said: “We are excited to have this new addition to our portfolio. It is a good fit with our existing products.
"A recent field study*, carried out by Nottingham university, has shown that NSAID (ketoprofen) treatment maximises the chance of recovery from lameness in dairy cattle. Lameness remains one of the “big three” issues in dairy practice so maybe it is time we moved on from hoof blocks and/ or trimming in isolation and onto a more multi-layer approach. We have some great support tools in the pipeline to help both vets and farmers recognise and manage animals at risk for lameness.”
