Life Technologies has announced the launch of a new ELISA test for bluetongue virus (BTV) antibodies.
According to the company, studies have confirmed that the LSI VET Ruminant Bluetongue II-serum ELISA can detect antibodies to BTV in experimentally infected sheep after 6 days, and in cattle after 7-8 days - several days sooner than some other commercially available test kits, including the company's previous ELISA test which the new product has replaced.
Life Technologies asked the UK's Pirbright Institute, the European Union Reference Laboratory for BTV, to conduct a preliminary assessment of the new test. The new test was able to detect antibodies in all 24 BTV reference sera and BTV 26 held by Pirbright, and showed high sensitivity in a longitudinal study of experimentally infected animals.
The Pirbright study also demonstrated that the LSI VET Ruminant Bluetongue II-serum ELISA could detect BTV antibodies in cattle and sheep that had been vaccinated with an inactivated Bluetongue vaccine.
The new test was developed by Life Technologies Animal Health in its research laboratory near Lyon in France and will be available in EU countries via Life Technologies Animal Health distributors according to local regulatory requirements (see www.lifetechnologies.com/lsi-animal-health) for details.
Pneumonia-induced lung damage could be costing some cattle almost 74kg a year in lost lifetime growth potential with even moderate damage resulting in animals losing 39kg over an 18 month beef finishing system. These are the figures from a major collaborative study between Schering-Plough and Blade Farming, announced yesterday. They suggest that some producers may not be treating cattle pneumonia as effectively as they could. The project also highlights how better abattoir feedback can be used to improve cattle pneumonia management regimes on farm. In the study, 645 commercial beef animals from 15 units were examined at slaughter for evidence of lung damage. Data on carcase weight, age and grade were also collected to allow estimated daily live weight gains (EDLWG) to be recorded. According to project co-ordinator Paul Williams MRCVS from Schering-Plough, the research team recorded a significant level of pneumonia-induced lung damage in the slaughtered cattle. “Nearly half the cattle (48%) examined on the slaughter line had some level of lung damage. But there was also huge variation between units, with all the cattle from one particular farm having damaged lungs,” he said. The researchers also established that the extent of lung damage was strongly associated with reduced EDLWG. “The more lung lobes that are affected, the greater the potential daily liveweight gain loss and those cattle that had the most lung damage experienced a significant reduction in EDLWG of 202g per day throughout their entire lifetime. “For the animals with any degree of lung damage (310 cattle), the average reduction in weight gain over 14 months was 15kg – equivalent to a financial loss of £16.90 per animal based on a live weight price of £1.10 per kg. So the overall loss for this group of animals was potentially £5,239 – money the industry simply cannot afford to lose,” Paul Williams stressed. “In addition, those carcases with lung damage were significantly more likely to have a lower conformation grade and so receive an even lower price,” he explained. Blade Farming managing director Richard Phelps pointed out that the study had convinced him that paying closer attention to minimising pneumonia-induced lung damage could easily make some beef producers an extra £40-£50 an animal. “All the cattle we take look healthy, but I’ve been surprised at the level of undetected lung damage once the animals have been slaughtered. This lung scoring trial work in the abattoir is now helping us assess just how much lung damage diseases like pneumonia can cause. The feedback will be able to help producers reassess early stage rearing issues and be more vigilant. It’s not just grading issues that we are concerned about. Blade Farming consultant veterinary surgeon Rob Drysdale from the Westpoint Veterinary Group stressed that whilst pneumonia prevention should be the number one objective for all cattle producers, having an effective disease treatment protocol in place is increasingly vital – and particularly one that prevents permanent lung damage from occurring. He said: "Pneumonia infections can quickly damage lungs and once this happens the animal will not be able to express its full genetic potential. This means that even if the affected animal survives it is likely to have damaged lungs for the rest of its life, and this will reduce productivity and growth." T
FMDMost of you will be aware that IP8 was declared yesterday. This is a farm in the POZ that was slaughtered on suspicion after detection during surveillance visits. This has lead to further slight changes in the boundaries of the PZ and SZ. These were early lesions and initial laboratory results confirm this.
The epidemiology of the spread of FMD in the area north of Egham suggests that cattle on 4 premises in the vicinity of IP8 have been exposed to infection either via possible aerosol or fomite spread and are likely to develop disease. These premises will be culled as dangerous contacts.
BLUETONGUEThe various zones for controlling Bluetongue have now been defined. These are difficult to describe because they use roads etc. as boundaries but detailed maps and description of the boundaries are available at:
http://www.defra.gov.uk/animalh/diseases/notifiable/bluetongue/pdf/declaration-bt-pzcz290907.pdf
When farms straddle a road that is a boundary the whole of the farm is classed as being in the zone. It may be possible to put parts of a holding that is outside the zone as a separate unit with consultation with local Animal Health office.
The movement restrictions between the various FMD and BT zones are available at
http://www.defra.gov.uk/animalh/diseases/notifiable/bluetongue/movements/index.htm
Defra are worried that farmers are not reporting cases of BT because they feel there is nothing that can be done so why bother. It is still a notifiable disease and there is a need to monitor spread for various trade implications. There are, of course, likely to be welfare considerations with clinically affected cases. These will need to be addressed with veterinary consultation and may involve symptomatic treatment or euthanasia.
The prevalence of the disease in infected herds/flocks is still low with 1:53 and 1:190 being affected on surveillance.
BCF has launched the Easi-Scan remote display, designed for on-farm use.
The company says the Easi-Scan offers unprecedented display performance, is very portable (weighing less than 2Kg) and very rugged. According to the company, Its 8.4" transflective LCD screen provides excellent quality images for fertility and pregnancy scanning meaning it can be used as the sole display for BCF's Easi-Scan and Duo-Scan ultrasound scanners. And with a dedicated channel button, you can switch between all available ultrasound channels, allowing you to view a number of examinations at once.
The Easi-Scan is also available with a Gorilla pod allowing it to be attached to railings and a carry strap.
Gavin Mitchell from BCF said: "At BCF innovation is key; we have invested a lot of time developing a remote display monitor that is well suited to the needs of the market. Through listening to our customers, we feel we have successfully achieved this. It is ideal for training purposes and viewing multiple exams. It is also the only wireless and splashproof remote ultrasound display on the market."

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.
London's Savile Row was turned into a sheep field today, to highlight The Campaign For Wool; a coalition of industry groups convened by HRH The Prince of Wales to educate consumers about the benefits of wool.
As the sheep grazed, the Row's famous tailoring houses held events where the public could find out more about the natural, sustainable qualities of wool.
Douglas Cordeaux, Managing Director of West Country woollen mill Fox Brothers, one of the organisations behind the promotion said: "We have a collective responsibility to champion this versatile, sustainable and natural fibre, the production of which involves far lower carbon emissions than man‐made alternatives. We need to support farmers who are the custodians of our rural landscape and truly value the qualities of this wonderful resource, which is used to weave the finest luxury cloth you can buy."
John Thorley of the Campaign for Wool said: 'I'd like to see wool re-established as a fibre of consequence where workers get paid properly and people recognise that this animal is useful to the farming sector in a multitude of ways.'

The British Occupational Hygiene Society (BOHS) has announced the publication of a book on controlling skin exposure and wet work. The book aims to fill a knowledge gap about dermal exposure risk management in workplaces which are particularly affected, such as veterinary practices.
The consequences of a failure to adequately control dermal exposure to hazardous agents do not always become apparent until years after exposure, and because of this, many employers are either ignorant of the consequences or ignore the potential for ill-health until it is too late. In Great Britain, over 29,000 people are suffering from work-related skin disease and every year over 3,500 new cases are reported. Alongside this, many workers are unaware of the ways in which skin comes into contact with chemicals, or how dermal exposure can contribute to inadvertent inhalation and ingestion exposure.
Healthcare workers are susceptible. Vets and nurses are, for example, at risk from disinfectants, detergents, wet-work, latex gloves, anaesthetics, antibiotics and antiseptics, phenothiazines, formaldehyde, glutaraldehyde and liquid chloroxylenol.
The book provides an introduction to the structure and functions of the skin, information about the diseases caused by dermal exposure and the occupations and chemicals involved, regulatory requirements related to dermal exposure at work, exposure and risk assessment, and risk management strategies. It is both comprehensive and accessible, and clearly illustrated with photographs, figures and tables throughout, ensuring that it will be of practical use. As a result, BOHS believes that it will make an important contribution to increasing knowledge about control of dermal exposure, and encourage more effective control measures to be introduced in workplaces.
‘Controlling Skin Exposure to Chemicals and Wet-Work' is available for £19.99 and can be purchased on-line via RMS Publishing, www.rmspublishing.co.uk/BOHS.html and Amazon, or by posting/faxing the order form which can be downloaded from the Publications section of the BOHS website.
Bimeda UK has announced that Endofluke 100mg Oral Suspension has been approved for use in dairy cows, with a milk withdrawal period of 45 days + 48 hours.
Endofluke is licensed for use in cattle and sheep and its active ingredient, triclabendazole (100mg/ml) kills all three stages of liver fluke.
Bimeda UK Sales Manager, Andrew Lane said: "This is great news for the UK's dairy farmers. Endofluke has long been favoured by British & Northern Irish farmers as a liver fluke treatment, due to its ability to offer complete chronic and acute fluke control in both sheep and cattle. It is proven to be highly effective against early-immature, immature and adult liver fluke, and to now be able to extend these benefits to dairy cows, is fantastic news for the UK's dairy farmers."
Endofluke is a POM-VPS product.

322 farmers took part in the survey, 83% of which had a flock of over 100 ewes.
Three quarters of them had experienced abortions in their ewes during both the 2018/2019 and 2019/2020 lambing seasons. Of those that experienced abortions during the 2019/2020 lambing season, a quarter reported that the problem occurred in more than 2% of their flock and 44% of them did not ask their vet to investigate.
Katherine Timms, Ceva Animal Health’s ruminant veterinary advisor said: “Farmers who decide not to investigate why their ewes are aborting may well experience an abortion storm during the following year’s lambing season as Chlamydophila abortus, the bacteria that causes EAE, has the ability to lay latent in ewes until the next pregnancy.
“This means that one infected sheep shedding at lambing has the potential to infect multiple ewes that will almost certainly abort at their next lambing. The consequences can be financially and reproductively devastating for farmers and it’s advisable that vets raise awareness of EAE testing with their clients to help prevent this from happening. Ceva’s Assure Ewe programme offers farmers subsidised farm serology testing for Chlamydia abortus. Aborted ewes can be tested for Chlamydia abortus, ideally from three weeks to three months after lambing.”
Of the 47% of farmers that are not vaccinating against EAE, 57% said they would consider it. Reasons not to vaccinate included farmers believing that they had closed flocks (59%) and EAE not having been diagnosed (57%). Only 20% decided not to vaccinate because of cost and 25% because they did not feel it was worthwhile.
Ceva is continuing its ‘For Flock’s Sake – Vaccinate!’ initiative during 2021 to help raise awareness of EAE and highlight the importance of vaccination. This year, Ceva is also highlighting the importance of testing aborted ewes through its ‘For Flock’s Sake Get Tested’ campaign which encourages the submission of samples to a diagnostic laboratory or blood sampling after lambing has finished.

The University of Bristol's School of Veterinary Sciences at Langford has opened a £2 million state-of-the-art dairy farm.
Wyndhurst Farm's dairy unit has undergone a major rebuild in order to provide a world-class practical teaching environment for around 600 veterinary students, as well as a facility that can be used to support research and the continual professional development of veterinary surgeons, farmers and others involved in the dairy industry locally, nationally and internationally. Professor Jo Price, Head of the School of Veterinary Sciences, said: "This is an exciting time for the Vet School. The new dairy unit will enable our undergraduate and postgraduate students to be taught in a world-class facility. It will provide the best standards of animal welfare for our dairy herd and will support our research on the prevention and treatment of diseases of farm animals."The farm, which is approximately 250 acres, includes numerous features to ensure high welfare standards. The dairy herd will be housed in deep sand bedded cubicles, with parts of the floors covered in soft rubber to protect the cows' feet and when housed cows will be fed a total mixed ration using grass, maize and whole crop wheat silages grown on the farm.Since the new facility has been built the farm's herd of Pedigree Holstein cows have increased in number from 110 to 180 cows and will soon reach 200, with each cow giving over 9,000 litres of milk per year. The farm also has a newly established breeding flock of 100 New Zealand Romney ewes. Since 2010 it has been managed by Velcourt Farm Management.
The new facilities use teaching aids and models to allow students to refine their practical skills and build confidence before being let loose on real patients.
As part of the official opening, Princess Anne toured the School of Veterinary Medicine, where she met with staff and students and saw a demonstration of a new equine gut model that offers an alternative to using live animals for research into the gut microbiota of horses and how they are affected by diet, disease and medication.
Professor Chris Proudman, Head of the School of Veterinary Medicine, said: "We are honoured to welcome The Princess Royal to the Vet School today, and very grateful that Her Royal Highness has officially opened the Large Animal Clinical Skills Facilities. Preparing students for life as a vet is our number one priority; the hands-on experience they will get through the use of this facility is invaluable and enables them to give the best possible care to all animals.
"We are also very grateful to the Longhurst family, without whom these teaching resources would not have been possible – their generosity is helping us to teach the vets of the future."
According to the RCVS, 86% of veterinary surgeons, and 92% of veterinary nurses have so far failed to vote in this year's council elections.
There's still time: voting for the RCVS Council and VN Council doesn't close till 2nd May and 28th April respectively.
Voting can be done online: http://www.rcvs.org.uk/Templates/Internal.asp?NodeID=205006, where you can also read each candidate's manifesto.
The BVA Animal Welfare Foundation has announced the availability of an updated version of its A3 poultry poster designed to assist veterinary surgeons identify diseases in free-range birds.
Based on information compiled by Victoria Roberts, Honorary Veterinary Surgeon to The Poultry Club, the BVA says the poster provides an invaluable source of information on diseases affecting exhibition chickens, hens, ducks, geese, turkeys, ornamental waterfowl, quail, ornamental pheasants, guinea fowl and peacocks.
The poster details the symptoms of different diseases, the cause, treatment and species affected as well as sections covering common problems and some causes, common diseases by age and life expectancy for the various bird species. A separate highlighted box contains useful tips for veterinary surgeons to pass on to their clients.
Copies of the poster have been circulated to BVA members as an insert in this week’s Veterinary Record. For further copies (free of charge) please ring 020 7636 6541 and ask for the BVA AWF or email bva-awf@bva.co.uk stating your name and postal address, and quoting AWF Poultry Poster.
MSD Animal Health has launched Expertis Udder Health, a farm management tool for veterinary surgeons to better enable them to monitor and improve udder health in dairy cattle.
Expertis was presented to vets at the International Conference on Udder Health and Communication which took place in Utrecht this week.
Expertis Udder Health consists of a software programme together with educational and communication tools to help veterinary surgeons and farmers find the causes of mastitis more easily.
The Expertis Udder Health program consists of four steps: 1. A farm intake questionnaire about setting goals puts the farmer in a central position, and allows for careful listening in order to align with his/her objectives. 2. The data is analyzed, leading to the identification of the right focus points that are needed to identify areas for improvement. 3. These focus points are presented as fact sheets, i.e. a check list of risk factors for mastitis within the focus point. 4. The information is synthesized into an automatic summary of the actual situation, the udder health objectives and an open space to fill in the tailor-made advice to the farmer for improvement of the udder health status on his farm.
Jantijn Swinkels, DVM, Global Technical Director Pharmaceuticals within the Ruminants Business Unit at Merck Animal Health said: "The structured approach offered by Expertis Udder Health takes into account that mastitis is a multifactorial disease and covers all aspects that influence udder health. To save time, the analysis ensures that the focus is on the most important issues, which can differ greatly from farm to farm. The existing services provided within this tool can be used to optimize udder health on the farm".
Rinse Jan Boersma, MSc, Global Director Dairy Cattle at Merck Animal Health added: "We have developed Expertis to support veterinarians and farmers by improving our service level as well as to contribute to good veterinary practices by implementing preventive measures and prudent use of antibiotics."
MSD says that as a consequence of the reduced milk production, discarded milk, veterinary and treatment costs and extra labor costs, mastitis is considered the most important cause of economic loss for dairy operations. Recent data from Sweden indicates an average economic loss of €278 per case of clinical mastitis and of €60 per case of sub-clinical mastitis.*
The Expertis Udder Health program is being rolled out country to country, and will be distributed to veterinary surgeons via local MSD Animal Health representatives.

Intervet/Schering-Plough Animal Health has launched its complimentary blood testing service that allows practitioners to investigate one of the main infectious causes of early embryo loss in sheep flocks.
The annual subsidised Barren EweCheck diagnostic scheme is available from 1st December 2009 until 31st March 2010 for breeding ewe flocks. The service establishes whether Toxoplasma gondii is potentially implicated in any empty or aborting ewes.
ISPAH says that data from the 2009 scheme showed that 69% of flocks had been exposed to the toxoplasma parasite at some point before blood sampling. As a result, practitioners were able to give clients receiving a positive diagnosis timely advice on disease control and the benefits of a Toxovax vaccination regime.
Further information and the 2010 Barren EweCheck pads are available directly from the company's Veterinary Support Group by calling 01908 685685.
Dairy vets will soon be receiving a DVD highlighting the economic losses due to coccidiosis in cattle, from Janssen Animal Health.
According to the company, coccidiosis is a major cause of scouring and poor growth rates in calves yet recent findings have demonstrated that a massive 61 per cent of the economic loss occurs in sub-clinically infected calves that are not showing any obvious clinical signs. Treated calves have been shown to put on 20 per cent more weight than untreated calves1. Coccidiosis infects between 16 and 27 per cent of adult cattle who act as reservoirs of the disease2,3,4,5. This means that most calves are likely to become exposed to the infectious form of the parasite. After the age of 6 months the majority of calves acquire immunity but if they are exposed to a massive challenge before that time due to large numbers of the coccidial oocysts or due to a stress factor, sub-clinical or clinical disease occurs.
The DVD describes the challenges involved in diagnosing coccidiosis and how to interpret faecal oocyst counts, as well as some of the characteristics of sub-clinical infection in calves. The benefits of metaphylactic and preventative approaches to treatment with Vecoxan®, the only anticoccidial drench licensed for beef and dairy cattle at any age, indoors and out, are discussed.
Nigel Underwood from Janssen Animal Health said: "The diagnosis of non-specific scour is problematic at best but it is important that vets have coccidiosis at front of mind when considering the differential diagnosis. Prompt treatment of the whole batch of calves can stop the disease in its tracks and does not interfere with the development of future immunity. We hope this DVD will provide an update on the latest thinking and help increase recognition of this disease."
The DVD will be sent out in February and any vet with an interest in the disease who does not received one before the end of the month should call Janssen on 01494 567555 to request a copy.

Novartis Animal Health has launched 'The Wormer Decision Tree', an online tool to help veterinary surgeons in giving sheep farmers the most up-to-date advice about worming.
Lesley Stubbings, SCOPS representative and Independent Sheep Consultant said: “Choosing the right wormer group is hugely important and there remains much confusion especially when it comes to anthelmintic resistance.
“Worms, including resistant and multi-resistant species, are threatening the productivity of sheep farms. However with a well-thought-out worming strategy that uses both the new wormer groups, in association with existing wormers, it is possible to slow resistance.”
Results of the Farming Against Wormer Resistance (FAWR) campaign survey, conducted in 2013, revealed growing concern about wormer resistance among farmers - but confusion about the best course of action to take.
Fiona Anderson, Novartis Animal Health Veterinary Manager said: "This tool has been developed adhering to SCOPS principles and is designed to ensure a consistent responsible approach is used when prescribing anthelmintics.
"Available only to SQPs and vets, it will be a valuable tool to train new staff and use with farmers, to explain which of the five drench classes are appropriate for particular sheep groups at specific times of year."
The Novartis Wormer Decision Tree asks three key questions: the type of sheep being dosed, the purpose of the dose, and the farm's resistance status. It then produces a recommendation of the required active ingredient, along with more detailed information to support the recommendation. There is also a calculator which provides a dose rate and cost per dose based upon the recommendation.
To use the decision tree, you must first register on the Novartis Farm Animal Health website: www.farmanimalhealth.co.uk. Then head here: www.farmanimalhealth.co.uk/wormerdecisiontree
CEVA Animal Health is supplying a free, multi-dose injector gun with a self-sterilising needle system, with the purchase of bulk quantities of its luteolytic and uterotonic prostaglandin Enzaprost, while stocks last.
According to the company, the use of naturally occurring prostaglandins such as Enzaprost play an important role in any fertility management programme, working by causing lysis of the corpus luteum. Enzaprost can be used to control the timing of oestrus and synchronisation for AI; for the treatment of sub-oestrus or silent heat; for the induction of abortion up to day 120; for the induction of parturition and as an aid in the treatment of chronic metritis or pyometra where there is a functional or persistent corpus luteum. Natural prostaglandins also have a uterotonic effect which may be useful in the treatment of 'dirty' cows.
CEVA says any multi-cow injection programme has its risks, and that experience has shown that one in 250,000 injections can result in clostridial infection. Invariably this occurs in sequential animals, with the causal agent found in the bottle as a result of inadvertent needle contamination. Multi-dose syringes reduce the number of needle punctures into a bottle and the Sterimatic caps clean the needle before and after each injection helping to minimise the risk of infection. One Sterimatic cap can be used for 72 hours or up to 100 injections. The covered needle also provides increased safety for the operator, resulting in fewer needle stick and scratch injuries.
To find out how you can receive a free multi-dose injector with the Sterimatic needle protector system, which includes five caps and one needle protector, please contact your local CEVA territory manager

Defra has today published reports from the Health and SafetyExecutive and Professor Brian Spratt, of Imperial College London,into the recent outbreak of Foot and Mouth Disease in Surrey. The report is available here.
Intervet/Schering-Plough Animal Health has announced that it has received marketing authorization from the European Commission for a single-shot vaccination schedule of its Porcilis PCV vaccine against porcine circovirus type 2 (PCV2) infections.
The new approval allows vaccination with 1 dose of 2 ml in pigs from an age of 3 weeks onwards (known as the 1 - 2 - 3 approach) in the case of low to medium levels of maternal antibodies against PCV2, and also to include reduction of mortality as an additional indication. This new single-shot application for Porcilis PCV offers additional flexibility over the currently available dosage scheme of this vaccine, which has been available in Europe since April 2009.
Intervet/Schering Plough says the major characteristics of Porcilis PCV are that: (1) it contains the Cap-2 subunit antigen coded by ORF2 and therefore induces strong immunity against PCV2 infection; (2) it is combined with XSolve, an adjuvant offering immunity until the end of the finishing period; and (3) is able to break through of all levels of maternally-derived antibodies in piglets depending on the vaccination schedule used.
The company adds that one single dose of Porcilis PCV has been demonstrated to induce both humoral and cell-mediated responses against PCV2, despite the presence of low to medium levels of maternal antibodies. According to a recent study published in Vaccine, the immunity induced by a single dose of the vaccine resulted in reductions of viremia, viral shedding and viral load in tissues in vaccinated pigs as compared to controls. Field trials have also demonstrated that vaccination of pigs at 3 weeks of age or older reduces the presence of virus load in the blood and reduces weight loss associated with PCV2 infection during the fattening period.
Infection with PCV2 is known to cause a variety of syndromes in pigs, together known as Porcine Circo Virus Disease (PCVD). Symptoms may include clinical signs such as weight loss or failure to grow, enlarged lymph nodes, difficulty in breathing, pale skin and jaundice.
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
Vets, consultants and other advisors should encourage dairy farmers to make use of available information to help improve their herd's performance and profitability through breeding. This is the message from DairyCo breeding+ director, Marco Winters, who says farmers should use genetics to improve not only milk production, but also health, welfare, management and type traits.
Breeding briefs, a new booklet from DairyCo, identifies some genetic improvement tools that allow farmers to make better breeding decisions and concentrates on how to use them in practice. And for those who feel confronted by an overload of information, the booklet helps identify the figures to seek out and prioritise.
Breeding decisions are cumulative: their effects build up over the generations so a problem can be introduced or cured over just a few years. A series of poor breeding decisions can mean the difference between profit and loss; even between a business's survival and failure. Yet the time, cost and effort needed for a good breeding decision to be made is much the same as those needed for a bad one.
Mr Winters says: "High quality cattle are at the heart of profitable dairy farming and this requires good quality genetics. Without these, however good farmers' management, there is a ceiling to their herd's performance and profitability. Vets, consultants and other dairy advisers have an important role to play in helping farmers access the information they need to make informed decisions."
