Janssen Animal Health is advising vets to be on the look out for coccidiosis as the spring lambing season approaches: cases usually rise in March and peak in April and May.
According to the company, some reports also suggest that the incidence of coccidiosis in calves may apparently increase during the grazing months. However, vets are reporting that interpretation of laboratory tests used to confirm diagnosis, such as oocyst count, can be problematic due to the ubiquitous nature of the Eimeria parasite in the UK.
Young animals may be infected by oocysts shed by asymptomatic carriers or infected older cohort animals. Low levels of challenge can help young animals develop immunity but exposure to high oocyst numbers, particularly in combination with stress can lead to clinical and subclinical forms of the disease. Diagnosis can be problematic, particularly in subclinical cases of disease where failure to gain weight is the main presenting sign and in clinical cases the differential diagnoses include all causes of scour in young animals.
Janssen Animal Health has suggested a few indicators that may be useful in identifying cases of coccidiosis. The Vecoxan Coccidiosis Survey in 2008 and 2009 asked farmers about their experiences of coccidiosis and identified that bad weather was a major trigger particularly in lambs; while castration and weaning were also factors in calves. As the parasite life cycle is 21 days, vets should be alert to disease 2-3 weeks after a stressor event.
The company has also suggested a few guidelines to aid interpretation of laboratory results:
Janssen says Vecoxan (diclazuril) does not interfere with the development of immunity and kills all stages of the parasite in the host.
Intervet has announced that its bluetongue vaccine, Bovilis® BTV8 has been granted a licence by the Veterinary Medicines Directorate (VMD). The licence, which is the first for a bluetongue vaccine in the UK, sets out dose rates and treatment regimes for the product use.
The recommended dose rates for animal over one month of age are as follows:
Sheep – 1 x 1ml, injected subcutaneously.
Cattle - 2 x 1ml, approximately three weeks apart, injected subcutaneously.
In successive years, re-vaccination should be given two weeks prior to the risk period.
Treated animals should have protective immunity three weeks after the initial course. Bovilis BTV8 should only be administered to healthy animals. Treated stock may have a slight swelling at the site of injection.
The vaccine must be stored at between 2ºC – 8ºC and, once opened, should be used within eight hours. The vaccine is available in 20ml and 50ml bottles. The licence recommends the use of multi injection vaccination systems.
Intervet will be supplying a discounted 1ml vaccination gun into the market.
Defra has published an epidemiology report into the Avian Influenza outbreak confirmed in Oxfordshire on 4 June. The report concludes that, at as of 11th June, the outbreak was confined to a single premises, and there is no evidence of infection in the Protection Zone or of spread to any other premises. However, investigations continue. The report suggests that it is possible that the Highly Pathogenic H7N7 Avian influenza derived from a Low Pathogenic strain already present on the farm. Analysis and investigations are ongoing, and a number of source hypotheses are being considered. Chief Veterinary Officer, Nigel Gibbens, said: "The UK is at a constant but low level of risk of the introduction of Avian Influenza, and the report highlights the need for flock owners and poultry vets to remain vigilant for signs of disease, including the possibility of low pathogenic Avian Influenza. I would encourage all keepers to maintain good quality records and practise high standards of biosecurity." The Protection and Surveillance Zones remain in place. Further surveillance, testing and epidemiological work on this outbreak are ongoing.

Defra has announced that the Bluetongue Protection Zone will be extended again on Monday 21 July, following the delivery by Intervet of almost 2 million additional doses of Bluetongue serotype 8 (BTV-8) vaccine. Vaccination is only permitted within the Protection Zone. In accordance with the Bluetongue vaccination plan, the Protection Zone will be extended to cover Worcestershire and the districts in North Yorkshire (Scarborough, Ryedale, Hambleton & Harrogate), Cheshire (Macclesfield, Congleton & Crewe and Nantwich) and Greater Manchester (Rochdale, Oldham, Tameside and Stockport) previously in the Surveillance Zone. Defra will continue to roll out vaccination as vaccine is delivered, in line with the vaccination roll-out plan. The additional vaccine is available for use in the existing Protection Zone from today. Livestock keepers in the areas coming into the Protection Zone will be able to obtain the vaccine from Monday. However, they are encouraged to order vaccine so that they can protect their livestock at the earliest opportunity. Protection Zone restrictions will apply to those keepers coming into the extended zone. Animals can only be moved out of the Protection Zone if they are vaccinated, naturally immune or moving for slaughter, subject to meeting certain conditions. Please refer to the Defra website for further guidance. Defra also confirmed that the Merial BTV-8 vaccine has been awarded a provisional marketing authorisation from the Veterinary Medicines Directorate. The granting of a provisional marketing authorisation is an important step in confirming that the vaccine will be safe and effective. On 11 June, Defra placed an order with Merial to deliver 13 million doses of BTV-8 vaccine, eight million for use in England and five million for use in Wales.
A recent UK Mastitis Panel meeting, sponsored by MSD Animal Health, has concluded that a lack of expertise in drying off and teat sealant administration is the limiting factor preventing more widespread adoption of selective dry cow therapy protocols in UK dairy farms
The panel representing practising dairy vets, research and Government agreed that whilst the use of selective dry cow therapy was at a relatively low level in UK dairy herds at the moment, a momentum was building that could see as many as half the nation’s herds adopting the practice within a few years.
Dr Martin Behr, technical manager at MSD Animal Health and chair of the UK Mastitis Panel meeting, said: "There is growing pressure from the milk processors and some supermarkets to see a reduction in antibiotic use on dairy farms, and dry cow therapy is one area under the spotlight.
"We know from our own training workshops with vets and farmers that the level of expertise in administering teat sealants, for example, is relatively low. Only about 30 percent of vets attending these workshops had any experience at all in administering a teat sealant."
The view from many on the mastitis panel was that there was a knowledge gap on farms when it comes to dry cow therapy protocols and that this presented a significant opportunity for vet practices.
Dr Behr added: "Mastitis control in general offers vets an opportunity for proactive engagement with farmers, but it is a notoriously difficult area to establish routine work. With the pressure on farms to adopt selective dry cow therapy and the need for training, there is perhaps a new opportunity for practices with a real interest in mastitis control to build stronger and more preventative strategies with dairy farmers."
Veterinary practices with an interest in training on dry cow therapy and teat sealant use are advised to contact their MSD Animal Health account manager for details of future workshops.

BCF Technology has published a new clinical guide to the non-reproductive applications of ultrasound in farm animals.
Kimberly Palgrave BS BVM&S, created the booklet with the aim of helping veterinary surgeons understand the value in using ultrasound for more than reproduction purposes.
BCF says On farm ultrasound uses: Beyond pregnancy diagnosis provides key clinical descriptions and tips, along with normal and abnormal ultrasound images to show how ultrasound can aid in diagnosing various on-farm conditions you may be presented with, such as scanning the teat to detect stenosis, the umbilical area for an abscess, and even the thorax for help to diagnose BRD.
Kimberly said: "This clinical guide was created to help vets get more out of on farm ultrasound than just pregnancy diagnosis. There are a range of other uses for ultrasound on farm and this guide explains how to use your equipment for these applications. As always we are happy to receive feedback on any of our clinical materials."

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
Improve International has announced that it is to hold the first conference aimed specifically at Official Veterinarians.
Taking place from 22-23 October 2015, Improve says the conference aims to provide a forum to update OVs on the latest developments and thinking on all aspects of OV work and to provide an opportunity to network and share experiences and ideas.
Organised in association with the Animal & Plant Health Agency (APHA), the Official Veterinarian Conference programme includes a two-day stream of large animal lectures and round-table discussions on topics including Bovine TB, Brucellosis, Anthrax, Sheep Scab and other important diseases.
A lecture stream for small animal practitioners will provide updates on export regulations and small animal exotic diseases, with dedicated lectures for equine practitioners also running on Friday 23 October.
Speakers at the event include Peter Jinman, Chair of the RCVS Certification Sub-Committee (pictured right); Dr Tim Brazil, Directorate of Equine Medicine on the Move and Andy Paterson, Veterinary Head of Intervention Epidemiology. An exhibition of the latest products and services for OVs will run alongside the conference which takes place at the Alexandra House Hotel and Conference Centre, near Swindon, where Improve International is based.

Research on ovine parasite Toxoplasma gondii, carried out at the University of Salford, could have a significant economic impact on the sheep farming industry - potentially saving the lives of 5% of the UK lamb population.
Postgraduate student Emma Morley has been working as part of a large research team, looking at the importance of transmission routes of T. gondii (the cause of the disease toxoplasmosis) within different mammalian groups.
A scholarship from the Perry Foundation, which funds research benefiting the farming industry, allowed Emma to launch her own study at the School of Environment & Life Sciences.
Salford parasitologist Professor Geoff Hide said: "Emma's research may have some significant impacts on sheep farming. Nearly 5% of lambs are lost to Toxoplasma in the UK so it's of major economic importance as well as an important animal welfare issue."
He said that one of the key things Emma's research has shown is that the advice currently given to farmers may be causing an increase in the level of the disease rather than controlling it. "Farmers are advised to breed from ewes that have lost lambs to Toxoplasma but Emma's results show that what farmers should be doing is breeding from ewes that do not have the parasite," he said.
This is the call to Government from an industry-wide stakeholder group that has joined forces and vowed to do everything in its power to stamp out the disease which is seeing upwards of 28,000 cattle a year culled.
The industry stakeholder group has put its name to an eight-point statement of agreement following the non-decision announced by the Secretary of State, Hilary Benn, on dealing with bTB.
Included in the eight points is a call for an independent body to take on the future decision making for animal health; a commitment of non-participation in the TB Partnership Group as announced by the Secretary of State; and an industry policy of non-participation in discussions on cost sharing and responsibility on animal health and welfare issues.
The NFU, which hosted the stakeholder meeting, has been heartened by a report, also out today, from the Efra select committee on badgers and cattle TB which says the Government is playing down the serious nature of bovine TB. In its response the committee, chaired by the Rt Hon Michael Jack MP, says:
NFU Deputy President Meurig Raymond said: “The industry feels let down and angered by the Government’s abdication of responsibility around this devastating disease. We have been left with no choice but to walk away from any attempt by Government to validate their ‘policy’ decision and pass responsibility for controlling this disease to the already beleaguered cattle sector. The Efra committee’s report reinforces both the fact that the Government has made the wrong decision and the need for something to be done now rather than waiting for vaccines to become available years down the line which will be too late for many farmers whose businesses are being decimated by this disease. The Efra report recognises the value of the VLA9 culling proposal put together by the NFU and other industry bodies for the South West of England. Hilary Benn has been invited to meet the people involved with VLA9 but has declined to do so which, given the hard work that has been put in on the plan, is very disappointing.”
The Farm Animal Welfare Council (FAWC) has launched its "Report on the implications of castration and tail docking for the welfare of lambs".
The report considers the implications of castration and tail docking for the welfare of lambs and reiterates FAWC's earlier view that castration and tail docking of lambs are mutilations which should not be undertaken without strong justification.
Professor Wathes, Chairman of FAWC, said: "FAWC believes that scientifically based advice can now be given that will minimise the suffering arising from castration and tail docking."
He continued "If castration is warranted, some methods cause more suffering than others and pain relief should be given once practical methods of delivering local anaesthetics and analgesics have been developed."
