The company is now asking farm vets to point their clients in the direction of the FarmComm study and encourage them to take part, share their thoughts and help shape the way we all work together in the future.
Mat Yarnall, senior brand manager at Boehringer said: "With routine visits, practice meetings, herd or flock health planning sessions and farming shows and exhibitions all on-hold, how vets work with their clients is subject to change on a scale never seen before.
“The study is striving to understand what methods of working going forward may work, what won’t work and how people want to work.”
The FarmComm study will be being sent out directly to farmers or can be accessed at https://bit.ly/farm-comm.
Matt added: "Following analysis and interpretation, these findings will be shared with vets as we all move together into new and different times."
Roy Geary, regional director for Northern Europe (including the UK) at Ceva Animal Health, said: “The manufacturing of vaccines is a complex process that involves stringent quality control measures and adherence to regulatory guidelines.
"Unfortunately, the anticipated vaccine batch has failed to meet the quality expected to be suitable for release, which has temporarily affected the ability to meet the demands of the UK sheep market within the main seasonal vaccination period for EAE."
“We anticipate that the issue in supply will be resolved, with some stock potentially available later in the season, however we recognise that for some farmers the supply will arrive too late for them to use.
"We are encouraging vets to explore alternative means of safeguarding the health of their clients’ flocks during this period.
"We recommend implementing robust biosecurity measures and adhering to existing vaccination protocols for other preventable diseases to ensure the overall wellbeing of livestock.
“We will provide vet practices and the wider industry with regular updates as we progress toward a resolution and return to normal supply levels.”
At the start of June, the British Veterinary Association (BVA), British Cattle Veterinary Association (BCVA), Goat Veterinary Society (GVS), and Sheep Veterinary Society (SVS) welcomed the announcement that bluetongue (BTV-8) vaccine would be available by mid-July to support farmers and smallholders in managing the risk of a bluetongue outbreak predicted to reach mainland UK by late summer.
Since the Defra risk assessment indicates a high risk by late summer of a BTV incursion from France, veterinary associations have been involved in discussions with government, farmers’ representatives and manufacturers to ensure vaccine is available to meet potential demand particularly in the south of England where risk is highest. The situation remains under constant review by Defra as the disease develops and the weather warms up, promoting midge activity.
Pharmaceutical companies MSD and Zoetis announced that batches of vaccine would be available from mid-July, which Defra has just confirmed.
Vets across the UK are also contributing to the Joint campaign Against Bluetongue (JAB), helping to make farmers aware of the risk, clinical signs and what action to take, through speaking at local JAB information events and displaying posters and leaflets in practices.
While welcoming the announcement of vaccine availability in June, veterinary organisations also sought clarification about the cost and the amount of vaccine likely to be available in July and thereafter. This information is now available.
BVA President Sean Wensley said: "We welcome the announcement that vaccine will be available in time to meet potential demand. This disease seriously affects animal health and welfare as well as the productivity of livestock, and vaccination is the key control."

The role was created last November when the Animal & Plant Health Agency (APHA) started allowing para-professional staff to support vets in carrying out TB testing in England.
UK Farmcare says there are now 49 fully authorised ATTs in England with another 21 TB testing under veterinary supervision and three undergoing the theory part of the training.
To become an ATT, applicants must be at least 18 years old, hold a valid UK driving licence and passport, possess a clean criminal record and then be approved by the APHA. Applicants also need at least three graded GCSEs or equivalent in English, Maths and a science or food production subject and at least six months cattle handling experience.

MSD says Lawsonia intracellularis is found on many finishing farms throughout the UK, and can affect weight gains, feed conversion ratios (FCR) and lead to increased mortality.
The new vaccine means that if piglets are vaccinated at three weeks, they will be protected against the bacteria from seven weeks.
Rubén Del Pozo Sacristán, technical manager for pigs at MSD Animal Health, said "Lawsonia intracellularis is present on most UK farms and can hamper a farm’s true potential as it spreads rapidly in faeces and on people or rodents, but symptoms can be hard to identify, as they’re often similar to many other diseases.
"Acute forms are often noticeable with symptoms such as diarrhoea or an increase in mortality, but the subclinical form, which is most common, can be hard to identify. Diarrhoea is not always present and often indicators are an increase in FCR and a reduction in weight gain leading to variation in pig performance, but this is similar to many other health issues.
"Administering an intramuscular vaccination will ensure every animal receives the correct dose, compared to other administrative routes. Porcilis Lawsonia can help reduce the clinical signs, production losses and mortality caused by Ileitis."
For more information on Porcilis Lawsonia, refer to the SPC sheet.
Mr Bowles faced four charges, but did not respond to the College's notification about the hearing, so the Committee decided to proceed in his absence.
The first charge was that in 2020, while attending a farm in Lincolnshire in his capacity as an Official Veterinarian (OV), Mr Bowles carried out Intradermal Comparative Tuberculin (ICT) tests on a herd of cattle but failed to measure the skin thickness of all the cattle using callipers and failed to take and record measurements for the cattle.
The Committee was provided with evidence that Mr Bowles had, in earlier correspondence with the College, admitted that he had failed to follow Animal and Plant Health Agency (APHA) standard operating procedures for ICT testing at the farm and so the charge was found proven.
The second charge was that he then certified the results of the inaccurate ICT test he'd performed earlier.
The Committee found this charge proven on the basis that, without using callipers to measure skin thickness, he was not entitled to certify the test.
The third charge was that his conduct in relation to the first two charges was dishonest, misleading and risked undermining government testing procedures designed to promote public health and animal welfare.
The Committee found all elements of the charges proven.
The final charge was that Mr Bowles's conduct took place despite warnings, advice and re-training being given by the APHA.
These included: a letter sent to Mr Bowles’s by APHA in 2014 about the suspension of his OV status after he failed to comply with APHA rules; a letter sent by the APHA to Mr Bowles’s employer in October 2016 regarding issues of non-compliance it had found during a September 2016 audit; and the suspension of Mr Bowles’s OV duties by his employer, pending further training, following issues of non-compliance.
Given Mr Bowles’s history of non-compliance with APHA standard operating procedures and standards, the Committee found the charge proven.
The Committee found that charges 1 to 3 amounted to serious professional misconduct but that charge 4, while making the conduct in the other charges more serious, did not in and of itself constitute serious professional misconduct.
In determining the most appropriate sanction for Mr Bowles, the Committee found that he had paid ‘scant regard’ to the testing procedures set out by APHA and breached the RCVS certification requirements set out in the Code of Professional Conduct for Veterinary Surgeons in ‘numerous and serious’ ways.
Hilary Lloyd, chairing the Committee and speaking on its behalf, said: “The Committee’s view is that the respondent’s conduct in refusing to follow the OV Instructions when testing cattle in May 2020 constituted conduct of an egregious kind.
"In addition, there are several aggravating elements which can be applied to his misconduct, including a risk to animal or human health; his lack of probity and integrity in certifying test results which he knew were non-compliant and unreliable; recklessness in reaching a conscious decision to ignore the OV Instructions; his failure to comply with the requirements of the position of trust and responsibility which attached to his APHA authorisation; and against a backdrop of sustained pattern of behaviour that displayed blatant disregard of the system that regulated TB testing by OVs.
"It follows that the respondent manifested no insight into the seriousness of his misconduct when acting as an OV.”
The Committee considered whether there were any mitigating factors regarding Mr Bowles’ conduct.
It took into account that Mr Bowles had not secured any financial advantage, that there was no actual harm to animals, and that he had a long career as a veterinary surgeon, although with a history of non-compliance.
It noted that there had been some late admissions of misconduct by Mr Bowles when he tendered an apology, but found this mitigation was undermined by the fact his explanations lacked consistency and that he had also initially asserted that he had used callipers during the testing.
Due to the seriousness of the non-compliance, the dishonesty and the potential risk to public health, the Committee considered that removing Mr Bowles from the Register was the only proportionate and appropriate response to the scale of misconduct.
Hilary added: “Given the amount of advice received and re-training which the respondent was required to undertake, he has already had ample opportunity to remediate his practice but has not done so.
"The Committee is therefore concerned that there is a very real risk of further repetition of this conduct in the future were he to be permitted to remain on the Register.
“The Committee’s concern in this regard stems from the fact that the dishonesty of which the respondent has been found guilty, was not dishonesty committed on the spur of the moment.
"The respondent had ample opportunities for reflection before resolving to act as he did.
"This places his acts of dishonesty in the most serious category.
“The public is entitled to expect that it can have confidence in the certifications of a veterinary surgeon who is carrying out a public duty on behalf of that public body.
"Indeed, that is the whole purpose behind the requirement that OVs undertake additional and specialised training before being permitted to undertake OV duties.”

Disbudding of Kid Goats The Goat Veterinary Society (GVS) has produced a DVD designed to help veterinary surgeons to disbud goats. Produced in association with the BVA Animal Welfare Foundation the DVD is in memory of the late Mike Teale MRCVS, following a donation from his family. The DVD discusses the potential problems associated with disbudding kid goats and provides guidance on how to avoid them. It shows the best technique for disbudding from start to finish and discusses anatomical considerations, methods of anaesthesia and analgesia and disbudding, with particular attention drawn to the regulatory aspects as they currently apply in the UK. For further information on the GVS DVD, including obtaining a copy, at a cost of £10, please visit http://www.bva-awf.org.uk/headlines/news/Disbudding_of_kid_goats_DVD__2_.pdf.
Bat Care Guidelines - a Guide to Bat Care for RehabilitatorsThe Bat Conservation Trust (BCT) has produced Bat Care Guidelines, in association with the BVA AWF, RSPCA and RCVS Trust, aimed at veterinary professionals, wildlife hospitals and new rehabilitators. The document is split into basic sections including 'health and safety', 'rescue and collection' and 'ailments and treatments' which aim to provide minimum guidelines for bat care. The new initiative is part of an ongoing partnership focusing on the rehabilitation of wild bats in the UK.

Leading industry experts including Faye Murch from Kingsgate Nutrition, Eric Nadeau, Elanco Global Pig Vaccine Advisor, veterinary consultant Daniel Parker and Francesc Molist from Schothorst Feed Research will share their learnings on alternative approaches to managing PWD, including vaccination.
Jack Fellows from Elanco Animal Health says that with 90% of producers using their vet as their first port of call when it comes to PWD1, it is vital they start to encourage producers to consider an alternative prescription to zinc.
He said: “Producers must start to prepare now to avoid being forced to turn to antibiotics when zinc is no longer an option.
"Vaccination will become an increasingly important component of PWD prevention. Amongst other topics on mastering piglet gut health, the seminar aims to support knowledge on the application of in-water vaccines to ensure appropriate and effective use.”
Jack says that while vaccination may appear costly in comparison to zinc oxide, it offers a good return on investment: "Piglets can be vaccinated from 18 days of life, so they are protected from the pathogen at weaning, and we are seeing a growing number of UK herds using vaccines as part of their PWD prevention strategy.
"Farms using the Coliprotec vaccine are no longer using in-water medication to control scours. They’re also noticing that piglets are eating more, and that they’re achieving an extra 2kg of slaughter weight2 while reaching market weights seven days sooner3.”

Hysolv Animal Health UK has announced that it is offering a free diagnostic test which allows vets to identify the E. coli sub-types that produce the Shiga toxin associated with oedema disease in pigs.
The test, known as STEC-Check and worth £150-£200, is being sponsored by IDT Biologika GmbH. In the UK and Republic of Ireland, faeces and/or intestinal samples will be sent to the Animal Health and Plant Agency (APHA), Weybridge and SAC Consulting Veterinary Services at Penicuik to confirm results within a few days.
Hysolv says the test will provide a quick and accurate diagnosis, enabling appropriate action, including vaccination, to be taken on the farm.
Richard Brealey from Hysolv said: "Oedema disease is not always obvious and may be masked or controlled by the use of antibiotics, the use of zinc oxide or low-protein feeds which can also negatively affect productivity. This test will help confirm the presence of Shiga-toxin producing E. coli on the farm, a cause of serious losses in individual herds. We are therefore advising farmers to contact their vets to discuss using STEC-check on their farms."
According to the company, a nationwide study in Germany showed that 59% of farms where oedema was suspected were affected by Shiga toxin.
Richard added: "The Ecoporc Shiga vaccine has been recently licensed for use in the UK. There is pressure on vets and farmers to reduce the use of antimicrobials and vaccination, together with other measures, and this will help them to do this."
In the UK farmers will be able to carry out a DIY calculation of their return on investment online, using their smartphones or by visiting the Shiga toxin website www.shigatoxin.com
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.”
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."
Janssen Animal Health has released the results of a survey which suggests incorrect worming strategies on many pig units in the UK are costing the industry dearly.
Most state they do not worm weaners, growers or finishing pigs at all and, while most sows are wormed, only a third treat newly-arrived gilts and boars in quarantine.
Phil Macdonald, UK and Ireland pig business manager at Janssen said: "Worm infestations can harm growth rate and feed efficiency, they can reduce abattoir returns and increase the cost of medication".
According to the company, the survey responses point to confusion among some producers on what constitutes a strategic worming programme. Most, 68 per cent, state they have implemented strategic programmes, but fewer than two-thirds of these cover all pigs on a unit and even fewer correctly base their programmes on the pre-patent period of worms.
Phil said: "It's important that all pigs on a unit are covered by the programme, otherwise there is a higher potential for reinfection. To be effective, the anthelmintic treatment periods need to be based on the pre-patent period of worms, so that treatment interrupts their life cycle.
"It requires a strategic worming programme with a broad spectrum anthelmintic such as Flubenol and Solubenol 100mg/g, which is the first and only water-soluble benzimidazole in the market. These are effective against larvae and worm eggs of a number of worm species as well as the large roundworm, Ascaris suum. Migrating larvae of the large roundworm cause Milk Spot lesions in pig livers, which are damaging to animal welfare and unit economics."
The make-up of UK units in the survey was 58 per cent breeder/finisher, 39 per cent finisher, 3 per cent weaner/finisher. Most, 68 per cent, use dry pelleted feed, 16 per cent wet feed and 16 per cent have both feed systems.
There is wide variation in worming programmes among producers. Most breeders worm their sows - 17 per cent once a year, 56 per cent twice and 11 per cent three times. With boars, 28 per cent worm them once a year, 44 per cent twice and 11 per cent three times. But only one-third (34 per cent) of breeders worm newly-arrived gilts and boars in quarantine.
72 per cent of producers with breeding sows who responded do not worm weaners and 80 per cent do not worm growers. Of the total responses, including specialist finishers, 68 per cent do not worm finishing pigs.
Most producers, 81 per cent, stated that they are aware that livers with Milk Spot lesions have to be trimmed or totally condemned, adding significant annual costs for disposal.
68 per cent admit to Milk Spot lesion levels of 25 per cent in consignments of pigs. Another 10 per cent experience up to 75 per cent livers with Milk Spot damage, and 3 per cent have had every pig liver in a consignment trimmed or condemned because of lesions. The feedback to producers comes from the BPEX Pig Health Scheme, of which 88 per cent of producers are members.
Only 58 per cent of producers are aware that more traditional worming methods allow pigs continuously to reinfect each other and their environment. Traditional programmes do not take the worm's life cycle into account.
The detrimental effect of worm damage that causes most concern to producers is lost growth/poorer feed conversion (29 per cent). Others considered the most important to be:
Phil says research shows that losses in daily liveweight gain alone add up to £2.31 per slaughter pig where liver condemnations are 30 per cent. "The frightening fact is that the loss is for every slaughter pig, not just those with Milk Spot lesions.
"In a 300-sow herd producing 23 pigs per sow per year that's a loss of £15,939 a year. On a 1,000-sow unit that exceeds a horrendous £53,000 annually, and these figures take no account of other areas of loss mentioned."
An adult female worm can shed hundreds of thousands of eggs each day, which pigs pass out in their dung. Worm eggs can remain infective for up to 10 years. Other pigs ingest them and the reinfection process begins.
Phil said: "A strategic worming programme that treats all pigs on a unit simultaneously is the only effective way to almost completely eliminate the problem. The survey has shown there is considerable potential for a large proportion of producers to improve productivity and cut costs by focusing on this critical area of management."
Lohmann Animal Health has launched AviPro IBD Xtreme vaccine against Infectious Bursal Disease — also known as Gumboro Disease — in broilers, commercial layers and breeders.
According to Lohmannn, it is highly effective against the vvIBDV (very virulent IBD virus), it breaks through high levels of maternal antibodies, and controls mortality with no loss of flock performance.
Since the 1980s the acute form of IBD has caused significant economic loss to the poultry industries in several countries. The vvIBDV, a more aggressive form first described in Europe in 1986, is now widespread throughout the world and can cause losses of 30-60 per cent in layers and 5-25 per cent in broilers.
Chicks are most susceptible between one and six weeks. Early in their lives they are protected by maternally-derived antibodies (MDAs), but these antibodies will neutralise live IBD vaccines when they are given too early. However, being highly invasive, the AviPro IBD Xtreme vaccine is able to overcome these MDAs so can be given earlier to provide greater protection from an early age.
Exact timing of vaccination depends primarily on the level of MDAs and the breakthrough titre of the vaccine on the one hand, and the virulence of the field virus and infection pressure on the other.
When compared with four of its main competitors in a trial with SPF birds AviPro IBD Xtreme outperformed them. It had the highest number of sero-positive birds, the highest mean ELISA-antibody titre seven days after vaccination and the best protection against clinical symptoms and mortality after a challenge with vvIBDV,” commented Brigitte Othmar, regulatory affairs manager at LAH.
“With the addition of AviPro IBD Xtreme, Lohmann Animal Health has now completed its range of live IBD vaccines and is able to provide its customers with the appropriate solution for any Gumboro problem,” she added.
AviPro IBD Xtreme can be applied via the drinking water or eye-drop and is presented in vials of 1,000 and 2,500 doses.
More information on this vaccine can be found on the Lohmann Animal Health website http://www.lah.de/.
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.

The research will specifically focus on Mycoplasma hyopneumoniae (M.hyop), the causative agent of the disease, and aim to progress vaccine development.
Zoetis has stumped up another £300K in kind to support the research.
M.hyop is present in 80% of UK pig herds, which can result in a 16% reduction of growth and a 14% reduction in feed conversion in pigs.
This therefore, is not only a welfare issue for pigs but can significantly increase production costs for farmers.
Piglets are at particular risk of contracting the disease alongside secondary pathogens during lactation.
There are currently no commercial vaccines available that would prevent initial infection, and while M.hyop is susceptible to a variety of antibiotics, their use needs to be reduced to avoid overuse and the occurrence of multi-drug resistant strains.
The priority for the RVC researchers will therefore be developing new vaccines.
The team will also research the optimisation of protocols to eliminate M.hyop from pig herds in an effort to further minimise potential transmission.
Professor Dirk Werling, Professor of Molecular Immunology at the RVC, said: “Infection of Mycoplasma hyopneumoniae is a really debilitating disease in pigs that causes huge economic losses for farmers.
"I am very pleased that we will be able to continue working with a pharmaceutical partner to develop a new vaccine using state-of the-art technologies.”
Following stock challenges earlier in the year, the company is now urging vets to encourage farmers to vaccinate their flocks to prevent abortions during lambing.
Roy Geary, regional director for Northern Europe at Ceva Animal Health, said: “While we realise that the temporary delay of Cevac Chlamydia has been inconvenient to our valued sheep farmers we would like to thank all our customers for their patience and support during this challenging time.
"The vaccine supply is now available in the UK for the latter end of the season.
"Farmers tupping later in October should therefore be encouraged to vaccinate their flocks to protect their ewes from this devastating disease.”

Scientists at the Royal Veterinary College, contributing to a programme to tackle some of the most harmful and widespread endemic diseases that commonly affect farmed animals in the UK, have developed a severity estimation calculator for post-weaning multi-systemic wasting syndrome (PMWS).
Post-weaning multi-systemic wasting syndrome (PMWS) is a common disease of young pigs in the U.K. It is extremely debilitating, causes considerable suffering and poor welfare, and has a high mortality of up to 30%. It is estimated that the disease costs the UK farming industry £30m per year.
The £2.4m project - headed by Professor Dirk Werling from the Royal Veterinary College and funded by the Biotechnology and Biological Sciences Research Council (BBSRC) through its "Combating Endemic Diseases For Farm-Animal Sustainability" programme (CEDFAS), the British Pig Executive (BPEX), and two industrial partners, Pfizer Ltd (UK) and BioBest - aims to identify why PMWS occurs and to develop new methods of controlling the disease.
One key-component of the project is the direct involvement of British pig farmers, thereby guaranteeing that pigs in Britain will be the first to benefit from this research, while collaboration with a major international pharmaceutical company will ensure that new veterinary products will be made available to pig farmers worldwide.
Now, two members of the team, Dr. Barbara Wieland and Pablo Alarcon-Lopez, a second year PhD student, have developed a novel approach to quantify severity of PMWS based on morbidity and mortality data and presence of porcine circovirus type 2 (PCV2). They applied factorial analyses, using data collected from 147 pig farms in England to identify variables contributing to variation in PMWS severity in a biologically meaningful way.
Together with other known variables linked to PMWS, the resulting factors were used to derive an algorithm for PMWS severity. The derived algorithm was used to develop a PMWS severity calculator, which now can be used by farmers directly to assess the PMWS severity on their own farm (http://www.bpex.org.uk/articles/300874).
The levels of PMWS severities identified on farm level can now be used to identify risk factors related to the different severity-categories, to assess the efficacy of PCV2 vaccination and to investigate the economic impact of potential control measures on a farm.
The Veterinary Laboratories Agency has worked in collaboration with the Institute of Animal Health (IAH) at Pirbright to introduce the Polymerase Chain Reaction (PCR) test for Bluetongue virus.
This test is now available via veterinary surgeons for pre-movement (UK) and export testing purposes only.
As of this date, PCR testing for these purposes will no longer be available from IAH, Pirbright.

“Livestock and Climate Change - A Veterinary Perspective” is an online learning course designed to give vets the confidence to make changes in their own work and the tools to support farming clients in meeting their goals.
It includes modules such as ‘Introduction to Sustainability for Veterinary Professionals’, ‘Emissions from Livestock Production’, ‘Housed Livestock Systems - Welfare, Nutrition and Emissions’, ‘Impact of Disease State on Greenhouse Gas Emissions from Livestock’ and ‘Advantages and Trade-offs of Grazing Systems in Mitigating Climate Change’.
The 6-module course is expected to take up to 3 months to complete (equivalent to 15 hours of CPD) by remote learning, and participants will get a LANTRA-accredited certificate on completion.
Lewis Griffiths, Chair of VetSalus, said “The veterinary profession has always had a critical role to play in technology transfer and the development of new farming systems.
"This course will equip vets to assist their farm clients in the incredibly important work of adapting to more sustainable production.
"I believe this is one of the most important courses to be developed for farm based veterinarians in recent years.”
Rune Friis Kristensen, Managing Director of Dyrlæger & Ko, Executive Officer at VetSalus and module champion said of the course “Livestock vets play an important role in the discussion around/about sustainability.
"Whether it is discussion with farmers, colleagues, academia or future vets it is pivotal that livestock vets know what they talk about when addressing emission issues.
"We know from surveys that the key decision maker when it comes to animal health and robustness is the vet, and more robust animals are always more sustainable.
"This course will provide learners with the knowledge that without a doubt is expected of vets in 2024.”
The course is aimed at veterinary professionals and those working in vet-led businesses, and whilst there are no specific entry requirements, all students are expected to have undertaken an undergraduate degree, technical qualification as a paraprofessional, or a relevant diploma.
The course costs £495 +VAT per student (registered overseas businesses may be eligible for a VAT exclusive price).

The new award, sponsored by Krka UK, will recognise an exceptional farm vet who has been working in the dairy industry for three to five years and who has contributed significantly to the health and wellbeing of herds under their care.
Sarah Tomlinson, veterinary surgeon at Westpoint Farm Vets in Derbyshire, Technical Director of the TB Advisory Service (TBAS) and recipient of the 2020 Dairy Vet of the Year, said: “In recognising achievement among more recently qualified vets with this new award, Krka is giving the boost every young vet needs to shake off the ‘new grad’ title and instead become an ‘high performing’ vet, judged by their industry peers to be one of the best. Many vets can suffer with imposter syndrome so it is important that we accept positive acknowledgement of our work and our everyday achievements so that we can be rightly proud of what we do.”
