The new 'SMART goals tool' is an addition to the charity's Farm Vet Champions programme, which supports veterinary teams with knowledge and resources to ensure antimicrobials are used responsibly.
To support the take-up of the new SMART goals tool, RCVS Knowledge will be running a free webinar on Zoom at 12:30pm on Tuesday 17th May (register here).
Fiona Lovatt, Farm Vet Champions Clinical Lead, said: “It is such a critical time to ensure we are using antimicrobials responsibly so that they will work when patients really need them.
"We all have a responsibility to fight antimicrobial resistance. The good news is there is a lot we can do – one of those things is getting involved with Farm Vet Champions, enhancing our skills and adapting our practice.
“I am so excited to see the launch of our SMART goal tool. It is both engaging and simple to use, and I expect it will encourage practice teams to motivate each other to track their progress in their stewardship activities.
Fraser Broadfoot, Head of Antibiotic Use and Stewardship Team at Veterinary Medicines Directorate, said: “We are really supportive of this important initiative.
"In the UK we have seen a 52% reduction in antibiotic use for food producing animals since 2014, and this has been driven by vets and farmers working together to reduce unnecessary use of antibiotics and with a strong focus on disease prevention.
"However, as highlighted in the RUMA sector targets, there are still areas where improvements can be made and where antibiotic use data is lacking.
"This SMART goals tool therefore provides an easy-to-use and practical resource that is designed to help and motivate vets and practice teams to set, monitor and accomplish goals and build on the tremendous progress that they have already achieved.
"This will not only help the livestock sectors to achieve their targets, but will result in improvements in animal health and, by reducing the burden of resistant bacteria, have public health benefits too.”
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."
The award, introduced in 2020 and supported by animal health company Krka UK, recognises 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.
The winner of the first award, in 2021, was Rob Hall from LLM Farm Vets in Shropshire. He said: "The sustainability of the dairy industry will remain in the spotlight for decades to come with young vets in a great position to work with dairy farmers of the future to improve the efficiency of their herds. This can be achieved, for instance, by improving nutrition, genetics and housing; by helping farmers to reduce antibiotics or wormers; and by reducing the detrimental effects of disease.”
He added: “As vets start their post-university careers, they face a steep learning curve. Dairy vets, in particular, have a huge arsenal of practical skills to hone, as well as trying to forge relationships with farmers and colleagues. It can be tricky to strike the right balance, while finding time to pursue their own interests to keep work interesting. I’ve been lucky at LLM to have had the opportunity to work with a great team and engaged farmers. This has enabled me to pick up the basics, as well as being able to delve deeper into the aspects of farming which interest me most. I’m extremely grateful to The Cream Awards for recognising this and to KRKA for its support of the Young Dairy Vet Award.”
Charlotte Read (pictured right), Krka Key Account Manager – Farm, added: “Krka is proud to support the recognition of rising stars within the dairy veterinary profession and hope that their achievements will inspire many of the next generation of veterinary surgeons to embrace the rewarding life of the farm vet.”

Intervet/Schering-Plough has announced that the license for Leptavoid-H has been improved allowing concurrent use with Bovilis BVD.
Intervet/Schering Plough says that given both vaccines are typically administered in the busy pre-turnout period, this will ease on-farm workload and should help to ensure that all primary courses or boosters take place sufficiently in advance of the period of risk.
Each vaccine is to be given by separate routes and sites, to animals of 8 months or older. The concurrent use in cattle may result in fewer animal interventions, less stress and better welfare.
The studies, undertaken by Intervet/Schering Plough's R&D division in the UK, focussed on both the safety and efficacy aspects of the concurrent administration of Leptavoid-H with Bovilis BVD. The company says no systemic adverse events occurred, there was no effect on the outcome of pregnancy or milk yields and the efficacy in cattle was not compromised.
Leptavoid-H is licensed to reduce the shedding of Leptospira interrogans serovar hardjo in urine. Leptavoid-H is the only Leptospirosis vaccine licensed to improve herd fertility when Leptospira hardjo is the cause of herd infertility, and the only vaccine proven to protect stock against both strains in the UK.
Guidelines on the examination of rams for breeding have now been officially updated, thanks to the pooled expertise of delegates at a recent Sheep Fertility Workshop, sponsored by Ceva Animal Health, the Sheep Veterinary Society and EBLEX-AHDB.The previous Sheep Veterinary Society guidelines on the examination of rams for breeding were drawn up in 2007. However, the society says that to date, there has been considerable variation in the practice of ram fertility testing amongst sheep vets across the country.
The Sheep Fertility Workshop, which was held in Edinburgh in June 1014, brought together veterinary experts and scientists to discuss the provision of a comprehensive, evidence-based, best practice protocol, with clear recommendations for practitioners on the assessment of rams.Dr Fiona Lovatt, senior vice president of the Sheep Veterinary Society and director of Flock Health Ltd, who coordinated the workshop, said: "The outcome of some active debating was the recognition that various elements of the guidelines needed to be updated in line with currently recognised best practice. One thing that is really essential is that the practising vet is clear as to the reason for the ram PBE and carefully considers how to communicate the findings and their limitations to the ram's owner."
The updated guidelines cover three levels of ram pre-breeding examinations (PBE):
Carol Atkinson, Ceva's reprodAction range marketing manager, said: "We are proud to have supported the workshop, the outcome of which has been some valuable modifications to the guidelines. We now have a robust, practical benchmarking system in place to help ensure consistency of ram fertility and flock health and development."
The workshop was funded by the Sheep Veterinary Society, Ceva Animal Health and EBLEX-AHDB, with contributions in kind from Innovis, Zoetis and Novartis Animal Health.
The guidelines are available to all members of the Sheep Veterinary Society and can be downloaded from www.sheepvetsoc.org.uk, together with two further forms that are available following appropriate training: SVS Ram PBE data collection and SVS Ram certificate. The Sheep Veterinary Society will be holding a series of CPD days for practitioners in advance of next year's breeding season. Further details will be posted on the website shortly.
BovIntel is software which, alongside the company's Easi-Scan:Go bovine ultrasound scanner, automatically identifies and measures important features on ultrasound images in real time as a vet carries out a scan.
The software uses colour to highlight and label structures such as follicles and corpus luteums, displaying the measurements of these to the nearest millimetre.
The technology has been designed to make the fertility scanning process easier and more accurate, helping vets give more informed breeding advice.
The developers behind BovIntel say the information that it provides will improve pregnancy rates and therefore overall productivity of dairy herds.
Alan Picken, Imaging Innovation Director said: “Pregnancy rates are notoriously low in the US and across Europe with as few as one in three inseminations producing a pregnancy.
"This is costing the industry time and money.
“Diagnostics on ovarian health is only possible through ultrasound and veterinary assessment, but not all vets are offering this service to their clients.
"BovIntel makes this ultrasound information more accessible to vets, and vastly increases the value and efficacy of the advice they provide to clients.
“Essentially, it enables a vet to quickly and accurately assess the ovarian health of a cow, so they can advise on how to achieve conception at the earliest opportunity.
"Equally, it allows them to quickly establish if a cow is unlikely to get pregnant and prevent a wasted insemination.”
IMV Technologies says new technology also promises to reduce the fertility scanning training time of newly qualified vets, by helping them to quickly find the ovaries during a scan and giving them confidence in interpreting ultrasound images.
Aland added “New vets will be able to practice independently faster and need the support of senior vets for less time, both of which brings huge benefits to their confidence and professional development and to the productivity of the business.”
IMV says the technology will also be useful for universities and research organisations investigating dairy cow reproductive health.
BovIntel is a software addition to IMV’s Go:Scan app.
It can be used via the viewing app, but also with BUG headsets, augmenting in colour for VGA and colour OLED. For users with mono BUG:Go headsets it will appear as grayscale on the headset screen, but in colour on the viewing app.
There's a 30-day free trial of the software for vets using the Go:Scan app, after which there is a choice of a subscription or pay-as-you-scan.
Norbrook Laboratories has launched Cefimam DC intramammary ointment, a new dry cow preparation containing the 4th generation cephalosporin, cefquinome.
The company has also released a Polish language version of its Best Practice Guide for On-Farm Mastitis Control, in response to demand from producers with non-English speaking farm-hands.
Norbrook vet Chris Geddes said: "I believe this is the first time that such a guide has been produced to cater for farm-hands of a different nationality working within the UK. Good mastitis management starts with good education; giving everyone on the farm the same opportunity for learning the best techniques for prevention means that we help minimise incidences of mastitis, which costs the dairy industry millions of pounds in lost revenue every year.
"This prevention includes a thorough and consistent approach to dry cow management. The early drying off period is often a risky time, when pre-existing subclinical infections can bed-in. The cow is also at increased risk of gaining new infections due to lack of udder hygiene procedures that would normally occur at milking, and weakened immunity as she approaches calving. Our new cefquinome preparation is a valuable addition to have in the treatment armoury for dry cow management. It has broad-spectrum activity and high cellular penetration to help tackle hard-to-manage cases with the aim of returning to maximum productivity by the start of the milking season."
Cefimam DC will be available at all veterinary wholesalers in packs of 24x and 120x 8g intramammary tubes. Vets can obtain both English and Polish versions of the Best Practice Guide for On-Farm Mastitis Control from Territory Managers.
For further information or copies of the Best Practice Guide for On-Farm Mastitis Control in English or Polish, contact your Territory Manager or call Norbrook GB head office on 01536 741 147.
Grahame Gardner has introduced the M559, a classically styled tunic, stocked for the first time in bottle green.
The company says that although it has sold numerous ladies tunics in bottle green, this is the first time it has stocked a male tunic in the characteristic veterinary colour.
The M559 incorporates side fastening with the option of contrasting epaulettes, alongside practical pockets and side slits.
Simon Ward, Sales Director said: "We are delighted to introduce this new garment to the veterinary market. We are continually reviewing our range in response to customer comments, and felt it was time we stocked a bottle green option, specifically for male members of the veterinary team."
Stocked in sizes from 34" to 50" (chest), the M559 is just one of several new styles introduced in Grahame Gardner's latest brochure. The company is also launching a new men's scrub tunic. The SS3295 has a v style neck, complemented by the v-detail on the sleeves, and contrasting trim available on the neck, sleeve and pocket. Also stocked in bottle green, the company says this tunic is aimed at veterinary professionals who prefer a more relaxed approach to uniforms.
To explore Grahame Gardner's collection please take a look at http://www.grahamegardner.co.uk/, or call 0116 255 6326 to order a copy of their new brochure.
From today, porcine epidemic diarrhoea (PED) is a notifiable disease in England; veterinary surgeons and pig-keepers are now legally required to inform the Animal and Plant Health Agency of any suspicion of the disease.
If a test for PED proves positive, the Government will inform AHDB Pork, so that tracing can be carried out and improved biosecurity measures put in place.
The new measure has been introduced following co-operation between Defra APHA, AHDB Pork, the NPA and other industry bodies. Although PED is now classified as notifiable, there will be no statutory movement controls, no compulsory slaughter and no blocks on exports.
Under the new legislation in England, APHA will be legally permitted to inform AHDB Pork - which is the agreed 'appropriate organisation' - in confidence of suspect and confirmed cases. AHDB Pork will then provide biosecurity guidance to the pig unit concerned. It will also carry out tracing and alert at-risk contacts as necessary.
The aim will be to prevent spread of PED and to eliminate the disease from the pig unit. There will be no requirement to slaughter affected animals.
PED has been made lightweight notifiable following an informal consultation process with the pig industry. NPA and others called for the measure so that any outbreak can be identified as quickly as possible, spread can be prevented, and the disease can then be eliminated from the unit concerned.
AHDB Pork Chairman Meryl Ward said: "This initiative is a significant step change in partnership working between industry, Defra and the APHA to build England’s resilience to disease.
"PED is a potentially serious disease and emerging threat to our English pig industry. A unique industry led collaboration with Government led to the development of the PEDv Contingency plan to ‘identify, contain and eliminate’.
"The regulatory change to notifiable status is a critical part of the plan and will assist in early identification of affected premises, allowing more time to take effective actions to minimise the impact on the industry and therefore increasing the opportunity to eliminate the disease.
"Working together to share resource, knowledge and build vital expertise, the partnership has also developed a series of standard operating procedures, bio- security guidance as well as raising awareness across industry of the potential threat.
PED remains a significant threat to British pig-keepers. According to AHDB, outbreaks of high-impact strains caused up to 100% mortality in young pigs in the United States, knocking out around 10% of pig production in 2013-2014. The disease has since spread to Ukraine. Even with milder European Union strains, piglet mortality as high as 70% has been reported.
The Scottish Government is currently consulting on making PED similarly lightweight notifiable in Scotland.
The BVA and the Pig Veterinary Society (PVS) have welcomed the announcement. John Blackwell, Senior Vice President of the British Veterinary Association, said: "From today pig-keepers will be required to contact APHA if they have any suspicion of PED in their livestock - this is a step in the right direction and a result of joined up working between the industry, the veterinary profession and policy makers. PED is a devastating disease and we hope these measures will be sufficient to protect animals and pig-keepers in England from future outbreaks. We are encouraged by current proposals to make PED notifiable in Scotland and are keen to see similar measures in place across the rest of the UK."
Dr Mandy Nevel, President of the Pig Veterinary Society, said: "The Pig Veterinary Society was actively involved in the decision to make PED notifiable in England and we fully support the decision. Whilst we hope PED does not come into England, the legislation will facilitate rapid diagnosis, control and eradication in the event of a case occurring. We urge the rest of the UK to take similar action."

The Veterinary Marketing Association has announced details of a new award for public relations, open to veterinary practices and companies.
The VMA says this award is to recognise the value that media and public relations can add to the marketing mix. It will be awarded to the company or veterinary practice that has delivered the most innovative PR campaign during 2011, as judged by a panel of industry professionals.
Organiser Claire Edmunds said: "The VMA Awards has become a coveted event for those involved in the animal health industry to showcase their marketing achievements. A range of categories has evolved since the awards began over 20 years ago, for marketing, creative communication and new media campaigns. However, we felt that an award for PR was required to complete the marketing mix".
Jane Manning from award sponsor Splash Marketing & Communications said: "We felt it was time to give the opportunity for those involved in PR to obtain the recognition they deserve alongside their creative colleagues.
"An effective PR campaign can be a highly influential marketing tool, so it's great news that the VMA has added this new award category. We hope that companies and agencies serving the animal health sector will embrace this new opportunity to showcase their creativity and hard work".
The award is for the most innovative PR initiative published during the year. This can be a single 'one-off' event or article, or a sustained campaign over a given period. The winner and two highly commended entries will be awarded at the VMA Awards on Friday 9th March 2012 at Shakespeare's UnderGlobe Theatre, London.
Further information on the awards and ticket application forms are available at the VMA's website - http://www.vma.org.uk/ or by calling 0844 561 6157. The deadline for entries is Friday 27th January 2012.
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.”

Eprinex Multi contains eprinomectin and is effective against the adult stages of the major gutworm species affecting sheep and goats, and the lungworm Dictyocaulus filaria.
Merial highlights two studies which show how treatment can overcome the productivity impact of a parasite burden. In the first, dairy ewes showed a significant increase in milk yield following treatment with Eprinex Multi compared to untreated animals.1
The second study, which looked at interactions between nutrition and gastrointestinal parasites in French dairy goats concluded that subclinical parasite infections induced a persistent decrease in milk yield, ranging from 2.5 to 10%.2
Sioned Timothy, Technical Manager, UK & ROI, Merial Animal Health said: "Merial recognises the need for sustainable, effective disease prevention strategies both to optimise the health and welfare of livestock, and to protect their productivity.
"The small dairy ruminant sector in the UK is small but growing: the registration of Eprinex Multi allows us to communicate and work with this industry to promote best practice in parasite control.
"Eprinex Multi brings a new active ingredient to the sheep and goat wormer market and provides vets and farmers with an additional tool to use alongside good management practices, as part of an integrated parasite control strategy.
"It has the advantage of zero milk withhold, which allows dairy animals to be treated at the optimal time without the concern of lost milk.
"Merial values this very important sector of the livestock industry and is excited to offer this new development to the marketplace. Eprinex Pour On has proven itself in the cattle sector over the last two decades, and the registration of Eprinex Multi with indications for use in goats and sheep alongside cattle offers new opportunities for managing animal health, welfare and production.
Hysolv says the vaccine, which was developed by IDT Biologika, has been used successfully in Germany, where 1.7 million doses have been prescribed. The company says field trials have shown that vaccination not only protected against clinical signs of influenza but also resulted in improvements in reproduction and piglet performance.
Two 1 ml doses of the inactivated vaccine can be injected intramuscularly three weeks apart to pigs from 56 days old, providing immunisation to the majority of animals within seven days.
Hysolv director, Geoff Hooper said: "Swine flu can be devastating to a herd and this vaccine will broaden protection, particularly when used with our existing vaccine Respiporc FLU3, which we are strongly advising."
Respiporc FLU3 protects against three other strains of swine flu (H1N1, H1N2 and H3N2). Hysolv says that when used together, the two vaccines protect pigs against the most relevant strains in the British Isles.
Geoff added: "There have been several flu pandemics throughout the years – the latest in 2009. It is not possible to predict the emergence of a pandemic strain accurately but this vaccine combined with Respiporc FLU3 will greatly decrease the chance of pigs becoming infected."
They say this approach could lead to a reduction in the number of vaccines that need to be administered to each bird.
Vaccines that target multiple diseases are in high demand due to the many viruses that can circulate simultaneously in flocks. Protecting against the most dangerous diseases with one vaccine could reduce overall vaccination costs for poultry producers and decrease the number of times that birds need to be handled.
The researchers demonstrated that a gene editing system called CRISPR/cas9 can be used to insert a gene of the IBD virus into the currently used Marek’s disease vaccine virus. The added genetic material protects poultry against IBD in addition to the protection already offered by the Marek’s disease vaccine, meaning that bird owners would only need to use one vaccine instead of two.
Other vaccines generated by conventional methods can achieve a similar result, but by using the CRISPR/cas9 system the Pirbright researchers say they have been able to insert the IBD gene far more quickly, easily and accurately than the methods that have been used before. This will significantly reduce the time needed to generate new vaccines.
Professor Venugopal Nair, joint leader of the research at Pirbright said: "The method we have created with CRISPR/cas9 really increases the scope of how we edit the Marek’s disease vaccine to include other virus components. Now we have shown that the gene-edited vaccine protects against both Marek’s disease and IBD, we are looking at inserting more genes from other viruses."
The team intend to generate a vaccine that will be able to protect against multiple avian diseases and will next target two high consequence poultry viruses - avian influenza virus and the Newcastle disease virus. The flexibility of the new method also means that as the viruses evolve, the vaccine virus can be easily edited to include new genes which protect against emerging strains.
The Pirbright Institute says there has been huge commercial interest in using this technology to develop novel vaccines, so it intends to partner vaccine manufacturing companies to bring CRISPR/cas9 edited vaccines to market.

BVA has announced that it is launching a pilot of VETS.TV, and invites you to come and preview the service at its stand at BSAVA. Anyone willing to surrender their name and email address will also be entered into a prize draw to win an HP 530 Celeron M 440 laptop computer.
VETS.TV is an internet television site run jointly by the BVA and Ten Alps Publishing which will be available via a microsite of http://www.bva.co.uk/. The pilot includes custom-made videos on MRSA, litigation and stress management, a series of interviews with key veterinary figures and a number of specially acquired programmes.
The change has come about following a review of the assurance scheme's standards, when it was decided that all Red Tractor vets should be members of PVS, not just those carrying out Real Welfare assessments, as was previously the case.
Other changes in the review focus on the responsible use of antibiotics and a number of the animal medicine standards have been strengthened.
Red Tractor says the PVS membership requirement is in line with another new standard which will require veterinary surgeons to declare they only prescribe antibiotics for use on Red Tractor pig units in accordance with the PVS Prescribing Principles for Antimicrobials.
Red Tractor technical manager Joanna King said: "Ensuring every Red Tractor registered vet is a PVS member will help keep them abreast of the most recent version of the Prescribing Principles, along with other guidelines and publications."
Assessors undertaking Red Tractor farm assessments can verify whether the retained farm vet is a current PVS member through their membership number which is required on the quarterly veterinary report forms.
Membership numbers can be checked against an online PVS membership checker.
The National Office of Animal Health (NOAH) has launched a new 'Use Medicines Responsibly' campaign.
The main thrust of the campaign is an initiative by NOAH to encourage pharmaceutical companies to add: 'Use Medicines Responsibly' as a strapline to their own advertising campaigns, with a link to the NOAH information resource for prescribers and users of animal medicines: www.noah.co.uk/responsible.
Speaking at the NOAH annual members' conference in Northampton, NOAH chief executive Phil Sketchley said: "NOAH believes responsible promotion of animal medicines to be an important link in the chain towards responsible use. Companies' promotional material can educate prescribers and users of animal medicines to the benefit of their animals' health and welfare.
"We believe this new advice resource, with the reminder on advertisements, will help."
