MSD Animal Health has obtained regulatory approval in 21 European countries, including the UK, for Cobactan LA 7.5% (cefquinome) - a new-generation, injectable antimicrobial for the treatment of swine respiratory disease (SRD).
Raul Berro DVM, global marketing director swine at MSD Animal Health said: "Cobactan LA 7.5% is a long-acting version of our highly effective Cobactan 2.5%. Its longer duration of action means greater compliance for swine producers with fewer injections and less stress to the animals, without sacrificing performance."
According to the company, the long-acting antibiotic formulation is effective against three major SRD pathogens in growing and finishing pigs - Actinobacillus pleuropneumoniae, Haemophilus parasuis and Pasteurella multocida. Considered the most important threat to the swine industry worldwide, SRD causes increased mortality, decreased weight gain and increased feed consumption.
Cobactan LA 7.5% requires two intramuscular injections 48 hours apart, compared to Cobactan 2.5%, which requires three daily injections. The recommended dose rate is 1 mL (3 mg cefquinome) per 25 kg bodyweight. The product isavailable in 50-ml, 100-ml and 250-ml glass vials.
Raul aded: "COBACTAN LA 7.5% also has a short withdrawal period of seven days. This makes the injectable product also safe to use throughout the finishing period for the treatment of SRD."
MSD adds that the use of COBACTAN LA 7.5% should be according to established responsible use guidelines and strictly according to the label instructions where specific restrictions apply to this class of antibiotics.

Bovilis Bovivac S is used for active immunisation to induce serological and colostral antibody production against Salmonella Dublin and Salmonella Typhimurium.
In the face of an outbreak, it can also be used to reduce Salmonella Typhimurium infections when used as part of an overall herd management programme.
MSD says Bovilis Bovivac S may also contribute to reducing S. Typhimurium contamination of the environment. Other than the packaging, the vaccine itself is identical.
The main changes announced today are:
In the future, the revalidation interval, which currently ranges from two to five years depending on the course, will be standardised at 4 years.
Currently, there is a two-month window in which Official Veterinarians (OV) can submit their final declarations, on completion of the course, if they want to set their next revalidation interval from the end of the window.
The revalidation window will be extended to a six-month period prior to the completion deadline date. If completed in this window, the date of the next revalidation would be taken from the deadline date and not the date of completion.
APHA is discussing ways of making invigilation more flexible, to help those working in sole-charge or remote practices. One option being investigated with course accreditation providers is remote invigilation, though this would come at extra cost.
All the multiple choice questions in the online exams are being reviewed to make sure they test the ability to perform the role, and in the future, candidates will be given more feedback at the end of the test (ie which questions they answered incorrectly).
In terms of CPD requirements, there will be clarification on what can be considered relevant CPD towards the 10 hours that need to be completed over the four-year timeframe.
Lastly, APHA has announced a raft of changes concerning course content, and that it will itself review all the courses to consider how the number of courses and topics can be rationalised, how to reduce the number of qualifications any OV might need and/or the time spent revalidating, and how to reduce the content without losing quality.
The BVA, which spearheaded the campaign for reform, has welcomed the announcement. Simon Doherty, BVA President, said: "We’re delighted that APHA has taken on board our members’ concerns with the current system and proposed improvements that should make the process much more fair and consistent while continuing to maintain high standards. This is a really crucial time for ensuring that the workforce retains skilled professionals and is at full strength to keep animal welfare standards high, protect public health and meet demand for export certification after Brexit.
"This piece of work is a shining example of what can be achieved when vets pull together to air concerns and make the case for change. We will continue to work closely with APHA to explore and put in place ways of making the revalidation process as fit for purpose as possible for this critical section of the workforce."

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.

The Society of Practising Veterinary Surgeons (SPVS) is putting out a last call to take part in the SPVS Salaries Survey 2015, open to everybody working in the veterinary profession.
The long-standing survey provides a benchmark for veterinary surgeons, nurses and support staff to see trends in pay and conditions. Designed to provide a complete picture of remuneration levels, the survey covers basic earnings, bonuses, dividends, overtime and benefits such as accommodation, car allowances, private medical insurance and pensions. It also includes questions on employment contracts, hours worked, out of hours and weekend working.
Peter Brown, SPVS Treasurer and author of the Salaries Survey said: “I have been compiling the survey results for a number of years but it never fails to enlighten me as to what is happening in the profession. I know it is also the go to reference guide when practices are recruiting to help ensure they are offering competitive salary packages.
“Participation in the survey is open to all and the more practices that take part, the more accurate and useful the information will be so we would urge everyone working in the veterinary profession to take a few minutes to complete the survey. It can be done online and the information is completely anonymous.”
To complete the survey online, visit www.spvs.org.uk or, for a printed version, telephone 01926 410545. The survey is open until 30 November 2015.
Poulvac CVI + HVT Marek’s vaccine provides the combination of the Rispens CVI strain and the HVT strain.
Zoetis says this combination of serotypes has long been recognised for providing strong, reliable protection against the disease, effective even against the very virulent pathotype of the virus.
John Kenyon, Zoetis National Veterinary Manager for Poultry said: "Marek’s disease remains a major problem for the poultry industry.
"To increase protection, it is a good idea to combine the CVI and HVT vaccine strains, and the new supplies of our vaccine help to make this more feasible.
“Currently in some longer-lived broilers and backyard laying hens a vaccine composed of just a single serotype is used, but it is advantageous to use a combination of serotypes to boost immunity further.”
Marek’s vaccination with Poulvac CVI + HVT can be performed in the hatchery at day of age via subcutaneous or intramuscular injection.
The Zoetis vaccine is supported with a range of services, including hatchery and vaccine audits, vaccine training and technical assistance.
The Royal College of Veterinary Surgeons is stressing the need for employers to check the registration status of the veterinary surgeons and veterinary nurses they recruit.
This comes following several incidences where veterinary surgeons have been found to be either not registered or registered in the wrong category. For example, foreign nationals wishing to work in the UK must be registered as home-practising members, not overseas-practising members. The latter category is for those practising overseas who wish to retain their MRCVS status.
Furthermore, there have been some cases of veterinary surgeons registering as ‘non-practising' and going on to carry out veterinary nursing roles, in the absence of relevant qualifications or being listed/registered as a veterinary nurse. This may be happening in cases where overseas veterinary surgeons are struggling to find work in the UK, possibly due to language difficulties.
RCVS President Jill Nute said: "Vets and veterinary nurses have complementary roles within the practice team. If someone wishes to undertake a veterinary nursing role, they should be qualified and registered as such. Many skills are taught in the veterinary nursing training that are not included in the veterinary degree. Although some veterinary nursing tasks can be carried out by veterinary surgeons, they certainly must not be undertaken by those who are not on the RCVS Register of Veterinary Surgeons".
She added: "Ours is a self-regulated profession and it is important that employers play their part by ensuring that practice employees are appropriately qualified and registered".
The registration status of vets and veterinary nurses can be checked on RCVSonline at: www.rcvs.org.uk/checkregister or www.rcvs.org.uk/vnlist respectively.
Virbac Animal Health has developed a 'Yield Wheel' to show vets the additional income that farmers can achieve through taking a tailored and more flexible approach to the management of their dairy herd through the dry period.
The company says this approach is made easier using its Cephaguard DC dry cow therapy.
While a 60 day drying off period is required for some cows, others may not need to be withdrawn from milk production for the full period, including those with a high body condition score in late lactation, high yielders and older healthy cows with an increased tendency for weight gain. For cows in these categories, a shorter drying off period can mean additional days of milk production and extra income for the farmer with no negative impact on future lactations or the cow's overall health.
The Yield Wheel shows how production and income can be maximised on a sliding scale from a standard 60 day drying off period down to 36 days, the shortest drying off period. It also shows the benefits which can be gained in terms of reduced discarded milk days in the case of cows with an unclear calving date.
Cephaguard DC dry cow therapy is the most recent entrant to the dry cow therapy market. With its 35+1 day withdrawal period in milk, Virbac says it offers farmers increased flexibility for the management of dry periods.
Brigitte Goasduf, Ruminants Product Manager at Virbac said: "For dairy farmers, it's all about milk. They're looking to optimise production and reduce waste while also ensuring that they treat infections effectively at drying off and prevent new infections which may reduce yield during the next lactation.
We've produced the Yield Wheel to highlight the tangible benefits of taking a customised and more flexible approach to drying off using Cephaguard DC. The data is provided in a practical and straightforward way and demonstrates the potential yield benefits that can be achieved from an overall herd management and income perspective. We hope it will prove a useful tool."
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.
VetsSouth, the new CPD congress and commercial exhibition being held in Exeter on 11th and 12th February, has announced that it will lead with a discussion about what practices can do to reduce bovine TB in clients' herds in 2015.
The congress, which is open to practising vets throughout the UK but aimed specifically at those in the west and south of the UK, will have three-and-half hours of discussion led by Roger Blowey (pictured right) and Richard Gard, with contributions from a number of practices in Gloucestershire, Devon, Somerset and Cornwall.
During a day on "cattle" on the Wednesday, Roger Blowey will also lead two sessions on "Recent dramatic changes in our understanding of cattle lameness", covering anatomy and foot lesions in the first and moving on to digital dermatitis and other infectious lesions in the second.
The rest of the programme is concerned mainly with small animals, the line-up of speakers including Dr David Williams on ophthalmology, Matthew Oxford on dentistry, Dr Andy Sparkes on feline medicine and surgery, Sarah Health on canine and feline behaviour and Anthony Chadwick on dermatology; plus six speakers from the Bristol veterinary school: Dr Jo Murrell and Gwen Covey-Crump on pain management, Dr Domingo Casamian Sorrosal and Dr Sonia Fonfara on cardiology, and Guillaume Chanoit and Ivan Doran on soft tissue surgery.
In addition, Professor John and Mrs Margaret Cooper will lead a day-long seminar on veterinary forensic medicine; the VDS will be running half-hour one-on-one sessions on improving consultation techniques; and there will be workshops on "ocular examination and pathology", "cat-friendly clinics" and "practical tooth extraction".
Exhibitors include Langford Veterinary Services, Vets4Pets/Companion Care, Protexin, Summit Veterinary Pharmaceuticals, Dechra Veterinary Products, Royal Canin, Bayer Animal Health, Natures Menu, Pet Medic Recruitment/Mi Vet, Teignview Veterinary Group, Henry Schein Animal Health, Axiom Veterinary Laboratories, iM3 Dental, Medimark Scientific, Merial Animal Health, Nova Laboratories, Improve International, DVH Veterinary Sales, Centaur Services, A.

TwistPak bottles have a hygienic interlock at the bottom, which allows them to be connected with a twist, creating one single mixing chamber which fits in all standard vaccination devices.
Currently, freshly mixing two vaccines requires a transfer needle.
Boehringer says the TwistPak bottle simplifies the mixing process while retaining the flexibility of using the products as a monovalent or combined vaccine.
TwistPak was jointly created with the industrial design and product development company DESIGNquadrat and awarded a Red Dot Design Award 2021 in the product design category.
Eva Joras, Global Brand Manager at Boehringer Ingelheim said: “TwistPak revolutionizes how vaccines are mixed.
"The mixing platform combines the best of both worlds: the unparalleled quality and efficacy of freshly mixed vaccines with the convenience of ready-to-use solutions.
TwistPak will be globally available in all registered presentation sizes starting May this year.
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.

The company says industry estimates are that 12 million accessible breeding ewes (91%) are not vaccinated against enzootic abortion in the UK, and that this should concern all practitioners with sheep clients.
Any flock with an abortion rate of over 2% could, it says, be suffering from the disease, and at a cost of £85 per aborted ewe, those are losses producers can ill-afford to ignore.
Stephenie Clarke from Ceva said: "Abortion remains one of the most significant reasons for loss in sheep flocks and an abortion storm can lead to crippling results on farm.
"Enzootic abortion caused by C. abortus remains the main cause of ovine abortion in the UK1 and once in a flock, takes time to control as exposed ewes can become latently infected."
Assure Ewe is a subsidised blood testing scheme open to all flocks with 50 or more breeding ewes. In contrast to other schemes, evidence of an abortion does not need to have taken place.
Blood samples should be collected from six ewes, with full farm and vet details also supplied. Upon results, Ceva says it will share information with the participating veterinary surgeon to discuss with the farmer.
Stephenie added: "Assure Ewe is a very user-friendly, simple scheme that will help facilitate conversations between vets and farmers while, at the same time, providing useful testing information to vets. Ceva encourages evidence based veterinary decisions, and this is just one example of such an initiative."
If C. abortus is identified in a flock, a veterinary-devised plan combining vaccination with Cevac Chlamydia, biosecurity and only purchasing stock from accredited flocks will assist disease control and eventual eradication.
For further information about the scheme, contact your Ceva territory manager.

The company provides official veterinarians, meat hygiene inspectors and other technical staff to the regulatory compliance sector, and its other clients include Defra, APHA, the Food Standards Agency, DAERA, AHDB, and several private organisations across the UK.
Hallmark says discussions have been ongoing with FSS since mid-2018, since when the company has faced increasing challenges in recruiting and retaining veterinary staff, as a result of eroding salary values and the weakening pound post-Brexit.
David Peace, Chairman of HallMark Meat Hygiene said: "The position we presented to FSS set out HallMark’s case for a substantial increase in funding to apply entirely to frontline veterinary salaries.
"Starting salaries for veterinary staff working with HallMark in this sector had altered very little during the past twenty years. As a responsible employer and trading partner, and with inflation and a weaker pound severely testing real pay levels, HallMark felt it necessary to address those issues robustly and directly to ensure staff are properly compensated and, as a result, that services are stabilised for the benefit of the Scottish meat industry."
"We’re naturally disappointed to part company with a valued customer such as FSS. By mutual agreement last year, we submitted a business case setting out what we believe is necessary to stabilise and maintain service delivery into the future. Ultimately, FSS decided not to accept that business case, and we consequently requested to be released from our contract with them.”
HallMark says it will continue to provide veterinary and technical services to government departments across the UK. Indeed, only last year HallMark’s parent company acquired MLCLS (Meat and Livestock Commercial Services Limited), the leading independent carcase classification business, originally owned by AHDB. HallMark is also an equal partner in its joint venture company, Probita Solutions Limited, which recruits and deploys vets in support of veterinary practices involved in TB testing activities.
The company also says it will continue to bid for major meat sector tenders in the future.
Mr Peace added: "This news should absolutely not be interpreted as a HallMark withdrawal from meat industry official controls. We will continue to offer the same diligence and dedication to welfare and hygiene standards, wherever opportunities arise, and it will be our mission to offer to government the most efficient and professional compliance services possible, optimising the cost of compliance delivery."
1,300 veterinary surgeons responded to the BVA survey, which was carried out in July. They were asked what Official Controls Qualification (OCQ) they hold or have held in the past, and give reasons for dropping a previously held qualification or choosing not to revalidate.
According to the BVA, many respondents criticised the current training and revalidation process, which is administered by Improve International on behalf of the Animal and Plant Health Agency (APHA).
Factors including time, the cumulative cost of renewing each module at regular intervals, a lack of relevance and duplication of learning across different modules were all cited as reasons for choosing to drop qualifications.
25% of vets who currently hold the Essential Skills OCQ say they are planning not to renew the qualification, with 67% saying it is because of the expiry of grandfather rights and 66% saying it is because they find the requirements too onerous.
18% of those who currently hold the Tuberculin Testing OCQ are not planning on renewing, either because they are finding the revalidation requirements too onerous (58%), too expensive (42%) or because the work is not sufficiently rewarding (42%).
35% of those who hold the Statutory Surveillance OCQ are not planning on renewing, primarily because of overly onerous revalidation requirements.
The largest drop off is predicted amongst holders of the Exports OCQ, 38.4% of whom said they plan not to revalidate.
Amongst the species bolt-ons, 45.5% of the holders of the Small Animal Exports OCQ, 51% of the Ungulate Exports OCQ, 66% of the Equine Exports OCQ, 72.5% of the Avian Exports OCQ, 47% of the Product Exports OCQ, 68% of the Germinal Products Exports OCQ and 32% of the Companion Animals OCQ said they plan not to renew, either because of the expiry of grandfather rights, or the expense or, in the case of Ungulate Exports, because revalidation is too onerous.
In the current system equine exports are included in the ungulate export OCQ, which the BVA says was a concern for those vets who only work with farm animals. APHA and Improve International have helpfully introduced an equine-only OCQ for exports that better meets the needs of equine-only vets.
BVA reports that it has had a positive meeting with APHA to discuss the survey results and explore practical solutions to iron out issues with the current system and make it easier to use. As a next step, BVA has agreed to review the modules and make recommendations for improving the structure of training and the revalidation process.
BVA President John Fishwick said: "The unprecedented response rate to this survey really hits home the strength of feeling on this issue. There is an urgent need to review and improve the revalidation process to safeguard against capacity and capability issues in this critical section of the workforce.
"It’s really positive that APHA recognises that there are issues with the current system and is keen to work with us to make it more proportionate and fit for purpose while continuing to maintain high standards. It’s more important than ever to retain skilled professionals so that the workforce is at full strength to respond robustly to disease outbreaks and meet demand for export certification after Brexit."
Andrew Soldan, APHA Veterinary Director said: "The integrity of our official controls and export certification is vitally important. The Official Controls Qualifications are a key part of this as they provide standardised OV training as well as assurance of high standards. I’m grateful to BVA for their assistance as we look to make further improvements to the system in the future."
Virbac has been granted a Limited Marketing Authorisation in the UK for its Gudair vaccine, indicated for the active immunisation of sheep and goats against Mycobacterium avium subspecies paratuberculosis (MAP).
MAP is the causal organism for Johne's Disease, a chronic infection of the intestinal system for which there is no cure.
According to Virbac, Johne's Disease enters most flocks following the introduction of infected stock, often breeding rams, bought at markets without checks on disease provenance. It is then spread by the faeces of often apparently healthy animals but which can contain huge numbers of MAP. The main clinical sign is a thin ewe resulting in poor productivity followed by inevitable death. It can be passed between sheep and cattle.
Ovine Johne's Disease (OJD) in sheep is widespread in Australia where annual death rates of up to 17% have been seen in infected flocks. Virbac says that trials conducted there have demonstrated that vaccination with Gudair can reduce the number of deaths due to OJD by 90% and reduce the numbers of OJD-causing organisms excreted in sheep faeces by 90%.
Ken Sibley MRCVS, Technical Advisor at Virbac says that the number of infected flocks in the UK is unknown and the disease often remains undiagnosed: "Johne's Disease can be a significant cause of loss in infected sheep flocks because of reduced productivity and high culling rates. Vaccination provides the only possible assurance when sourcing sheep from potentially infected flocks and will help to reduce losses from the disease should a farmer inadvertently introduce sheep into an infected flock.
"Lambs identified as replacements should generally be vaccinated between 4 and 16 weeks of age, subcutaneously behind the ear. Sheep over 16 weeks of age can also be vaccinated as this will reduce shedding of organisms in infected animals while bought-in replacements can be vaccinated on arrival at the farm. Sheep require only one vaccination for their lifetime.
"Following its success in Australia, we are delighted to be able to offer Gudair to veterinary surgeons in the UK."

Elanco Animal Health is reminding vets about the importance of correctly interpreting oocyst counts in the diagnosis of coccidiosis during the post lambing period.
The company says scouring lambs that are failing to thrive should immediately ring the alarm bells for coccidiosis. Typically, oocyst counts of >20,000 per gram are cited as diagnostic for coccidiosis in sheep, but counts of up to 100,000 oocysts per gram have been reported in apparently healthy lambs and disease can also occur in the presence of low or negligible counts where there is gut damage but before oocysts have been shed.1 These discrepancies can lead to misdiagnosis and as such, oocyst counts should always be interpreted with care.
Oocysts of the fourteen Eimeria species described as specific to sheep are indistinguishable from each other by eye and only two species - E. ovinoidalis and E. crandallis, are actually pathogenic.1 For this reason, diagnosing coccidiosis based on clinical signs of diarrhoea and oocysts in their faeces alone can generate false positives. This could lead to important differentials, such as Nematodirus battus infection (for lambs at pasture) being left untreated.
According to the company, false negatives are also a concern, particularly as prompt treatment of clinical cases with an anti-coccidial, such as diclazuril (Vexocan® 2.5mg/ml oral suspension) has been proven to reduce the convalescence period.2 Shedding of oocysts varies with disease progression and faecal counts can fluctuate significantly.3 For example, a delay between the development of clinical signs and oocysts appearing in faeces is common. Another possibility is sub-clinical disease, with affected lambs showing no typical outward signs. The gut damage caused by the parasite can be significant in these animals though, adversely affecting growth rates.
Elanco says that for reliable diagnosis of coccidiosis, faecal oocyst counts should be considered alongside disease and farm history, followed with Eimeria species identification if possible. The disease typically affects groups of lambs aged between 3-8 weeks old and is often triggered by a stressor such as castration, weaning, turnout and/or bad weather. If clinical signs appear around three weeks after such an event, the suspicion of coccidiosis can be heightened. For some farms, predictable stressors cause disease outbreaks year after year and in these cases, a metaphylactic dose of Vecoxan® can be administered to susceptible lambs 14 days after the trigger event.
Finally, the company says veterinary surgeons should also not forget the importance of good management when advising farmers about coccidiosis control. Lambing pen and high traffic area hygiene and age batching lambs are essential for long term control.

The academy will consist of three modules which will be launched in 2021. Those who complete all three modules will receive certification from Bimeda, and some exclusive branded goodies.
The first module is titled Bimeda Trace Elements in Dairy Cow Fertility & Pregnancy and is available now on Bimeda’s e-learning portal: https://bimeda-learning.co.uk. This module also accounts for 1 hour 15 minutes of CPD and vets can download a certificate when they complete the module. The module has also been accredited with 9 AMTRA points.
In the coming months Bimeda says it'll add a second module focused on the role of trace element nutrition in lamb and calf growth, and a final module focused on the role of trace elements in sheep fertility and pregnancy.
Bimeda UK General Manager Mark Cokayne said: "Trace elements play a critical role in the health and fertility of ruminants, yet historically this area has been somewhat overlooked in formal animal health education.
"Our customers tell us that they would like a deeper understanding of areas such as trace element deficiencies, toxicities and interactions, and the impact of these on ruminant health and fertility. We are pleased to respond to this market demand with our new academy, which will provide veterinarians and SQPs with additional knowledge to help inform their conversations with farmers."

Revozyn RTU, which contains 400 mg/ml Penethamate hydriodide, is the first ready-to-use injectable narrow spectrum Penethamate on the UK market. It can also be used to treat relapses of old infections.
Dechra says that the intramuscular injection works by diffusing through the blood vessels and accumulating in the udder tissue and milk, treating the whole udder effectively. Apparently the new formulation also features an ion trapping mechanism that results in high Benzylpenicillin concentration in milk and udder tissue.
Revozyn RTU comes in a 50ml multi dose vial. It has a 28-day shelf life after first use and has withdrawal periods of four days for milk and 10 days for meat and offal.
Dechra Brand Manager Emma Jennings said: "The treatment and control of mastitis is one of the largest costs to any dairy farmer. It affects productivity and cow welfare and we are delighted to be able to introduce this revolutionary product.
"Revozyn RTU can change the way that clinical and subclinical mastitis in dairy cattle is treated. Its narrow spectrum of activity means that the risk of antibiotic resistance is reduced and there is no need for additional animal handling, thereby saving time and protecting user safety.
“The flexible dosing of Revozyn RTU and 28-day shelf life also make it a cost effective option for farmers".

Defra has published a final epidemiology report into the Avian Influenza outbreak confirmed in Oxfordshire on 4 June.
The report concludes that at the time of writing (2 July) infection was confined to a single premise, and there is no evidence of infection on any contact or geographically close premises, or evidence of spread of infection to any other premises to date
While it has not been possible to conclusively identify the source of the infection, the two most likely sources of the outbreak are thought to be:
Deputy Chief Veterinary Officer, Alick Simmons, said ''This incident has demonstrated again the potential for avian influenza to be introduced into domestic poultry in the UK. The risk of further incidents, while low, remains. I urge poultry keepers to maintain the highest standards of biosecurity and to report suspicion of disease promptly including where records indicate increased mortality or reduced performance.''
Newmarket-based Test and Treat was one of three finalists, for its U-Treat test which enables vets to diagnose a UTI and get antibiotic sensitivity results in an hour.
Rachel Kirkby MRCVS, Business Development Director at Test and Treat, said: "It’s a great accolade to be recognised by such a prestigious award. The Vet Record Innovation Award celebrates new innovations that can bring about improvement and make a real difference to vets in practice – and that’s exactly what we’re aiming to do with U-Treat.”
The second finalist was the Animal Welfare Assessment Grid, developed by Public Health England (PHE), in collaboration with the University of Surrey School of Veterinary Medicine. Initially developed in zoos, rescue and research centres, there are plans now to develop it for use in small animal practice and in the farm sector.
The overall winner was PBD Biotech for Actiphage, its test for bTB and Johne's disease which gives very early detection, thereby allowing vets and farmers to prevent the spread of infection.

Elanco says Baycox Iron offers a time-saving flexible dosing treatment which complements the company’s existing piglet gut health portfolio.
Louise Radford, marketing manager at Elanco, said: "By treating piglets at two or three days old, it’s possible to allow enough exposure to the coccidiosis parasite to enable them to develop natural immunity, while preventing any damage to the gut caused by subclinical and clinical coccidiosis which leads to poor growth and low weaning weights.
"By combining treatments, it's possible to limit the number of times they are handled, which in turn reduces stress and enhances growth”.
Elanco also makes the Coliprotec vaccine against post weaning diarrhoea (PWD).
Louise added: “As farmers and vets prepare for the removal of zinc oxide as a treatment option next year, focusing on gut health throughout all stages of development has never been more crucial.
