A rural social scientist has argued in this week's Veterinary Record that the dwindling influence of vets in the public health arena threatens food safety in the UK.

Philip Lowe, from the Centre for Rural Economy at the University of Newcastle, argues that a shift in practice from treating animals used for food on farms to looking after pets in urban communities, is largely to blame.

The proportion of time vets in private practice spent treating animals used for food halved between 1998 and 2006. Most vets run their own businesses, and pet owners have proved a more sustainable and lucrative source of income than farmers.

Professor Lowe sympathises with the need to make money, but laments this drift towards the profession turning into "another private sector service industry."

He says this fails to make use of vets' considerable and wide ranging expertise, adding: "I would argue that it also diminishes the public standing of the whole profession. I certainly couldn't imagine the medical establishment in this country accepting a role that marginalised public health, even if the NHS did not exist. More seriously for all of us, I believe that not involving vets in this important area also puts food safety in the UK at risk.

"At the same time we live in an age when there is real and widespread public concern about welfare standards for farm animals, threats from animal diseases old and new (such as blue tongue, bird flu and swine flu), and food safety."

Professor Lowe says that in the past, the veterinary arm of government traditionally provided leadership for the profession that was embodied by the Chief Veterinary Officer and was underpinned by the proportion of vets' income derived from public funding. But this is no longer the case, and is further undermined by the percentage of vets employed by government having shrunk from 11% to 4% over the past 40 years.

Professor Lowe argues that the profession needs to rethink its role and the direction in which it is travelling. He says there needs to be more specialist support and training for student vets and novice practitioners so that they are not put off from farm practice before they have had a chance to develop their skills and confidence in this area. 

However, he cautions against returning to the stereotype popularised by the fictional James Herriot vet, who was depicted as a mainstay of the rural community: "The farm vet's position and respect for their expertise needs to be restored, but not in the old Herriot mould. He or she has to take on the much greater challenge of risk and welfare regulation and management across the whole food system".

Intervet/Schering-Plough Animal Health has announced that it has received marketing authorization from the European Commission for a single-shot vaccination schedule of its Porcilis PCV vaccine against porcine circovirus type 2 (PCV2) infections.

The new approval allows vaccination with 1 dose of 2 ml in pigs from an age of 3 weeks onwards (known as the 1 - 2 - 3 approach) in the case of low to medium levels of maternal antibodies against PCV2, and also to include reduction of mortality as an additional indication. This new single-shot application for Porcilis PCV offers additional flexibility over the currently available dosage scheme of this vaccine, which has been available in Europe since April 2009.

Intervet/Schering Plough says the major characteristics of Porcilis PCV are that: (1) it contains the Cap-2 subunit antigen coded by ORF2 and therefore induces strong immunity against PCV2 infection; (2) it is combined with XSolve, an adjuvant offering immunity until the end of the finishing period; and (3) is able to break through of all levels of maternally-derived antibodies in piglets depending on the vaccination schedule used.

The company adds that one single dose of Porcilis PCV has been demonstrated to induce both humoral and cell-mediated responses against PCV2, despite the presence of low to medium levels of maternal antibodies. According to a recent study published in Vaccine, the immunity induced by a single dose of the vaccine resulted in reductions of viremia, viral shedding and viral load in tissues in vaccinated pigs as compared to controls. Field trials have also demonstrated that vaccination of pigs at 3 weeks of age or older reduces the presence of virus load in the blood and reduces weight loss associated with PCV2 infection during the fattening period.

Infection with PCV2 is known to cause a variety of syndromes in pigs, together known as Porcine Circo Virus Disease (PCVD). Symptoms may include clinical signs such as weight loss or failure to grow, enlarged lymph nodes, difficulty in breathing, pale skin and jaundice.

Scientists from the Institute for Animal Health, Pirbright, UK Met Office and the Jersey State Veterinary Service and Jersey Meteorological Department, are working together on an early-warning system to help defend cattle against the spread of 'bluetongue' disease, according to a study published today in Weather.

The team is fusing meteorological data with ecological information to anticipate when disease carrying midges are likely to be carried on the wind from the continent to the UK and Channel Islands.

Lead author Dr Christopher J. Sanders from the Institute for Animal Health said: "The bluetongue virus, BTV, represents a major and unprecedented epidemic which has spread across Western Europe since 2006. While accurate estimates of costs incurred are not yet available, it is estimated that these could be in the order of many tens of millions of pounds."

BTV is carried by small biting midges, Culicoides, one of the smallest species of biting flies found on livestock. One bite from a midge fully infected with BTV can be enough to lead to infection in cattle and sheep, which can be fatal.

Since 1998 the range of the African species of biting midge has expanded from the Mediterranean basin resulting in an overlap with the range of European species. This enabled European species of midge to pick up virus from infected animals for the first time and go on to transmit it in Southern Europe. However, the arrival of BTV in northern Europe in 2006 was independent of this northwards movement of BTV, jumping north rather than from a gradual spread, and was reliant on transmission only by European midges common and widespread in the area.

In 2006 the disease was found in Belgium, France, the Netherlands, Luxembourg and Germany; 700 km north of previous European outbreaks. In June 2007 the disease was once again reported in Germany and by October 2008 24,000 cases were reported in France alone. In September 2007, the first cases of BTV were discovered in the UK, where fortunately the outbreak was small.

The danger that the disease may again spread to the UK from across the channel is of special concern to the Channel Island of Jersey, which maintains a world renowned cattle industry, but is at heightened risk of infection if the disease becomes established along the Cherbourg peninsula or the Normandy and Brittany coastline.

The risk comes from the possibility that the tiny midges can be carried on the wind from the French coast to the Island. To monitor this threat the team set up midge light traps in farms across the island to monitor midge activity and to identify the presence of any potential vector species.

The results were then collated and analysed alongside data from the Jersey Meteorological Department, which allowed the team to pinpoint when livestock were at risk from a number of locations on the mainland. This information was fed into the UK Met Office early-warning website which has also been used on the mainland to help predict and defend against the disease.

"Environmental conditions, especially temperature, wind speed and direction have a significant impact on the biting midge in terms of activity and abundance," concluded Sanders. "Monitoring the midge population in Jersey will provide the farming community on the mainland with knowledge of when the midge season commences in the diseased areas of the near continent."

A new injectable antibiotic with nil-milk-withhold licensed to treat foul-in-the-foot in a single shot has been launched by Pfizer Animal Health.

Naxcel Cattle's active ingredient is ceftiofur in a patented sustained-release formulation. According to the company, one injection provides a full course of antibiotic therapy, giving seven days of therapeutic blood levels against the majority of inter-digital necrobacillosis ('foul-in-the-foot') pathogens.

Pfizer vet Dave Gilbert says the expectation is that Naxcel Cattle will make on-farm therapy easier and help improve treatment compliance and thereby first treatment success rates, compared to treatments which require repeat injections. "Having the full course in a single injection simplifies treatment protocols and eliminates a number of reasons for non-completion of treatment, such as forgetting a second or third dose, or not giving them because of apparent symptomatic recovery from the condition."

The site of injection for Naxcel Cattle is the subcutaneous area at the base of the ear (see Figures 1 & 2). Injection instructions are supplied in the product pack. Dave Gilbert suggests that provided cattle are adequately restrained during administration the injection technique is simple and straightforward. The dose rate is 1ml/30kg body weight and up to 30ml can safely be given into each site.

Eskimo, a reindeer at Edinburgh Zoo has received life-saving surgery just in time for Christmas, making him the first reindeer in history to receive keyhole surgery.

Vet Romain Pizzi successfully removed one of Eskimo's testes, which had been lodged in its abdomen since birth, using specialist surgical instruments donated to the zoo by one of Ark Surgical's strategic partners Surgical Innovations.

The zoo was worried that the retained testicle may have been developing into a tumour giving off abnormal hormones, and that this could become life-threatening. Thankfully, zoo surgeons found that the retained testicle, although abnormally sized, had not yet developed a tumour.

It is thought that the abnormal testicle was affecting Eskimo's production and flow of testosterone and, as a result, he was showing submissive behaviour and being bullied by the other male reindeer in the herd. He had also started to show some abnormal and delayed antler growth and development. Removing the testicle will halt any abnormal hormone production so hopefully Eskimo will return to full vigour just in time for Christmas.

Gavin O'Brien, Director at Ark Surgical said: "We were only too happy to help when Romain mentioned the challenging operation faced by Eskimo and in the season of goodwill we approached Surgical Innovations who kindly donated the instruments for this pioneering surgery." 

Although laparoscopic surgery is routine in humans, the standard procedure in animals is still open abdominal surgery.  Open abdominal surgery is 20 years behind human medical advances and has a number of negative factors on animals such as more post-operative pain, slower recovery and a higher risk of post-operative complications and infections.

Romain, a veterinary surgeon for the Royal Zoological Society of Scotland, based at Edinburgh Zoo, said: "Laparoscopic surgery is still very uncommon in veterinary medicine, even amongst common species such as dogs, cats and horses, so for keyhole surgery to be carried out on a reindeer shows a great advancement in veterinary surgery."

It is estimated that nearly one out of every two households in the UK are pet owners. Veterinary surgeons perform on average 600,000 open abdominal procedures annually but it is believed that less than 1% of vets currently practice laparoscopic surgery. 

Romain believes that with the right instrumentation available through innovative companies such as Ark Surgical, UK vets now have more opportunity than ever to introduce laparoscopic techniques as part of their operating procedures.

Romain said: "This procedure was only really possible thanks to a cutting-edge designed retractor which we were able to use in this case. Ironically although a reindeer is a reasonably large animal, due to their unique anatomy and massive four chambered stomach that takes up most of the space in the abdomen, there is a very limited internal operating space. For this reason the operation was much more difficult than in a human, or in a dog, where there is more space to work, despite their smaller size."

"We were especially pleased with how quickly Eskimo recovered after surgery, he was standing and happily eating lichen again within 10 minutes of recovery from anaesthesia. He hardly seemed to notice he had even had surgery, although he was still slightly groggy from the anaesthesia. This would simply not have been possible with traditional open abdominal surgery, as the long wound would have been much more painful and debilitating."

The minimally invasive nature of laparoscopic surgery means there are numerous benefits for animals such as a reduction in post-operative pain, a faster recovery and reduced post-operative care.   It also has a decreased risk of infection after surgery and a lower risk of any wound complications. 

For veterinary surgeons laparoscopic surgery can offer better visualisation of the operated area, allowing them to be more precise and reach areas that are difficult to see in open surgery such as the liver and pelvic canal.

Romain carries out laparoscopic operations on dogs, cats and exotic pets at his own veterinary practice Inglis Veterinary Centre (Scotland) and has pioneered several new laparoscopic techniques.

He said: "Laparoscopic surgery has so many benefits for the animal, the veterinary surgeons and the zoo, so there is no reason why it should not be more common practice within veterinary surgery.  I hope Eskimo's experience helps raise its profile and encourage more veterinary surgeons to look in to it as a standard surgical procedure."

Ark Surgical offers a wide range of laparoscopy instruments and peripherals to vets across the UK and to suit all budgets. The company says it is already working with many of the UK's leading vets and agencies such as the Royal Zoological Society of Scotland, as well as the UK foremost laparoscopic medical device manufacturer Surgical Innovations, to be at the forefront of veterinary laparoscopic surgery

Thought to be the first agreement of its kind between a buying group and a veterinary practice, Norfolk Farm Vets and agricultural purchasing group Anglia Farmers Limited have come together to offer mutual members and clients a beneficial discount on their monthly vet account when invoiced through Anglia Farmers.   

Anglia Farmers livestock manager Simon Leach said: "With more than 650 livestock members, Anglia Farmers is keen to give a financial edge wherever possible. Veterinary costs are as much a part of the overall costs we already help with such as feed, equipment and fencing.  In terms of dairy, they account for around 0.8p a litre of milk, accumulating to an average of around £1,200 a month for a typical East Anglian dairy of 150 head.  Our discount agreement with Norfolk Farm Vets is a very positive step in aiding our members to save even more money through Anglia Farmers."

Both parties agree that the time and administration cost saving benefit is equally important.

Molly McKay of Norfolk Farm Vets, which has clients throughout the Eastern Counties as well as Lincolnshire, said:  "Anyone involved with livestock knows how time-consuming all the paperwork can be.  Each month Anglia Farmers collates all the supplier invoices, sends them on to members as part of their monthly statement with a single covering invoice which is so much easier than receiving them piecemeal. And it streamlines administration and cashflow for us as well."

CEVA Animal Health has extended its range of injectable anti-infectives with Florkem, a Florfenicol-based antimicrobial for the treatment of respiratory tract infections in cattle and pigs.

According to the company, Florfenicol shows a strong in vitro bactericidal activity against the most common respiratory tract pathogenic bacteria and can be used as a time or dose-dependent bactericidal depending on the target. It also offers very good diffusion in most tissues for an efficient response.

CEVA says Florkem^® is very convenient to use: a specifically developed formulation provides for better syringeability, in both warm and cool temperatures, making administration quicker and easier. It is presented in an ergonomic CLAS vial, which is shock resistant, light and easy to handle in the field.  This means fewer breakages, which can reduce costs while maintaining efficacy.

Britain's dairy industry is doomed unless it takes more effective steps to control the spread of endemic diseases like tuberculosis and bovine virus diarrhoea, according to a leading cattle vet.

At a conference on infectious disease at the Royal Veterinary College last week, Devon practitioner Dick Sibley warned that the management and economic trends in the UK dairy industry are increasing the risk of disease transmission - and its potential impact once it does enter a herd.

Figures he obtained from the British Cattle Movements Service show that about four million cattle, or half the total UK cattle herd, are moved from one premises to another each year. Those being sent for slaughter were unlikely to spread infections but moving cattle of unknown disease status to new premises greatly increased the risk of bringing in new diseases. "If you set out to design a system that guarantees that we will continue to have problems with endemic disease then I could not think of a better one than this," he said.

Cattle numbers are increasing in those areas like Devon and Cheshire which already have among the highest population densities for dairy animals in the world - and are also the main hot spots in the current bovine TB epidemic. Farmers feel compelled to buy in heifers from as far afield as Germany and Holland to replace animals culled as TB reactors, as they will lose bonus payments from customers who demand that they maintain constant levels of production.

Several other factors also increase the likely impact of disease in a previously healthy herd - the concentration of cattle numbers into fewer but larger units, the growing emphasis on cattle kept indoors all year round and breeding for high yielding animals that are more vulnerable to disease. Meanwhile, a shortage of skilled manpower means that half the available stockmen are shared between farms and can therefore be responsible for bringing in disease.

But farmers have little or no control over some of the more important risk factors - particularly movements of badgers and the presence of diseased herds on neighbouring premises. "So these farmers with big herds in high density areas and neighbours that have the disease are done for unless we can do something serious to manage the risks."

Dairy farmers can work with their veterinary advisers to reduce risk using the four main pillars of disease control - improved biosecurity, better surveillance, appropriate vaccination and containment of disease transmission within the herd. But diseases also had to be tackled on a national level and if DEFRA is unwilling to take on the task, he proposed the creation of an independent livestock disease agency with sufficient staff and resources to carry out its remit. The costs of running such a body should be shared among all those stakeholders with an interest in preserving an economically viable dairy industry, including, for example the cereal producers who provide the dairy industry with much of its food materials, he suggested.

Norbrook Laboratories has launched Closamectin, a parasiticide which the company says will revolutionise cattle farming and parasite control in meat producing animals.

Closamectin Pour-on is a solution which can quite literally be poured onto the back of animals. It simultaneously treats fluke, worms and external parasites. The new product is the culmination of a six year research project costing £3.5 million and involving 80 scientists at the company's headquarters in Newry Co Down.

Norbrook says it will bring immense benefits for farmers whose cattle are often ravaged by parasitic attack. Fluke in particular can have devastating effects both on beef and dairy herds, seriously weakening, and in some cases killing the animals by destroying their livers. At the very least it collectively costs farmers around £17 million per annum by reducing the weight of beef cattle and the milk yields of dairy cows.

Fluke used to be confined to the western parts of Britain, together with Scotland and Ireland, but global warming has seen other parts of the UK experiencing the same mild and wet conditions on which the parasite thrives. Consequently it is on the rise.

Currently fluke is treated by injection or oral drench - both time-consuming and difficult processes for the farmers which can also be stressful for the animals. In contrast pour-on solutions can be applied swiftly and easily with no detrimental impact on cattle.

Norbrook has been awarded licenses for Closamectin Pour-on in both the UK and Ireland. This is a very significant market: the countries have a combined cattle population of 17 million. There are also plans to roll out the product in other countries.

Developing a pour-on to deal with these parasites has baffled scientists for 20 years. Alistair Couper, Norbrook's Chief Vet said: "This is the Holy Grail of farm animal veterinary medicine. It was a highly complex challenge for our research team. They had to develop a product which would treat different conditions simultaneously and have a molecular structure which could be absorbed straight through the skin. This is a ground breaking achievement and a brilliant piece of science"

Lord Ballyedmond, Chairman of Norbrook Laboratories said: "This is a very important milestone for Norbrook and for livestock and farmers worldwide. We have invested heavily in research and development and the results are there for all to see. We are delighted to have beaten other multinationals.  We have now developed the world's most effective remedy for parasite control in cattle that our entering the food chain. I am pleased to state that our business has grown this year indigenously at 12% despite the recession, beating our competitors. This tremendous breakthrough is a great testimony to the brilliance of our scientists in Newry and also to our policy of investing in research. "

Lantra, the UK Sector Skills Council for environmental and land-based industries, has backed a report that addresses veterinary expertise in food animal production.

The 'Unlocking Potential' report, produced by Professor Philip Lowe on behalf of Defra, identifies the potential for veterinarians to increase their role by providing expert advice to the farming and food industries.

Industry Partnership Manager, Lisa Jarvis, said: "Lantra welcomes this report on the farm animal veterinary services, which encourages the discussion of the future of veterinary businesses and services, role of support staff and para-professionals. We are pleased to be recognised alongside Defra, the RCVS, the BVA and the NFU, as a key organisation to drive the development of training and career structures in the industry."

The report highlights that the scale of and demand for veterinary technical services for farm animals and the food sector should be investigated, identifying training needs and obstacles to skills development. This is currently being addressed through Lantra's LandSkills project which is part of the Rural Development Programme for England.

Lantra's National Director for England, Madge Moore, said:  "Through the LandSkills programme, Lantra has already engaged with a number of veterinary practices from across the North East, Yorkshire and Humber, East Midlands and West Midlands to deliver practical courses and farm health plans to eligible farming enterprises.  So far in Yorkshire and Humber vets have run a number of practical poultry courses where farmers have learnt how to carry out post-mortems on their own flock so they can find out if there is a recurring problem which they may need to rectify.  LandSkills West Midlands is also currently recruiting a number of vets in the region to deliver a farm health plan initiative."

Madge continued:  "Working with farmers and vets as part of LandSkills means that we are in a great position to look at the demand of these services whilst highlighting the importance of farmers utilising their vets more effectively by showing them what they can offer. However we also look forward to working with partners in leading the continued progression of the veterinary profession."

Forum Animal Health is launching a new programme designed for transition cows to help avoid milk fever relapses: the Milk Fever Pack.

According to the company, the new Milk Fever Pack provides a continuous and complete supply of readily available oral calcium to avoid relapses which also gives the cow extra support until her system is back in control. Unlike intravenous calcium, oral calcium will not suppress parathyroid hormone (PTH) release and therefore will not turn off the cow's natural mechanism to regulate blood calcium levels.

Each pack contains one sachet of Agger's^® Fresh Cow which supplies essential calcium, energy and rehydrates the cow; and two tubes of Botonic^® Calcium which create a mild metabolic acidosis to enable the cow to mobilise calcium efficiently.

Forum Animal Health says the new Milk Fever Pack has been developed in close collaboration with a leading veterinary nutritionist to allow veterinary surgeons to be involved at an earlier stage. The veterinary surgeon can then leave a follow-up protocol for the client to use, helping to avoid milk fever relapses. It gives veterinary surgeons a chance to introduce standard operating procedures into herd health plans bringing better control of milk fever on farms. 

For more information, please contact Forum Animal Health on 01737 781416 or animal.health@forumgroup.co.uk.
