CEVA Animal Health has now introduced Colibird, the UK's first colistin-based soluble antimicrobial approved for poultry.
According to the company, colistin is an important active in the UK's antimicrobial armoury, with a potent bactericidal action against Gram-negative bacteria, including enterobacteria and more particularly E. coli. Colibird is only one of a handful of products approved for layers that has a zero egg withhold. It also has almost zero levels of resistance, even with bugs variously resistant to other antimicrobials and is easily and efficiently administered in drinking water via header tanks or dosing pumps.
For further information please contact the large animal sales team or CEVA Animal Health Ltd, 90 The Broadway, Chesham, Bucks, HP5 1EG.
CEVA Animal Health has published an information booklet on Q Fever to help broaden awareness and understanding of the disease.
Q Fever is an emerging, worldwide disease that affects goats, cattle and sheep as well as humans. It is caused by the bacterium Coxiella burnetii and can induce late abortions, metritis, fertility problems, mastitis and low vitality in neonates born from carrier animals.
The new booklet explains how the disease is transmitted, the symptoms, diagnosis and how it can be managed and prevented. CEVA already have expertise in the treatment of diseases caused by Coxiella burnetii and have developed a vaccine that has been used under temporary license to control outbreaks in France and the Netherlands.
To obtain a copy of the booklet please contact CEVA Animal Health Ltd, 90 The Broadway, Chesham, Bucks, HP5 1EG. The proceedings from CEVA's recent symposium on Q fever, held in Marseilles in December 2009 are also available on request.
Agrimin has announced the launch of a new range of boluses for sheep and cattle that use 'eroding technology' to deliver a sustained supply of three trace elements for up to 180 days:
According to Agrimin, each bolus is designed to provide the full daily requirement of cobalt and selenium and the largest available daily supply of iodine to both cattle and sheep. The boluses do not contain any copper, an element known to cause issues in certain parts of the country, in closely managed dairy cows or in continental sheep breeds.
Each bolus is made up of two parts, held together by a soluble wrapper. After administration, the wrapper dissolves and the two halves remain in the reticulum where they erode and dissolve. This process delivers a continuous and regular supply of nutrients to the animal.
Agrimin's Dr Jamie Bennison said that the new range has been extensively trialled in New Zealand and at Glasgow Veterinary School: "Trials have confirmed a sustained release profile which ensures that iodine, selenium and cobalt levels are maintained throughout the active life of the bolus. In farm trials this has translated into higher levels of the elements in blood samples and improved animal productivity."
Treatment is one bolus per animal (48g for sheep; 160g for cattle) administered with an Agrimin bolus gun. One bolus is sufficient to meet the animal's full daily requirement for 180 days.
For more information about the 24•7 Iodine•Selenium•Cobalt range of cattle and sheep boluses, please visit http://www.agrimin.com/ or call 01652 688046.
The EU Commission has approved the marketing authorisation variation of Boehringer Ingelheim's PCV2 vaccine Ingelvac CircoFLEX. This approval allows the combined use of the pig vaccines Ingelvac CircoFLEX and Ingelvac MycoFLEX in the European Union.
Boehringer says it will market this unique vaccine concept under the name FLEXcombo. The company highlights that protection against two of the most prominent and costly pig diseases, Porcine Circovirus Disease (PCVD) and Enzootic Pneumonia, can now be achieved with a single injection instead of up to four injections. More than 70% of European pigs are currently vaccinated against both these diseases.
According to the company, the combined use of Ingelvac CircoFLEX and Ingelvac MycoFLEX is already registered and widely used in North America and Asia. It is globally the first and only product combination of its kind.
Dr. Joachim Hasenmaier, global head of Animal Health within BI said: "We are very proud that we can now also supply EU veterinarians and farmers with this latest innovation that will help tremendously in reducing the number of injections to pigs, supporting the wellbeing of the animals and the farm economics by saving a substantial amount of labour."
Animalcare has launched a new broad spectrum fluoroquinolone antimicrobial (Enrofloxacin) which the company says is highly effective in the treatment of a wide range of conditions and easy to inject, with excellent tissue penetration.
Enrocare solution for injection is presented in three strengths: A 25mg/ml (2.5%) injection for dogs, cats and exotic animals including reptiles, small mammals and avian species. The 50mg/ml (5%) injection is licensed for use in cattle, pigs, dogs and cats, whilst the 100mg/ml (10%) injection is licensed for cattle and pigs. In the case of dogs and cats a single daily dose is needed.
Animalcare says it has priced Enrocare competitively. In addition, the range has been launched with three offers: "Buy one get one free on the 50 and 100mg/ml" and "Buy two get one free offer" on the 25mg/ml pack size. These offers will last for four months until the end of September.
In cattle, Enrocare 50mg/ml, given by the subcutaneous route, is licensed for respiratory disease of bacterial or mycoplasmal origin and the 100mg/ml strength is licenced for both respiratory disease and E.coli mastitis (the latter given by slow intravenous injection). According to Animalcare, its low dose volume makes it particularly suitable for the treatment of respiratory disease in calves. In pigs >25kg Enrocare is licensed for the treatment of the respiratory and alimentary tract diseases of bacterial or mycoplasmal origin and multi-factorial diseases such as atrophic rhinitis and enzootic pneumonia.
Tony Liepman, Animalcare Market Manager said: "The recent successful launch of Cephacare flavour raised Animalcare's profile as a supplier of more up-to-date antibiotics and this is our latest addition which offers excellent efficacy at an attractive price."
Merial Animal Health has been found in breach of the NOAH Code of Practice for literature promoting the wormer Ivomec Super.
In the literature, Merial stated that Closantel injection (Janssen Animal Health) was effective against flukes aged 9 weeks or older, when in fact, at the time the undated brochure was distributed, Closantel was effective against flukes aged 7 weeks or older.
Merial did not dispute the facts alleged: the company had relied on an out-of-date detailer. The NOAH Code of Practice Committee emphasised the need for members to ensure, when giving comparative data in promotions, that up-to-date data is used. The SPC of any authorised product can be viewed on the VMD's website.
The Committee did commend Merial Animal Health for taking corrective action within two days of notification by the Complainant.
NOAH encourages those interested in finding out more to read the full details of the Committee's rulings on the NOAH website at www.noah.co.uk/code.
Intervet/Schering-Plough Animal Health has released diagnostic data which the company says indicates that calf scour problems caused by cryptosporidia are on the increase.
A summary of 2010 results from the company's ScourCheck scheme, which identifies infectious scour pathogens in calf faeces, show the protozoan parasite Cryptosporidium parvum being present in 37% of samples.
Intervet/Schering-Plough ruminant veterinary adviser Drew McGurren said: "Ever since we started testing calf faecal samples in the 1990s, rotavirus and cryptosporidia have always been identified as the two main pathogens implicated in infectious scour problems. But the latest data - and feedback from vets in practice - suggest cryptosporidia incidence is on an upward trend.
"Ten years ago our top line reporting used to refer to rotavirus being implicated in around a third of all infectious calf scour problems and cryptosporidia in roughly a quarter. But in 2009, we detected cryptosporidia in 30% of samples. And this year - from the 250 plus faecal samples we have looked at so far - the incidence seems to be even higher."
Drew stressed that scours caused by cryptosporidia are not always confined to housed calves: "Suckler calves between one and two weeks of age can be very susceptible to infection at grass, particularly if conditions underfoot are muddy around ring feeders. Early May has seen quite a lot of rain, and the parasite thrives in damp conditions."
The major source of cryptosporidia is thought to be either adult cows (which act as carriers without showing signs of disease) or infected scouring calves passing the parasite in their faeces. Drew said: "The infectious dose of the organism is very low and if ring feeders are not moved regularly the disease threat that builds up can be very similar to the housed situation. Faecal contamination of feed and water troughs can also be reduced by raising and covering them.
"Cryptosporidiosis in calves is often seen in combination with other diseases, particularly rotavirus. So vaccinating cows against rotavirus with Rotavec-Corona one to three months pre-calving - as well as a sound colostrum feeding regime and maintaining high hygiene standards - can often tip the balance in your favour."
Intervet Schering-Plough says that if cryptosporidia is diagnosed as the problem, parasite replication and excretion can be reduced with Halocur. This is the only product licensed to treat and prevent cryptosporidiosis. Administered orally to calves after feeding (daily for seven days), it can reduce the severity of diarrhoea and prevent the infection spreading to other calves. Treated calves have also been shown to require fewer antibiotic and anti-inflammatory treatments, as well as less rehydration therapy.
Vetoquinol has announced the introduction of Melovem to the UK market. Melovem is a new injectable preparation containing 5mg/ml meloxicam which is licensed for use in pigs and young cattle.
According to the company, meloxicam is the most widely used veterinary non steroidal anti-inflammatory injection in the UK. Presented in 100ml bottles, with a lower dose formulation, Melovem can be a cost-effective NSAID solution to leave on-farm.
Mark Leddy from Vetoquinol said: "We are pleased to be the distributors of Melovem in the UK. Melovem provides vets and farmers with a new, cost-effective meloxicam injection that is suitable for on-farm use."
Contact your Vetoquinol representative for more information on Melovem, or call Vetoquinol on 0800 1608197.
Vetoquinol is offering vets the opportunity to win one of five Selekt Cattle Pumps worth £240. In order to take part, you'll need to tell Vetoquinol about your experiences with Marbocyl 10% when treating acute mastitis.
Susan Mitchell, Vetoquinol's Large Animal Product Manager said: "This case study competition aims to gather information on the incidence and treatment of acute mastitis. Acute mastitis is a genuine veterinary emergency and rapid treatment is vitally important."
Vetoquinol says Marbocyl 10% has proven to be an effective treatment for acute E.coli mastitis, with a bactericidal action which does not liberate endotoxins. Administered intravenously, Marboyl 10% provides rapid improvement and an early return to milk production.
The company also says farmers have found toxaemic mastitis cases have benefited from the use of fluid therapy, using the Selekt Cattle Pump. Oral fluid therapy is a quick, easy and inexpensive option to intravenous treatment and improves the efficacy of hypertonic saline.
To enter the competition, visit http://www.vetoquinol.co.uk/, click the Marbocyl link on the right, and download and complete a brief case history.
Five winners will be chosen at random on 30th June 2010.
Intervet/Schering-Plough Animal Health has launched a new oxytetracycline spray which the company says offers more accurate antibiotic delivery whether the can is used in an upright or inverted position.
Alasdair King MRCVS, Intervet/Schering-Plough Animal Health veterinary manager, says new Engemycin Spray has been developed specifically to address problems reported with traditional aerosol cans:
"Antibiotic sprays are used widely, yet they can become a practical nuisance to both vets and farmers simply because many cans do not perform satisfactorily. All too frequently the nozzle leaks or detaches, the spray pattern is irregular - particularly if the can is held upside down as it so often needs to be - or the valve clogs before the can is empty. This can be a source of great frustration to users, but new Engemycin Spray overcomes all these problems."
Intervet/Schering Plough says Engemycin Spray combines a unique, quick-drying formulation with an innovative, non-clogging spray valve. The quick-drying formulation minimises wastage from the sprayed area, while the new valve - which works as well when the can is upside down - cuts spraying time and ensures more reliable and constant delivery of antibiotic. The valve is unique and designed to enable the can to fully empty.
Engemycin Spray is licensed for the treatment of foot and wound infections in cattle, sheep or pigs following surgery or physical injury. The new product is available now from wholesalers.
CEVA Animal Health is supplying a free, multi-dose injector gun with a self-sterilising needle system, with the purchase of bulk quantities of its luteolytic and uterotonic prostaglandin Enzaprost, while stocks last.
According to the company, the use of naturally occurring prostaglandins such as Enzaprost play an important role in any fertility management programme, working by causing lysis of the corpus luteum. Enzaprost can be used to control the timing of oestrus and synchronisation for AI; for the treatment of sub-oestrus or silent heat; for the induction of abortion up to day 120; for the induction of parturition and as an aid in the treatment of chronic metritis or pyometra where there is a functional or persistent corpus luteum. Natural prostaglandins also have a uterotonic effect which may be useful in the treatment of 'dirty' cows.
CEVA says any multi-cow injection programme has its risks, and that experience has shown that one in 250,000 injections can result in clostridial infection. Invariably this occurs in sequential animals, with the causal agent found in the bottle as a result of inadvertent needle contamination. Multi-dose syringes reduce the number of needle punctures into a bottle and the Sterimatic caps clean the needle before and after each injection helping to minimise the risk of infection. One Sterimatic cap can be used for 72 hours or up to 100 injections. The covered needle also provides increased safety for the operator, resulting in fewer needle stick and scratch injuries.
To find out how you can receive a free multi-dose injector with the Sterimatic needle protector system, which includes five caps and one needle protector, please contact your local CEVA territory manager

Vetoquinol has introduced a new smaller pack size for Reprocine, to help prevent wastage. The new 6 x 10ml pack is now available from wholesalers.
Reprocine is licensed in the cow for uterine atony during the puerperal (post-parturient) period, placental retention as a consequence of uterine atony and initiation of milk ejection in a stress-induced agalactia or in conditions requiring udder emptying. In the sow, Reprocine is licensed for uterine atony during the puerperal period also, supportive therapy of mastitis-metritis-agalactia (MMA) syndrome, initiation of milk ejection and for shortening of parturition period. Reprocine is an intraveneous or intramuscular injection and has the added advantage of no milk or meat withdrawal.
Susan Mitchell, Vetoquinol's Large Animal Product Manager said: "The new pack size reduces wastage which provides an instant cost-effective advantage.
"Reprocine is rapidly distributed and slowly eliminated. Efficient parturition and milk ejection is essential for newborn welfare and ultimately provides an economic benefit. Reprocine can be utilised in many reproductive associated conditions."
Reprocine is also available in 50ml bottles.
Novartis Animal Health has launched Zolvix, billed as the first truly novel anthelmintic class for livestock to be launched in more than 25 years, together with a new drenching system designed to make drenching faster, easier and more accurate.
Zolvix contains a new active ingredient, monepantel, which kills all key sheep gastro-intestinal nematodes (roundworms), including those resistant to the existing treatments.
According to the company, the development of this new drench follows the persistent challenge from worms that have developed resistance to the three other classes of drench - white (benzimidazole or 1-BZ), yellow (levamisole or 2-LV) and clear (macrocyclic lactone or 3-ML) and combinations of these. Zolvix has a unique mode of action and so forms a fourth generation of anthelmintic, which will be known as the 4- AD, or orange drench class
Novartis Animal Health has prioritised the UK and Ireland as key launch countries for Zolvix to provide their sheep farmers with an answer to the pressing challenge of increasing anthelmintic resistance.
Lesley Stubbings, an Independent sheep consultant and Sustainable Control of Parasites in Sheep (SCOPS) panel member, said: "Resistance has become an ever increasing threat since the last new anthelmintic group was introduced to the UK market more than 25 years ago. Zolvix offers farmers a valuable opportunity to maintain good worm control and prolong the effective life of the existing products. Following the SCOPS guidelines to carefully integrate Zolvix into worm control strategies, before the other groups fail, will allow our sheep industry to reap the full benefits of this new novel group."
A study carried out by Novartis in conjunction with the Hopkirk Research Institute showed that Zolvix treated sheep gained 33.5%, or 2.8 kg deadweight, more than sheep treated with a drench to which they were resistant.
Novartis Animal Health Brand Manager Simon Harris said: "Parasite resistance is a growing problem that decreases the productivity of sheep of all ages. Many veterinarians and farmers are concerned about this, with an increasing number of farmers reporting resistance to the three groups of wormers that have been available up to now, so the introduction of Zolvix is very timely."
At the same time, the company has also launched an award-winning new drenching system designed to offer 'a superior drenching experience for both animal and operator'. The new Optiline Drencher and Optivix backpack system were developed in collaboration with drenching specialists Simcro Tech Ltd.
The Optiline Drencher has already won several design and engineering awards, including a bronze award in the 2009 NZ BEST design awards, a coveted International Forum (IF) 2010 product design award from Germany and the prestigious Bayer Innovators Award for design and engineering.
It was also a finalist in the New Zealand Agritech Innovation Awards reached the finals in three categories of the 2009 New Zealand Trade and Enterprise International Business Awards.
The Optiline drencher is coupled with a durable, light Optivix backpack that has been specially tailored to provide left or right-handed operators with the same wide range of adjustment. It also has two drench cradles - at chest and hip level - to ensure maximum comfort.
Mr Harris said: "This drencher is best appreciated during use. Contact your local Novartis Animal health representative to arrange a trial."

CEVA Animal Health has launched Marbokem, a Marbofloxacin-based antimicrobial for the treatment of respiratory disease in cattle which offers the advantages of a one-shot protocol and a shock-resistant vial.
Marbokem is used for the treatment of respiratory infections caused by sensitive strains of Pasteurella multocida, Mannheimia haemolytica and Histophilus somni. CEVA says Marbofloxacin's efficacy has been proven in terms of re-treatment rate, success, speed of action and MICs in comparison with many frequently used quinolones and macrolides. (1,2,3,4)
According to CEVA, Marbokem's one shot protocol means it's quick and economical to use, while its presentation in an ergonomic CLAS vial makes for light and shock-resistant handling, resulting in fewer breakages and reduced costs. The company says Marbokem is also very competitively priced.

Janssen Animal Health has released the results of a survey which suggests incorrect worming strategies on many pig units in the UK are costing the industry dearly.
Most state they do not worm weaners, growers or finishing pigs at all and, while most sows are wormed, only a third treat newly-arrived gilts and boars in quarantine.
Phil Macdonald, UK and Ireland pig business manager at Janssen said: "Worm infestations can harm growth rate and feed efficiency, they can reduce abattoir returns and increase the cost of medication".
According to the company, the survey responses point to confusion among some producers on what constitutes a strategic worming programme. Most, 68 per cent, state they have implemented strategic programmes, but fewer than two-thirds of these cover all pigs on a unit and even fewer correctly base their programmes on the pre-patent period of worms.
Phil said: "It's important that all pigs on a unit are covered by the programme, otherwise there is a higher potential for reinfection. To be effective, the anthelmintic treatment periods need to be based on the pre-patent period of worms, so that treatment interrupts their life cycle.
"It requires a strategic worming programme with a broad spectrum anthelmintic such as Flubenol and Solubenol 100mg/g, which is the first and only water-soluble benzimidazole in the market. These are effective against larvae and worm eggs of a number of worm species as well as the large roundworm, Ascaris suum. Migrating larvae of the large roundworm cause Milk Spot lesions in pig livers, which are damaging to animal welfare and unit economics."
The make-up of UK units in the survey was 58 per cent breeder/finisher, 39 per cent finisher, 3 per cent weaner/finisher. Most, 68 per cent, use dry pelleted feed, 16 per cent wet feed and 16 per cent have both feed systems.
There is wide variation in worming programmes among producers. Most breeders worm their sows - 17 per cent once a year, 56 per cent twice and 11 per cent three times. With boars, 28 per cent worm them once a year, 44 per cent twice and 11 per cent three times. But only one-third (34 per cent) of breeders worm newly-arrived gilts and boars in quarantine.
72 per cent of producers with breeding sows who responded do not worm weaners and 80 per cent do not worm growers. Of the total responses, including specialist finishers, 68 per cent do not worm finishing pigs.
Most producers, 81 per cent, stated that they are aware that livers with Milk Spot lesions have to be trimmed or totally condemned, adding significant annual costs for disposal.
68 per cent admit to Milk Spot lesion levels of 25 per cent in consignments of pigs. Another 10 per cent experience up to 75 per cent livers with Milk Spot damage, and 3 per cent have had every pig liver in a consignment trimmed or condemned because of lesions. The feedback to producers comes from the BPEX Pig Health Scheme, of which 88 per cent of producers are members.
Only 58 per cent of producers are aware that more traditional worming methods allow pigs continuously to reinfect each other and their environment. Traditional programmes do not take the worm's life cycle into account.
The detrimental effect of worm damage that causes most concern to producers is lost growth/poorer feed conversion (29 per cent). Others considered the most important to be:
Phil says research shows that losses in daily liveweight gain alone add up to £2.31 per slaughter pig where liver condemnations are 30 per cent. "The frightening fact is that the loss is for every slaughter pig, not just those with Milk Spot lesions.
"In a 300-sow herd producing 23 pigs per sow per year that's a loss of £15,939 a year. On a 1,000-sow unit that exceeds a horrendous £53,000 annually, and these figures take no account of other areas of loss mentioned."
An adult female worm can shed hundreds of thousands of eggs each day, which pigs pass out in their dung. Worm eggs can remain infective for up to 10 years. Other pigs ingest them and the reinfection process begins.
Phil said: "A strategic worming programme that treats all pigs on a unit simultaneously is the only effective way to almost completely eliminate the problem. The survey has shown there is considerable potential for a large proportion of producers to improve productivity and cut costs by focusing on this critical area of management."
Janssen Animal Health is advising vets to be on the look out for coccidiosis as the spring lambing season approaches: cases usually rise in March and peak in April and May.
According to the company, some reports also suggest that the incidence of coccidiosis in calves may apparently increase during the grazing months. However, vets are reporting that interpretation of laboratory tests used to confirm diagnosis, such as oocyst count, can be problematic due to the ubiquitous nature of the Eimeria parasite in the UK.
Young animals may be infected by oocysts shed by asymptomatic carriers or infected older cohort animals. Low levels of challenge can help young animals develop immunity but exposure to high oocyst numbers, particularly in combination with stress can lead to clinical and subclinical forms of the disease. Diagnosis can be problematic, particularly in subclinical cases of disease where failure to gain weight is the main presenting sign and in clinical cases the differential diagnoses include all causes of scour in young animals.
Janssen Animal Health has suggested a few indicators that may be useful in identifying cases of coccidiosis. The Vecoxan Coccidiosis Survey in 2008 and 2009 asked farmers about their experiences of coccidiosis and identified that bad weather was a major trigger particularly in lambs; while castration and weaning were also factors in calves. As the parasite life cycle is 21 days, vets should be alert to disease 2-3 weeks after a stressor event.
The company has also suggested a few guidelines to aid interpretation of laboratory results:
Janssen says Vecoxan (diclazuril) does not interfere with the development of immunity and kills all stages of the parasite in the host.
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 launched the Intestinal Health Center for Poultry website (www.ihc-poultry.com), a website to keep producers, veterinarians, nutritionists, academics and students informed about this aspect of poultry production.
The company says it has published a wealth of practical, science-driven information and ideas to help producers manage costly gut diseases more effectively through vaccination, nutrition, sanitation and prudent drug use.
Marcelo Lang, global marketing director for the company's Poultry Business Unit said: "The new website lets you find virtually anything you need, quickly and easily, on specific intestinal health topics and products".
The website also offers a library of past issues of the company's Intestinal Health magazine and its predecessor, CocciForum, as well as three newsletters - Broiler Health, Layer Health and Turkey Health. In addition, the website includes an interactive feature called "Gut Reactions," where visitors can answer a frequently updated questionnaire related to intestinal health, immediately view survey results and then access links with more information on that topic. There is also a product finder to help users find Intervet/Schering-Plough Animal Health intestinal health products available in their market.
Marcelo added: "The Intestinal Health Center for Poultry is another example of Intervet/Schering-Plough Animal Health's commitment to educating the industry about this increasingly important segment of poultry health. We look forward to getting feedback on the site so that we can make it even better."
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.
The British Veterinary Association has launched a guidance poster to encourage farm animal vets to use anthelmintics responsibly, following ongoing concern about the development of resistance to these medicines.
According to BVA, misuse of anthelmintics in grazing animals, leading to resistance, is an increasing problem, which has now become a serious threat to the health and welfare of animals.
In response to growing concerns the BVA's Medicines Group has produced a poster that will be distributed to BVA members inside the Veterinary Record (23 January 2010 issue) and will be available to download from the BVA website.
The poster, accompanied by additional online guidance, clearly outlines Do's and Don'ts in the use of anthelmintics and carries the strong message "Think Twice Before Prescribing Anthelmintics". The poster is intended for display in veterinary practices as a reminder to vets and their clients of the need for responsible use of these medicinal products.
The poster carries advice on encouraging farm health planning and worming strategies, targeting the drug used to the parasite, the importance of not underdosing, quarantining incoming animals, and investigating and reporting suspected cases of resistance to the Veterinary Medicines Directorate (VMD). It clearly tells vets not to treat unnecessarily and not to blanket treat.
Peter Jones, Chair of the BVA's Medicines Group, said: "Every use of anthelmintics increases the risk of resistance developing. Veterinary surgeons have a duty to ensure anthelmintic use is judicious and limited to circumstances when treatment can be effective, targeted and based on sound veterinary diagnosis.
"The BVA advises all vets to work with their farming clients to develop a farm health plan that encompasses an effective worming strategy and a full grazing management programme to reduce the need for treatment.
"Vets must also promote good worming practice to ensure dosage is based on accurate weight measurements. Underdosing is a major factor in the development of resistance."
Professor Bill Reilly, President of the BVA, added: "Action to minimise the development of resistance is urgent and essential and we hope this poster will serve as a constant reminder to vets to think twice before prescribing anthelmintics."
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."
Vets and farmers must do more to improve dairy cow welfare in the UK, according to the British Veterinary Association (BVA). The call comes after careful consideration of major reports and opinions on the welfare of dairy cattle by FAWC (Farm Animal Welfare Council) and EFSA (European Food Safety Authority).
In a new policy statement, released last week, the BVA outlined the need for veterinary surgeons to take an active role in educating farmers and promoting better welfare, as well as working with farming clients towards a 'Herd Welfare Plan' that can be followed alongside the 'Farm Health Plan'.
The BVA says it recognises that some improvements have been made in certain welfare areas, such as longevity, but that issues relating to lameness, mastitis, housing and infectious diseases, such as TB, continue to be of concern.
Veterinary surgeons are well placed to offer help and advice in order to educate farmers on welfare aspects and how they affect herd health, productivity and ultimately, profit.
The policy also addresses issues around breeding for certain traits, which should always be discussed with a vet through a breeding plan, and the challenges of housing dairy herds. The BVA believes much can be done to achieve high welfare standards through good housing.
Finally, the BVA supports retailers who reward farmers financially for improving welfare standards for dairy cows and their calves.
Professor Bill Reilly, President of the BVA, said: "Recent reports have highlighted a number of major concerns about the welfare of dairy cows and their calves, and the BVA feels strongly that vets can take a leading role in addressing these issues.
"Lameness, mastitis, inadequate housing and infectious disease can all lead to poor welfare. Not only is this unacceptable for the animals, but it can be bad for the farmer's business.
"By working together, vets and farmers can and should do more to improve dairy cow welfare through Herd Welfare Plans, breeding plans and improved housing conditions."
Keith Cutler, President of the British Cattle Veterinary Association (BCVA), added: "While the UK enjoys higher standards of dairy cow welfare than many other countries, there are still some issues that need to be tackled.
"Vets and farmers need to work together to address problems. In my experience most farmers are pleased to discuss issues with their vets and then work in conjunction to improve the health and welfare, and ultimately the productivity and profitability, of their herds."
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.

You probably know that just reading content on www.vetsurgeon.org can count towards the 10 hours of undocumented Continuing Professional Development you are allowed to undertake each year. What you may NOT know is that other activities on the site can now count towards the requirement for 35 hours (on average) of documented CPD, without restriction. Best of all, it's free!
This is largely due to the way in which the VetSurgeon community has taken off over the last six months, meaning that the increasingly lively forums now offer a valid way to share knowledge and learn from each other.
To count towards your CPD requirement, your activities on VetSurgeon must be part of a documented process of appraisal and development. In other words, you must keep a record of your activity and how it has contributed to your professional development.
By default, VetSurgeon.org keeps a record of your activity on the website, which provides an auditable trail. To view your activity, click My Account (main menu) > View My Profile > View all activity. If no activity is displayed, checked that you have activity logging enabled in the 'Display Options' under 'Edit My Profile.
Currently, there are three main VetSurgeon.org activities you can take part in which can count towards your annual CPD requirements:
Participating in forumsIf you post a question on VetSurgeon.org and receive a reply, you may count the time spent posting your question and reading the answer as CPD. You should keep a note of what you learned.If you post a reply to a question, and needed to research your answer, the time you spend researching and posting your answer also counts as CPD. So, if you are a specialist answering a question in your sleep, that doesn't count. But if the question made you think, and you need to check your facts, that does.To count towards your CPD allowance, your forum posts must concern a subject which can reasonably be argued to advance your knowledge and proficiency as a vet (so RCVS-bashing posts won't qualify!)
Publishing content on VetSurgeonVetSurgeon offers a number of additional opportunities to self-publish on the site, and any time spent researching and publishing qualifying content (which can reasonably be argued to advance your knowledge and proficiency as a vet) can count towards your documented CPD. For example, Practical Veterinary Tips (http://www.vetsurgeon.org/blogs/veterinary-tips/default.aspx) is a newsfeed in which members can publish clinical tips; the time you spend researching and publishing a tip would qualify.
Documented readingAdditionally, time spent reading the site where you document specifically what you have read and what you have learned can also count towards your documented CPD.
