UK pig producers seeking to manage Enzootic Pneumonia (EP) in their finishing herds now have access to a powerful new in-feed antibiotic option from Schering-Plough Animal Health.
Derived from further fermentation of tylosin and available as a premix for medicating pig feed, Aivlosin demonstrates a three-fold increase in bio-availability. The specific activity against M. hyopneumoniae has been enhanced several times over its parent molecule. In field trials in the UK and Ireland Aivlosin has proved highly successful in the treatment and prevention of E. P.
Speaking at the launch of Aivlosin in the UK, Schering-Plough Pig Advisor Ross Kelly BVMS, MRCVS explained: "Aivlosin is an entirely new macrolide and generates accelerated levels of antibacterial activity at the site of infection. This activity treats the disease directly within the respiratory system and also limits its establishment and progression. This means infected pigs recover more quickly, return to optimum growth rates faster and the burden of disease challenge is limited on the unit."
Schering-Plough is now hosting a number of briefings to provide pig vets with the background to Aivlosin. "The feedback we are getting is very positive," said Mr. Kelly. "E. P. remains a costly challenge for UK pig producers and vets feel the launch of Aivlosin offers a valuable new
treatment option."
Published data on clinical trials in Europe have also shown Aivlosin to be successful in treating diseases caused by other bacteria, including those that have poorer susceptibility to other antibiotics. "In finishers that have been treated with Aivlosin, lung scores showed a measurable improvement over traditional in-feed alternatives. We have data to show that Aivlosin is a cost-effective new treatment. The standard 1Kg per tonne inclusion rate and a 7 day duration of treatment offers both the vet and the producer a responsible, targeted and effective method for treating and preventing Enzootic Pneumonia." pointed out Mr Kelly.
Aivlosin is categorised as MFS and can only be included in pig feed subject to a Medicated Feedstuffs (MFS) Prescription written by the herd vet. Producers should discuss any intended medication programmes with their vet and feed company.
