Co-marketing for PRRSpig vaccine
THE first inactivated vaccine to fight reproductive performance problems caused by Porcine Respiratory and Reproductive Syndrome (PRRS) in breeding sows and gilts is being co-marketed in the UK by Merial and Boehringer Ingelheim.
The product is being marketed as Progressis by Merial and Ingelvac PRRS KV by Boehringer Ingelheim.
Brian Rice, Merials UK pig director, says trials show using the vaccine in infected herds increases the number of weaned piglets a sow a year, lowers the number of premature-born piglets and results in fewer cases of fever after farrowing. Vaccinating gilts also improves their adaptation when entering an infected herd, he adds.
An initial course of two doses, 3-4 weeks apart, is given to gilts three weeks before first service and to sows at anytime. An annual booster is needed for every pregnant animal between 60-70 days of pregnancy. *
