IMPROVAC® allows male pigs to maintain their natural male growth patterns up to the time of the second injection, resulting in a more efficient feed conversion and producing the same quality meat of physical castrate pigs. It also improves the welfare of pigs by avoiding the stress, pain, and mortality associated with the physical castration of piglets. Furthermore, physical castration changes the natural growth patterns of boars, so they convert feed less efficiently and produce fatter carcasses.

IMPROVAC® is administered as two doses: the first ‘primes’ the immune system and the second (at least 4 weeks later) stimulates the production of antibodies to control boar taint.

Pfizer Animal Health – the producer of the product plans to train and assist veterinarians and their pork producer clients on the proper use of IMPROVAC to help them maximize the value that it can deliver to their operations.
