The vaccine to control boar taint was developed in Australia and is produced by Zoetis. It has been available since 1998. Because of its history of proven performance, this vaccine has since been introduced in more than 60 countries and continues to be introduced around the world.
What the experts say
"It is an obligation for all of us to produce meat humanely. The concept of vaccination in place of castration to control boar taint must surely bring about improvements in animal welfare and must therefore be supported."
-Dr. John Mackinnon, pig veterinarian consultant18
Professor Dr. Rico Thun , Zurich University, Reproductive Medicine Clinic, sees major advantages in vaccination to control boar taint in comparison to early slaughter and physical castration with anesthesia."The vaccination is effective, reliable, practical as well as animal-friendly and currently the best alternative to prevent boar taint." 28
"Vaccination to control boar taint provides several potential public as well as agribusiness advantages over physical castration, including animal welfare improvements, potential cost savings in procedures, and gains from higher growth rates for pigs. Our findings suggest that vaccination is a socially viable alternative."
— Dr. Carl Johan Lagerkvist , et al.29
According to Professor Dr. Frank Dunshea, the most promising alternative to physical castration is vaccination to control boar taint, which uses the animal's immune system to inhibit normal functioning of its testicles. "Vaccination offers a great potential because it enables the growth of non-castrated males until the final stage of growth, all this without the risk of sex odor. Additional benefits are an improvement in feed intake and in growth, a reduction of animal fights and their sexual activity."
—Prof. Dr. Frank Dunshea, , University of Melbourne, Australia27
"Vaccination shows very good potential for preventing boar taint while capitalizing on the growth, feed efficiency and carcass leanness of boars up to the point of vaccination."
—Prof. Michael E. Dikeman , Department of Animal Science and Industry, Kansas State University31
"Decision makers in integrated companies will quickly see the benefits of improving feed conversion and re-gaining the efficiency of growth which they have been losing as a result of castrating piglets."
—Prof. Dr. John Deen , Veterinary Population Medicine, University of Minnesota
