On May 11, 2016, the BLM released new(?) statistics on the wild horse and burro population.
Marco Coutinho da Silva, DVM, MS, PhD, Diplomate ACT, associate professor-clinical of theriogenology and reproductive medicine in OSU’s Department of Veterinary Clinical Sciences, and Dr. John Lannutti, professor of Materials Science and Engineering in the College of Engineering, are collaborating in an effort to curb the overpopulation of wild horses and burros in the United States, thanks to an $800,000 grant from the U.S. Department of the Interior’s Bureau of Land Management (BLM).
Wild horses and burros (WH&B) can be found roaming free in many western states. The animals have been federally protected since 1971 as part of the Free-Roaming Horses and Burros Act, which declares the animals “living symbols of the historic and pioneer spirit of the west.”
Currently, the animals are rounded up every three years and given various treatments, one being a contraceptive. The contraceptive is in the form of a vaccine that contains porcine zona pellucida (PZP), which inhibits pregnancy by stimulating the creation of antibodies that prevent sperm from attaching to eggs….the propaganda continues here: http://equusmagazine.com/blog/ohio-state-veterinarian-pzp-contraceptive-wild-horses-blm-53121#sthash.9tN9nbJ4.dpuf
