The use of the contraceptive agent PZP can seriously compromise the natural adaptation of wild horses, writes wildlife ecologist Craig Downer. This, he suggests, subverts the true intent of the Wild Free Roaming Horses and Burros Act, passed in 1971 to safeguard the animals.
Many serious damaging effects upon wild horses and burros are caused by PZP (Porcine Zona Pellucida) administration. These effects pertain both to the mares who are injected with this inoculation, either manually when held captive or remotely by darting with a rifle in the field aimed at the hip and to the rest of the band whether stallions, other mares or young.
These effects have been documented and analyzed by professional biologists, and many ordinary people have also observed and reported them. An honest reading of the Wild Free-Roaming Horses and Burros Act (WFHBA) should reveal how out of tune PZP interference is, for it violates the most intimate parts of mares and causes an aftermath of stress, anguish and social disruption. It should be considered antithetical to this law’s core intent. Basically, PZP interference with the natural lives of the wild horses (or wild burros) is a form of domestication that contradicts the WFHBA, which mandates “minimum feasible management” and that the horses and burros be allowed to become “integral” parts of the public lands’ ecosystem where they attain a “thriving natural ecological balance”. To those who hold the noble purpose of this law in high esteem, what has and continues to happen is both a shame and a disgrace to America! This is an intolerable situation that needs to be quickly corrected…(CONTINUED)
