Dec 15, 2015 — “While touted as a ‘vaccine,’ porcine zona pellucida — PZP — is actually a perversion of a vaccine — an anti-vaccine — whose mode-of-action is to cause auto-immune disease. PZP tricks the immune system into producing antibodies that attack the ovaries, inducing ovarian dystrophy, oophoritis (inflammation of the ovaries), and ovarian cysts. Worse yet, per radioimmunoassay, the PZP antibodies are transferred from mother to young via the placenta and milk. The antibodies cross-react with and bind to the zonae pellucidae of female offspring. Although hyped as a ‘non-hormonal’ method of birth control, PZP causes estrogen levels to plummet as the ovaries degenerate. Despite the manufacturer’s claim that PZP is ‘reversible,’ its effects wear off unpredictably. In herds under PZP ‘management,’ the birthing season extends to nearly year-round, putting the life of the foals and mares at risk. Because PZP messes with the immune system, it ‘works’ best on the healthiest fillies and mares — those with strong immunity — ironically, rendering them sterile even with just a few treatments. Fillies injected with PZP before they have reached puberty are particularly vulnerable to immediate sterilization. Conversely, PZP has little to no effect on fillies and mares with a weak immune system — they continue to become pregnant. Thus, a herd being treated with PZP is undergoing selective breeding for low immunity, which puts the population at risk for disease — and ultimately, extinction.” ~Marybeth Devlin, member of The Facebook Forum on PZP for Wild Horses and Burros.

Comments on BLM’s Plan to Extend Infertility Drug Use through 2015 Due by September 16th
Dear Cloud Supporters;
Mark your calendars. Comments regarding a five-year plan to continue the use of Porcine Zona Pellucida (PZP) infertility drugs on Pryor wild horse mares are due on September 16. The initial scoping letter from the Billings BLM was mailed on August 18.
As a result of aggressive infertility applications delivered via shots last fall and dart guns this spring, 52 mares on the mountain are cycling monthly (coming into estrous or heat), being bred, and defended by their band stallions.
Makendra and I were in the Pryors last week for 5 days and I witnessed more societal disruption than I have seen in over 16 years of documenting these horses. Currently, it is a herd in chaos. 60% of the 18 bands we observed have had some kind of disruption. Three band stallions have lost their families all together. Some band stallions have benefitted from the intense competition — like Cloud, who won a new mare. This high degree of disruption has taken place just since our last visit in July.
