Perverted Darting with Pesticide PZP

10 things you need to know about Pesticide PZP

1. PZP — The Pesticide: PZP is an EPA-registered pesticide manufactured from the ovaries of slaughtered pigs. Some persons argue that, because PZP does not kill the mare, it is not really a “pesticide.” Actually, PZP does kill. Stillbirths are associated with the pesticide’s use, meaning that some of its supposed contraceptive effects are actually feticidal.. In addition, over the long term, PZP weakens a herd immunologically, putting it at risk for eventual or even sudden extinction.

2. PZP — The Disproved Hypothesis: PZP’s manufacturer promoted the product as generating antibodies that “block sperm attachment.” But that marketing-hype was merely an untested hypothesis postulated three decades ago. Independent researchers found that PZP has a different effect, and many adverse effects.

3. PZP — The Actual Mode-of-Action: Behaving like a perverted vaccine, PZP tricks the mare’s immune system into making antibodies that cause ovarian dystrophy, autoimmune oophoritis, ovarian cysts, and premature ovarian failure. PZP quickly sterilizes mares that have a strong immune system but has no effect on those suffering from weak immunity. Thus, PZP both works and doesn’t work but, in the long run, selects for poor immune function. Weak immunity = weak resistance to infection, which could quickly wipe out a herd. PZP also affects the foals. If a mare is pregnant or nursing when darted, PZP antibodies are transferred to her offspring via the placenta and her milk. So, inadvertently, unborn and newborn foals receive a dose or two of the pesticide when their dams are injected.

4. PZP — The Danger to Humans: PZP is a powerful endocrine-disruptor. It causes a sharp drop in estrogen levels. Unfortunately, because the manufacturer misrepresented PZP as “so safe it is boring,” volunteer-darters have become lax in following safety-precautions. Accidental self-injection could result in severe adverse effects because the dose-in-question is sized for a horse.

5. PZP — The Year-Round Birthing-Season: A longitudinal study (Ransom et al. 2013) of three herds currently under treatment with PZP found that the the birthing-season lasts virtually year-round (341 days). Out-of-season births put the life of mares and their foals in jeopardy. Nature designed foals to be born in Spring, not year-round, and certainly not in Winter.

6. PZP — Prolonged Delay in Recovery of Fertility: Ransom et al. also found that, after suspension of PZP, it takes more than a year per each year-of-treatment before mares recover their fertility. PZP’s manufacturer conceded that it could take up to 8 years to recover fertility after just 3 consecutive years of PZP treatment.

7. PZP — Scientists Say Proceed with Caution: Ransom et al. warned: “The transient nature of … PZP can manifest into extraordinary persistence of infertility with repeated vaccinations, and ultimately can alter birth phenology in horses. This persistence … suggests caution for use in small refugia ….”

8. PZP — Contraindicated for Tiny, Isolated Herds: Several years ago, BLM convened a meeting of scientists on the topic of minimum herd-size for genetic fitness. Conclusion: “Smaller, isolated populations (<200 total census size) are particularly vulnerable ….” And that’s without PZP in the mix.

9. Slow Herd-Growth: Per independent research, wild-horse herds increase at a rate of only 5% a year; and wild-burro herds, just 2%. Such slow growth does not warrant pesticide treatments administered en masse every year. Eventual sterilization is inevitable, with extinction of the herd over the long term.

10. Predators: The right way to right-size the wild-horse population is Nature’s way — predators. But those predators — mountain lions, bears, wolves, and coyotes — are persecuted mercilessly. Wildlife Services exterminates what trophy-hunters don’t shoot. Predators help the herds by favoring survival-of-the-fittest and the best genetic adaptations. Predators are the “no-cost” solution.

International News: American wild horse advocates seek freeze on roundups

New Zealand paper reports: 

The Bureau of Land Management is wiping out America’s wild horses,” says Anne Novak, executive director of the group. “We need to stop the roundups and protect our native wild horses.”

Protect Mustangs described the appropriate herd management level of 138 for the area as out of date and lacking in scientific merit.

“We must ensure native wild horses can survive upcoming environmental changes,” Novak says.

“The minimum population for a genetically variable herd is 150. Why are PZP advocates and the BLM allowing wild horse herds to fall below safe numbers?”

PZP advocates put wild horses at risk of sterilization after roundup

Stop the Roundups!

Protect Mustangs calls for a freeze on roundups for scientific reevaluation

Tonopah, NV (October 31, 2014)–The Battle Mountain District, Tonopah Field Office is rounding up about 120 wild horses from within the Reveille Allotment and Herd Management Area (HMA) located approximately 50 miles east of Tonopah, NV to remove alleged excess wild horses on 600,000 acres of public land.

“The BLM is wiping out America’s wild horses and taxpayers are paying for the abuse,” states Anne Novak, executive director of Protect Mustangs. “We need to stop the roundups and protect our native wild horses.”

The roundup will stampede native wild horse families by helicopter over a fragile ecosystem and possible sage grouse habitat in the Great Basin Desert. Often wild horses are injured and die in roundups. The treacherous roundup is paid for with tax dollars, and began October 30, 2014. Most herds need to be rounded up before given PZP.

After the roundup, approximately 70 wild horses will be permanently removed, 60 wild horses will be sent to holding facilities in Ridgecrest, California and about 10 horses will be offered for adoption after the roundup in Tonopah, NV on November 8. The remaining 50 wild horses will be released back into the HMA for a post roundup population of 98 wild horses, putting the survivors at risk. The minimum number for genetic variability is 150 wild horses.

Often the BLM returns wild horses with conformation defects to the range, instead of placing them in adoptive homes or long-term holding where they will not breed. Apparently the agency doesn’t realize that by returning wild horses with defects they will ruin the breeding pool. The BLM claims mares selected to maintain herd characteristics will be released back to the HMA. The public must watchdog the agency to ensure wild horses with defects are pulled from the breeding pool and rehomed. Euthanizing them is not an option supported by the American public.

The informed public is outraged over an EPA approved restricted use pesticide called PZP, made from pigs ovaries, to be used on native wild horses. PZP advocates campaign rigorously to treat mares with the Porcine Zona Pellucidae (PZP-22) in order to temporarily sterilize mares. PZP advocates hail the use of PZP in spite of the fact that wild horses are underpopulated on millions of acres of public land.

Experimental research on ovary damage in mares given the immunocontraceptive PZP is used to hone the drug for eventual human use. This could be where the “follow the money” piece fits in. Wild horse advocates are furious America’s herds are being used as lab rats. Science has proven the drug sterilizes wild horses after multiple use. PZP advocates are pushing for BLM to manage wild horses “in the wild” using these risky drugs.

The devastation of wild horses in the Reveille Allotment appears to be subject to a 1987 District Court Order and two orders issued by the Interior Board of Land Appeals (IBLA) in 2001 and 2002, requiring BLM conduct an annual inventory of wild horses in the Reveille Allotment and initiate a roundup to remove alleged excess native horses from the Allotment when the inventory shows that population numbers exceed the out of date Appropriate Management Level (AML) of 138 horses.

Current AML does not represent healthy herd populations and lacks scientific merit. AML must be updated to ensure healthy herds remain on public land. The herd census must never fall below 150 wild horses to maintain genetic variability.

The current estimated population, based on previous inventory flights is 168 wild horses, according to BLM. This is the low end of the genetic viability scale. The orders need to be challenged based on scientific reevaluation of wild horses benefiting the ecosystem as a native species, livestock causing range damage and the minimum number of wild horses needed for genetic variability.

“We must ensure native wild horses can survive upcoming environmental changes,” states Anne Novak, executive director of Protect Mustangs. “The minimum population for a genetically variable herd is 150. Why are PZP advocates and the BLM allowing wild horse herds to fall below safe numbers?”

According to a press release from National Academy of Sciences (NAS) released June 5, 2013, “The U.S. Bureau of Land Management’s (BLM) current practice of removing free-ranging horses from public lands promotes a high population growth rate, and maintaining them in long-term holding facilities is both economically unsustainable and incongruent with public expectations,” says a new report by the National Research Council.

The NAS report states there is “no evidence” of overpopulation. Only tobacco science and spin backs up BLM’s population claim to justify roundups and fertility control/sterilizations. PZP advocates lobbied NAS to have fertility control recommended even though the herds are underpopulated.

Roundup activities within the Reveille HMA were analyzed in the 2010 Reveille HMA Wild Horse Gather Plan and Environmental Assessment (EA) and the 2014 Reveille Wild Horse Gather Determination of NEPA Adequacy (DNA). The EA, DNA, and Decision Record can be accessed on the Reveille Wild Horse Gather website: http://on.doi.gov/10qLBlh.

Members of the public are encouraged to witness the helicopter stampede and document America’s icons losing their freedom to spread awareness that cruel roundups must stop. Observation protocols and visitor information are available at http://on.doi.gov/1xAMeTp. The BLM will post updates, photos and other information about the roundup on the Reveille website and on the hotline at 775-861-6700 throughout the course of the roundup.

The BLM is wiping out wild horses for the extractive industry and New Energy Frontier in the West. The agency manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM focuses on their mandate of multiple-use and sustained yield. In Fiscal Year 2013, the BLM generated $4.7 billion in receipts from public lands.

BLM’s roundups disturb the thriving natural ecological balance by disturbing habitat dynamics. This crime against nature causes abnormally high birthrate and puts native wild horses at risk of inbreeding.

“We are calling for an immediate freeze on roundups and removals for scientific reevaluation,” states Novak. “Right now native wild horses are at risk of being ruined by bad policy.”

Protect Mustangs is a nonprofit organization dedicated to the conservation of native and wild horses. The group is against using PZP in the wild. Today most wild herds are threatened with low numbers and a lack of genetic variability. Using PZP in a sanctuary setting where acreage is limited is a different situation. Wild horses must not be managed in the wild as if they were a zoo exhibit.

Press Release: How many tiny foals are dying after the roundups and in holding?

MUSTANG Captured Young Wild Horses Dec 27, 2010

For immediate release:

No accountability for dead foals at Nevada wild horse facility  

RENO, Nv. (May 1, 2013)–Protect Mustangs™ calls for the Bureau of Land Management (BLM) in Nevada to provide accurate wild horse and burro death counts for all government funded facilities as well as at roundups. Currently the BLM is not recording the dead foals or other unbranded newborn dead wild horses at the Palomino Valley National Center, a facility near Reno used for processing and adoption. Faulty roundup protocol also allows the BLM to attribute deaths to pre-existing conditions to avoid attributing them to the roundups. The native wild horse conservation group discovered that 37 wild horses died at the Nevada facility from January 1 to April 1, 2013 but the additional deaths of the unbranded have gone unrecorded.

“It’s shocking that the BLM is not counting the unbranded dead foals and dead newborns,” states Anne Novak, executive director of Protect Mustangs™. “This lack of transparency and lack of accountability needs to stop. Taxpayers don’t like knowing baby mustangs are dying after roundups–especially when Americans want native wild horses to live in freedom.”

Protect Mustangs™ is very concerned the BLM facilities are not keeping an accurate death count related to roundups and holding facilities. The BLM admits they are not including the unbranded foals, aborted fetuses, animals born dead nor dead newborns in their count. One must ask, “How many are really dying in holding facilities after roundups?

Animals Angels recently uncovered a discrepancy in the mortality numbers at Palomino Valley Center.

“If they are not counting the dead correctly then are some young foals being sold into the slaughter pipeline as well?,” asks Novak. “Why is there no accountability regarding the unbranded young wild horse population?”

Tom Davis, who purchased many wild horses from the BLM said in a Propublica interview, “Hell, some of the finest meat you will ever eat is a fat yearling colt. What is wrong with taking all those BLM horses they got all fat and shiny and setting up a kill plant?”
