The open forum on PZP for federally protected equids is held on Facebook here and everyone is welcome: https://www.facebook.com/groups/ForumPZPWildHorsesBurros/

Statement:

“If the good people of Nevada choose to use PZP to manage their wild horses on state land it’s up to them because that is a state issue. Americans across the country are concerned PZP isn’t safe and don’t want their wild horses and burros on federal land to be given the restricted-use pesticide hailed as “birth control” but known to sterilize after multiple use. If PZP advocates can prove PZP is 100% safe for native wild horse and burro herds, won’t sterilize them, ruin genetic variability or cause behavioral abnormalities then it could be considered as a management tool. Until then other holistic management tools must be examined. It’s time for a freeze on roundups, drugging and removals for scientific reevaluation. We need to get it right for our icons of American freedom.” ~ Anne Novak, Executive Director of Protect Mustangs

RE: Pryor Mountain Wild Horse Range Fertility Control Preliminary Environmental
Assessment Tiered to the Pryor Mountain Wild Horse Range Environmental Assessment and Herd Management Area Plan May 2009 EA DOI-BLM-MT-0010-2011-0004-EA

Dear Jared Bybee:

Background

I appreciate the opportunity to submit comments on the Pryor Mountain Wild Horse Range
Fertility Control Preliminary Environmental Assessment Tiered to the Pryor Mountain Wild
Horse Range Environmental Assessment and Herd Management Area Plan May 2009 EA DOI-BLM-MT-0010-2011-0004-EA. My background is in equine reproductive immunology and wildlife conservation. I applaud the Billings Field Office of the Bureau of Land Management (BLM) for a thoughtful approach to this issue. Cover letter 4700 (010.JB) dated November 2010 and signed by James M. Sparks, Field Manager states that the BLM would consider comments and revision to the EA or unsigned FONSI as appropriate. I urge a “no action alternative” as outlined on page 7 and 8 of the EA. This request is based on two pieces of new scientific evidence about effects of current immuno-contraception use.

Porcine Zona Pellucida (PZP) Contraception

The proposed action as stated on page 7 of this EA would exempt “mares ages 5-10 unless they have produced foals, or are part of a large bloodline.” This is reminiscent of the approach taken with the Assateague Island wild horse population. It is a compromise approach to this issue, in comparison to placing all mares on PZP. However a recent study shows that mitochondrial DNA diversity is low in the Assateague Island horse herd (Eggert et al. 2010). Since mitochondrial DNA is inherited from the mother (mare), this is evidence that female inherited genetics on Assateague Island wild horses is under represented. It is imperative that this be assessed before rolling out a similar management plan for the Pryor Mountain wild horses.

There is a recent Princeton University study on PZP effects. Consecutive PZP applications, analogous to the proposed action plan in this EA, showed that mares gave birth later in the season, and were cycling into the fall months (Nunez et al. 2010). In a state like Montana where freezing temperatures are found in the fall, this can have serious and long term effects on foal survivorship.

I must include a statement on long term consecutive use of PZP. Any form of PZP contraception is not completely reversible in mares depending on the length of use of PZP. Contraception can only be reversed when the antibody titer decreases to 50-60% of the positive reference sera (Liu et al. 2005). Mares treated for 7 consecutive years do not return to viable fertility (Kirkpatrick and Turner 2002; Kirkpatrick et al. 2009). The issue of reversible contraception is very important to be able to maintain wild equines in the United States. Long term treatment with PZP has inherent negative potential for this herd.

I am requesting a new look at the proposed fertility control action for the Pryor Mountain wild horses.

Sincerely,

Bogus Science and Profiteering Stampeding Their Way into Wild Horse Country

 

PM Jaime Jackson

A Review of Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward (2013)

by Jaime Jackson, AANHCP Executive Director

I’ve reviewed the entire 300+ page National Academy of Sciences report—clearly a major undertaking by all the scientists involved and a bit of a “heavy” read—including its academic findings and recommendations (“A Way Forward”) which are, in the end, woefully predictable. Thinking about it, however, the scientists who created the report really had no choice, given the limits of the Wild, Free-roaming and Burro Act itself, if we are to accept that, but to work within its boundaries and the conundrum set upon them by that law’s specious political and land management premise and somehow respond to the task put upon them by the BLM. Clearer and more honest minds might have said, “I want no part of such a nasty, skewed project.” I also gleaned the biographies of each scientist to see what kind of understanding they would bring to the table regarding horse care based on their education and training, and if they seem like “clear minded” thinkers who could think outside the box in the best interest of any horse. On that note alone, wild horses are in trouble.

Because the “limits” put upon the NAS committee by the wild horse law are what they are, and because these are basically mainstream scientists drawn out of academia, it is entirely logical that they would recommend regulating wild horse and burro populations, in their words, “with science”. But what kind of science, one might ask? Well, the fact is, it’s the same brand of science, and scien- tific minds in today’s academia, that has failed the domesticated horse. We’re talking about scientists who serve the special interests of government and its lobbyists, the agricultural and pharmaceutical industries, and so forth, that have given us drugs and feeds and management practices that cause laminitis and other metabolic breakdowns of the horse. Indeed, it is all profitable for the very community that has created this “science based” disaster for horses. I’m not just spewing words here without foundation, horses truly suffer for it, and it is this bad science and corresponding harmful equine management practices that have given birth to and fueled the internationally burgeoning NHC movement. That is a fact—and it is a fact also that these scientists, and the special interests that fund them, refuse to acknowledge NHC because what we do and advocate for gets directly to the bottom of ethics and profiteering and inbred academic close-mindedness.

The authors of this NAS report have very skillfully woven together what is genuinely good sci- ence with the bad, while ignoring other good science altogether—all to the end of supporting the bogus proposition that their brand of “science” favors a lasting solution for wild horse management. If one reads their report carefully, however, one can sense the palpable excitement and impatience behind their drug-based recommendations. For example, they urge the BLM to step up an accurate numbers count in the HMAs (which, arguably, given that agency’s past, can never be trusted) because, they suggest, the quantities of PZP and other pharmaceutical agents needed to cleanse wild horse country will surely be vastly greater than what was used in their scientifically con- taminated control study done to the Assateague ponies of the U.S. east coast (cited in their re- port). Assateague was not good science, anymore than what has happened to those horses long before the government’s study. It catered to the drug industry and the same eugenics science that the U.S. and British governments sanctioned and used against people during the greater part of the 20th century (up to the 1960s and 70s), and that was astutely “borrowed” from by Nazi Germany for its extermination campaigns to “rid the world of undesirables”.

Just as tactfully, and just as predictably, the NAS authors stated that predation behavior was not viable, ignoring Drs. Turner and Morrow’s mountain lion predations studies referenced in my books, The Natural Horse and Paddock Paradise, and which proved the viability of natural predation on wild horse herds. Of course, the reason that natural mountain lion and wolf predation won’t work, and which the NAS report fails to explain, is because BLM management practices have provided for their extermination and/or removal under welfare ranching pressure that deflects the truth of what’s happening within their grandfathered land leases born of the Taylor Grazing Act and the BLM’s inception.

I could easily go on, and on, and on, nit picking the massive tangled NAS report, but would just be wasting my time and yours with the report’s self-serving “word salad”. The fact is, there is no genuine solution in their report that respects the natural integrity of America’s wild, free- roaming horses. And there is no debating the authors of the report either, for they are completely sold out to the very special interests who have never seen value in our wild horses. In fact, it is the science community that has recently aided and abetted the government in reclassifying wild horses legally as “pests” so that the pesticide PZP can be used on them for birth control purposes. You see, the NAS report is no surprise, as its convoluted “commandments” have been systematically orchestrated and colluded with by just about everyone in sight, including—and I am sad to say—nearly every purported “wild horse protection” group and sanctuary in the United States. Many of these groups stand to “gain” from this collusion, including the HSUS that co-owns patent rights to PZP.

Tax payers can expect to pay more, not less, as they watch their wild horse herds deteriorate genetically under the government’s Nazification of the HMAs through racism-based eugenics. This is because there is profit motive at its foundation. In fact, the report cautions that “public confidence” and trust will be an important part of the “master solution”. Inundating tax payers with scientific “word salad” that few can understand, is understood. Clearly, the public does not understand the underlying issues, except what they hear in the news. From that vantage point, this does not bode well for our wild horses.

What is needed is a new vision and a new law for genuine wild horse preservation. The current law is bankrupt and offers no real protection, let alone preservation. Science, industry and the big government have joined claws and are at war with Natural Selection, because they are losing—and they know it. And, it is for this reason, that Science is now being called upon to step up the delusion that the war on nature can and will be won. Like the war on cancer, no such victory is forthcoming. But because the war is profit driven, the war is welcome. Read the NAS report with a critical eye, and you will see this. In the end, HMAs will become zoos with GMO wild horses. Like those we see in the wild horse protectionist’s “sanctuaries”: sad, pathetic parodies of real wild horses. Is this what the public envisioned when it stood behind the original wild horse protection law? Of course not. but, here today, government and science and industry (and its camp following ersatz wild horse protectionists begging for crumbs), all hand in hand, are going to exploit wild horses and unwitting taxpayers for what they can—until, at long last, nature has proven them wrong, and the deceptive game is exposed for all to see. The Assateague model, which they will cite and hold up, is a broken one. But they are counting on an uninformed public to buy into it. Those of us in the NHC movement know better and can refute it with facts by simply looking at the hooves of those horses, if not the non-adaptative environment they are squeezed into be- cause of an historical fluke. Looking through the bios of the NAS committee members, I seriously doubt that any of them would have a clue of what I’m talking about.

The Obama Administration, as much of the voting public on both sides of the aisle have come to realize, is a compromised, “sold out to big industry” travesty that is going to stand be- hind the eugenics science and land grab scheme fully intended to bilk the taxpayer and pad the pockets of profiteers who, quite frankly, don’t give a damn about wild horses. That includes Sally Jewell, Obama’s hand-picked clone of Ken Salazar to head the Department of the Interior (BLM’s overseer), who is no friend of the wild horse or any horse. She came right out of big banking and the oil industry. Check out her bio on her DOI government website. She will go right along with “big science” because that is where the money is and because, the fact is (and it is not rocket science to figure it out), it will lead to the decimation of wild horse herds. James Kleinert’s film “Wild Horses and Renegades” draws a direct line between Jewell, “wild horse pests” and their extermination, and the land grab now going on in BLM country by big industries such as BP and backed by the Obama Administration.

Let me put it in simple terms — it’s just a matter of time before they’re shoeing wild horses in the HMAs! If you don’t want that, support the AANHCP’s vision for genuine, lasting wild horse protection and taxpayer relief.

PZP EPA Sterilisant

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.

Science proves PZP is sterilizing wild horses

The truth

The Effects of Porcine Zona Pellucida Immunocontraception on Health and Behavior of Feral Horses (Equus caballus)

Authors: Knight, Colleen M.
Advisors: Rubenstein, Daniel I.
Department: Ecology and Evolutionary Biology

The horse population on Shackleford Banks, a barrier island off the coast of North Carolina, has been controlled using a program of porcine zona pellucida immunocontraception since 2000. Prior studies found no negative physiological effects of the immunization, but suggested some adverse effects on behavior such as increased harem switching and extended reproductive season. Although no mares were immunized in the year of study (2013), we examined the effects of past contraception and foaling on health and behavior of the mares in an attempt to better understand its impacts on both the individual and the population. Current lactation was found to be the best predictor of health and behavior: lactating mares were in worse physical condition, spent more time grazing, and switched harems fewer times. Mares that had never foaled also were in better physical condition than mares that had foaled in the past, but did not differ in behavioral measures. There were indications that the PZP treatment has had effects other than preventing pregnancy: an increased number of years since immunization was correlated with better body condition and fewer harem switches, independent of lactation. Contraception treatment intensity or timing did not have any significant adverse effects on health and behavior on its own. However, three or more consecutive years of treatment or administration of the first dose before sexual maturity may have triggered infertility in some mares. Inducing sterility, while relieving the mares from the energetic costs of lactation and reducing the stress from harem switching, may have unintended consequences on population dynamics by increasing longevity and eliminating the mares’ ability to contribute genetically.

PZP is an EPA approved restricted use pesticide and Protect Mustangs is against using it on wild mares especially when there is an underpopulation problem on public land despite government spin. The truth is most wild herds are being threatened with low numbers and a lack of genetic variability.

Controversy over PZP

Ken Salazar’s Wild Horse Plan Fuels Accusations That He’s In The Pocket Of Ranchers, Associated Press, 2010: http://www.huffingtonpost.com/2009/10/17/ken-salazars-wild-horse-p_n_324799.html

Wildlife ecologist Craig Downer of Nevada accused Salazar, a former rancher, of acting on behalf of those who view mustangs as taking scarce forage away from their cattle herds. Downer contends cattle are more destructive to the range because they concentrate in high numbers around water sources instead of grazing over a wider area as wild horses do.

“Both the Forest Service and the Bureau of Land Management have the right to remove livestock to ensure viable, healthy populations of wild horses. But they refuse to exercise that,” Downer said. “Their master is primarily these traditional ranching interests.”

Opposition grows to Salazar’s plan to move wild horses to Midwest preserves, Associated Press 2009http://www.oregonlive.com/news/index.ssf/2009/12/opposition_grows_to_salazars_p.html

Horse defenders have stepped up their efforts in recent weeks, suing to block a proposed roundup of 2,700 horses in northern Nevada and lining up the support of celebrities such as Sheryl Crow, Lily Tomlin, Bill Maher and Ed Harris.

Crow took her concerns directly to Salazar in a telephone call this past week.

One of the first things he said was something must be done because the horses are starving. We (advocates) don’t believe it,” Crow said in an interview with The Associated Press.”

7 Preserves Envisioned to Manage Wild Horses, New York Times, 2009http://www.nytimes.com/2009/10/08/us/08horses.html?_r=0

“HELENA, Mont. — Interior Secretary Ken Salazar said Wednesday that he was proposing to create seven new wild-horse preserves, including one in the East and one in the Midwest, to address the problem of a growing population crowding the Western range.

The program, which also applies to wild burros, would expand the use of contraceptives and would geld more herds on public lands in the West, Mr. Salazar said.”

. . . ”

Yet the proposal quickly drew criticism from wild-horse advocates. Ginger Kathrens of Colorado Springs, a maker of documentary films who has chronicled the lives of a wild-horse herd in Montana, said that blocking reproduction could alter the animals’ behavior.

“It takes the wild out of wild-horse herds,” she said. “They’re families in sophisticated societies. Creating gelding herds and preventing them from reproducing is managing them toward extinction.”

But ranchers, who see wild horses as competing with cattle for grasses and water, welcomed the proposal. Jeff Eisenberg, executive director for the Public Lands Council, a group that works on public lands issues for ranchers, said Mr. Salazar’s proposal was a big step toward a solution.”

Sheryl Crow Slams Salazar’s Wild Horse Plan, Huffington Post 2010http://www.huffingtonpost.com/2009/11/22/sheryl-crow-slams-salazar_n_366809.html

With one voice we are insisting that our government stop managing these beautiful and important animals to extinction,” Crow said in a statement released by the Cloud Foundation, a Colorado Springs, Colo.-based horse advocacy group”. . .

It’s time for all of us to speak up for our wild horses and burros so we do not lose these living legends and inspiring symbols of our freedom in America,” she said.

Madeleine Pickens praises Salazar wild horse plan, Horsetalk, 2009http://www.horsetalk.co.nz/news/2009/10/077.shtml#axzz3HKN0uSuY

“Interior Secretary Ken Salazar announced wide-ranging proposals this week in which horses taken from the Western rangelands would be relocated to new preservation areas further east, utilising better quality grassland.

Injection-Site Reactions in Wild Horses (Equus caballus) Receiving an Immunocontraceptive Vaccine, By James E. Roelle and Jason I. Ransom, http://pubs.usgs.gov/sir/2009/5038/

“Abnormal dart trauma included cases where the dart hit bone or the needle broke off. We found strong evidence (odds ratio = 5.023, P = 0.001) for a higher probability of occurrence of swelling when darts were delivered by blowgun. We found some evidence (odds ratio = 8.729, P = 0.07) that abnormal dart trauma led to a higher frequency of nodule formation. Nodules were the most common reactions observed and often persisted for a year or more, but in our observations they did not appear to change any animal’s range of movement or locomotor patterns and in most cases did not appear to differ in magnitude from naturally occurring injuries or scars. We were unable to perform histological examinations of these nodules, but they may be similar to granulomas reported by other investigators following administration of Freund’s adjuvant.”

Dangerous times for wild horses and burros

Dear Friends of Wild Horses and Burros,

There are several dark forces at work who want to control America’s wild horses and burros. Some want to steal them from the people so corrupt state officials can hunt and kill them or sell them to slaughter. Others want to drug them with EPA approved restricted-use pesticides such as PZP that sterilize WILD mares after multiple use. Fertility control research trials are big business. Left unchallenged, wild horses and burros will continue to be lab rats for human fertility control research. Many soulless degenerates want to slaughter wild horses for human consumption abroad. They really want to make room for energy development and subsidized grazing on public land at the expense of wildlife and especially wild horses and burros.

Be careful what you sign. Read everything carefully. Please read this petition carefully too then send it to your friends and family so the voiceless can be protected from the exploiters and the killers. If you want to know the truth behind the facade . . . follow the money.

Thank you for taking action to help America’s wild horses and burros by sharing this petition (http://www.change.org/p/defund-and-stop-the-wild-horse-burro-roundups) via email and through your social networks. Together we can shine the light on the truth to turn things around. Stop the Roundups!

Many blessings,
Anne

Native wild horses are not pests ~ Stop managing them to extinction

Dear Friends of Wild Horses and Burros

Protect Mustangs is a national nonprofit organization making grassroots count. Our mission is to protect and preserve native and wild horses. Besides engaging mostly in outreach and education about the wild horse crisis, we advocate for holistic land management, self-sustaining herds and reserve design. We are calling for a 10 year moratorium on roundups for the herds to recover from the roundups and for studies to form good management plans. Right now there are no accurate census counts on the range so we don’t even have a clear picture of the few wild horses left living in freedom.

Our members don’t see an overpopulation or “excess” of wild horses on public land, even if the population is over BLM’s biased appropriate management level (AML). Livestock outnumbers wild horses more than 50 to 1 on the range. Yet wild horses are always scapegoated for damage by special interest groups.

We are deeply concerned that the use of FDA approved “restricted use pesticides” such as PZP–an immunocontraceptive made from pig ovaries that people call birth control–sterilizes mares after multiple uses and should never be used on nonviable herds, those herds with less than 150 wild horses. Genetic diversity is essential for survival and using PZP surely will curtail that. There is one herd in Nevada currently being treated by wild horse advocates that seems to have less than 50 wild horses. This worried us.

Wild horses are a native species and not pests. Sadly there are factions who are treating wild horses as individuals and ignoring the herd element and other factions treating wild horses as invasive pests.

Despite decades of experimental research on wild mares, the FDA would not approve PZP as safe. Eventually the EPA approved it as a restricted use pesticide. You can see the pesticide fact sheet here: http://www.epa.gov/pesticides/chem_search/reg_actions/pending/fs_PC-176603_01-Jan-12.pdf

How can drugging mares with restricted use pesticides be honoring their freedom? Most of the time the BLM will need to round them up to dart them anyway. You can hear the BLM official speak about that here: http://www.thespectrum.com/videos/news/local/cedar-city/2014/08/06/13698391/

We are also concerned PZP and other sterilants affect behavior and that mares will be subjected to live in unnatural situations.

Ruining survival of the fittest and natural selection is our biggest concern if man chooses who breeds and how many foals are born. The herds must adapt to upcoming environmental and climate changes in order to survive, therefore genetic variability is essential at this pivotal time.

You can read about PZP on these various posts: http://protectmustangs.org/?s=PZP+&submit=Search

Here you can read about Gonacon on these posts: http://protectmustangs.org/?s=gonacon&submit=Search

This is also a good post to read about the ISPMB and Princeton study that shows wild horse herds with functional social structures contribute to low herd growth compared to BLM managed herds: http://protectmustangs.org/?p=6057

You can search other topics you might have questions about in our search bar too: http://protectmustangs.org

We are 100% volunteer and are working to help the wild horses without any conflict of interest as far as we can tell. We do not receive funding from influencers, corporations or organizations connected with the drug PZP, the pharmaceutical industry, Big Oil and Gas or other energy, ranching and mining sources. That’s why your donations are so important.

Our vision is to speak out for the voiceless, stop the BLM from being cruel to wild horses and work towards a solution for healthy management keeping wild horses on the range based on good science. We have a petition out for the 10 year moratorium on all roundups. Please sign and share it here: http://www.change.org/petitions/sally-jewell-urgent-grant-a-10-year-moratorium-on-wild-horse-roundups-for-recovery-and-studies

Thank you for reaching out to us. It’s important to do the research and find the answer for yourself so you can feel good about taking action to help save the last of the wild horses and burros.

We are grateful you care so deeply about saving America’s wild ones.

Many blessings,
Anne

Horse contraceptive study raises concerns

October 29, 2010
By Laurie Dixon
Research indicates the long-term horse contraceptive, porcine zona pellucida (PZP), extends the breeding season in wild horses, raising concerns over the social consequences of the drug on herds.

PZP, which is derived from pig eggs, is increasingly being used in wild horse herds . . .

Alarm over behavioral and physiological side effects of wild horse birth control (PZP)

 

 

MANAGEMENT OF WILD HORSES WITH PORCINE ZONA PELLUCIDA: HISTORY, CONSEQUENCES, AND FUTURE STRATEGIES

Cassandra M.V. Nuñez

Department of Ecology and Evolutionary Biology, Princeton University, Princeton, New Jersey

ABSTRACT

The advent of immunocontraception with porcine zona pellucida (PZP) has all but revolutionized wild horse management, providing a more humane method of population control than earlier strategies. Early studies on Assateague Island National Seashore have described it as an ideal form of fertility control in that it reduces the chance of conception to below 10%, can be delivered remotely, is reversible (after short-term use), lacks debilitating physiological side effects, cannot pass through the food chain, and shows minimal effects on social behaviors. However, recent research in other populations has revealed behavioral and physiological side effects of long-term PZP use. These results indicate that studies from one population may not necessarily be applicable to another, regardless of similarities in habitat and population structure. Careful study of the animals’ demography, physiology, and behavior is necessary prior to and during treatment to ensure that a) the potential effects of PZP can be assessed accurately, and b) within managerial constraints, PZP effects are ameliorated as much as is possible. Here I explain the history of PZP use in wild horses, its side effects on the horses of Shackleford Banks, North Carolina in comparison to other populations, and offer management suggestions based upon wild horse biology and behavioral ecology, which may minimize or prevent these side effects in other populations.
