U.S. House Approves Measure that Mandates BLM to Administer Humane Fertility Control, PZP, on Wild Horses
The effort to require the Bureau of Land Management to implement a humane management strategy for America's wild horses with the immunocontraception, porcine zona pellucida (PZP), advanced through a FY21 U.S. House spending bill.
Rep. Steve Cohen (D-TN) offered an amendment to the “State, Foreign Operations, Agriculture, Rural Development, Interior, Environment, Military Construction, and Veterans Affairs Appropriations Act”, which would mandate that at least $11M of the Bureau of Land Management’s FY21 wild horse and burro budget be allocated to administering PZP to mustangs on the range.
Cosponsors of Cohen's amendment:
U.S. Representatives; Dina Titus (D-NM), Raul Grijalva (D-AZ), Joe Neguse (D-CO), Brian Fitzpatrick (R-PA), David Schweikert (R-AZ), David Price (D-NC), Peter King (R-NY), Deb Haaland (D-NM), John Katko (R-NY), Jan Schakowsky (D-IL), and Ben McAdams (D-UT).
By a vast majority, the U.S. House passed the amendment, but it did meet with one outspoken voice of opposition: Rep. Chris Stewart (R-UT). Stewart, who is a leading architect of the misguided and reckless, “Path Forward, 10 Years to AML agenda” for wild horses, decried the amendment. He stated on the U.S. House Floor, "While I appreciate the gentleman's concern for wild horses, it will end up hurting more than it helps." Stewart went on to say, “The amendment seeks to push PZP contraceptive. The only problem with that is it doesn't work.”
Rep. Chris Stewart (R-UT) opposes humane fertility control, PZP, for wild horses.
It’s extremely troubling that Rep. Stewart attempted to sabotage the amendment, especially as his 10 Years to AML agenda partners include the Humane Society of the United States (HSUS), American Society for the Prevention of Cruelty to Animals (ASPCA), and Return to Freedom (RTF). All three of these organizations support the use of PZP. In fact, HSUS holds the registrant for PZP under the name “ZonaStat-H” for use on wild horses and burros, ASPCA has provided financial support for PZP research and development, and RTF successfully utilizes PZP on the wild horses residing at their sanctuary.
The next hurdle for the $11M mandate on PZP use will be in the U.S. Senate's FY 2021 spending bill that will be drafted and voted on in the next few months.
The Trump administration plans to test a single-dose birth-control vaccine that could help control growing wild horse and burro herds. At issue is a research project that would be conducted by the Bureau of Land Management and the Agriculture Department to test the one-dose oocyte growth factor vaccine on about 16 mares that have already been removed from overcrowded federal rangelands.
BLM says the vaccine holds the promise of rendering mares infertile for three years or longer. Currently, the most common birth-control vaccine for wild horse populations is porcine zona pellucida, or PZP, which lasts for only about a year and requires multiple doses.
BLM late Friday issued a final environmental assessment and decision record signed by BLM Nevada Director Jon Raby advancing the plan. The decision is open for administrative protests for 30 days.
BLM estimates there are more than 88,000 wild horses and burros trampling federal herd management areas — more than three times the number of animals the rangelands can sustain without damaging vegetation, soils and other resources.
The final EA and decision record follow President Trump's fiscal 2021 budget request last month that referred to wild horses and burros as an "existential threat" to the health of federal rangelands. It asks Congress for an additional $15 million to take steps to increase roundups and fund research for more effective methods of sterilization and birth-control techniques
If successful, the one-dose vaccine by itself would not be enough to reduce herds to appropriate management levels. But it would help to control populations once they have reached sustainable levels.
The USDA Animal and Plant Health Inspection Service's National Wildlife Research Center, which will partner with BLM on the one-dose study, has tested a different version of the proposed vaccine. It required multiple doses but lasted two years.
If the latest one-dose vaccine proves effective, BLM will still need to go through a "separate decision-making process" and site-specific analysis before using it on wild horses on the range, the final EA says.
The plan to test 16 mares — currently being held at the Northern Nevada Correctional Center in Carson City, Nev., as part of an inmate program to train the wild horses for adoption — includes a provision to study the behavior of the treated mares for three years against a "control" group of 16 untreated mares.
Meanwhile, there is no shortage of calls for action. One of the latest comes from Utah Sen. Mike Lee (R), who is proposing that Congress allow the Interior Department to take dramatic steps to reduce wild horse and burro herds on federal rangelands.
Lee wants to allow the Interior secretary to exempt the use of helicopters and other motorized vehicles in animal roundups from National Environmental Policy Act requirements. He also wants to waive NEPA mandates regarding sterilization of the animals, as long as the procedure is performed by a "licensed professional."
Lee's proposal is included in an amendment to a broader energy package led by Senate Energy and Natural Resources Chairwoman Lisa Murkowski (R-Alaska) and the committee's ranking Democrat, Sen. Joe Manchin of West Virginia. The full Senate is expected to vote on the package this week.
Lee's amendment, which is not expected to be approved, would allow the NEPA waiver after the secretary determines "that an overpopulation of wild free-roaming horses or burros exists on a given area of public land, and that action is necessary to remove excess horses or burros."

A synopsis of a presentation to veterinarians during The American Mustang session at the 2014 American Association of Equine Practitioners Convention, held Dec. 6-10 in Salt Lake City, Utah.
Feral tribal horses walk the streets within the Navajo Nation. They’re outside restaurants. In people’s yards. There are just too many horses, and the Navajo government is working to change that. It started in 2013 with community roundups and a veterinary management program.
Scott Bender, DVM, works as tribal veterinarian with the Navajo Nation Veterinary Program and is a USDA Animal and Plant Health Inspection Service consulting veterinarian. At the 2014 American Association of Equine Practitioners Convention, held Dec. 6-10 in Salt Lake City, Utah, Bender shared the challenges faced when managing feral horses within the Navajo Nation and results of tribal equine population management efforts.
The Navajo Nation is located in the southwestern United States, with territory spanning Arizona, Utah, and New Mexico. The reservation comprises 18 million acres and, said Bender, an estimated 75,000 to 96,000 horses.
The tribe permits 12,000 livestock owners, with the majority of permit holders having one to five privately owned horses.
Under tribal law, all unbranded horses within the Navajo Nation are tribal property, Bender explained. That leaves the tribe with a lot of horses.
The Navajo traditionally view horses as sport, working, and food animals. “The horse is sacred to the Navajo, but that doesn't mean we don't eat them," Bender explained. The Navajo believe horsemeat has medicinal, healing properties and is useful as a “winter” meat, he said, explaining that “horsemeat, by tradition, can only be eaten in the winter between October and April—end of thunder and not after ‘first thunder.’”
Initially and into the early 20th Century, the U.S. Bureau of Indian Affairs managed tribal livestock, but management has slowly transitioned to the sovereign nation government, Bender said. This happened partly because of U.S. government-approved reduction of livestock in the 1930s and the euthanasia and burial of more than 500 horses by federal authorizes following a dourine outbreak at the Canyon de Chelly National Monument, which is located in northeastern Arizona within the Navajo Nation boundaries. “This ‘waste of resources’ has left a negative indelible mark on the attitude of Navajo livestock owners toward the U.S. government,” Bender said.
To the Navajo, unused horsemeat is a wasted resource that the creator gave the people, he clarified.
With this in mind, surplus Navajo horses had historically been sold off-reservation to slaughter as a way to manage populations and produce income. When U.S. equine slaughter plants closed in 2007, the tribal horses lost 95% of their value and the surplus feral horses were left to breed without human controls, Bender said. “The current (tribal) horse issue is a direct result of the elimination of an outlet for surplus horses,” he added.
As herds grew, damage to rangelands increased, as did horse-caused human injuries. “Horses in right-of-ways caused car wrecks, human injuries, and even deaths,” Bender said. These issues led tribal communities to request that the Navajo National Department of Agriculture start its equine population management program in 2013, which involved roundups and veterinary services, including free:
While the initial fertility vaccination was effective, Bender described owner booster rates of horses as “dismal,” despite the program’s outreach and communications efforts promoting boosters. The program’s leadership is now investigating anti-gonadotropin-releasing hormone vaccine (know more commonly as anti-GnRH or GonaCon) use as a longer-activing and single-dose alternative to PZP.
In 2013 the Navajo Nation local communities, with the help of the Navajo Nation Departments of Agriculture and Resource Enforcement, rounded up more than 8,900 horses. Permitted owners claimed approximately 250 horses, with the tribe selling the rest with the requirement that they could not be returned to the Navajo Nation.
The veterinary program’s goal was to castrate 1,000 male horses and vaccinate 1,500 mares against fertility by the end of 2014. To date, more than 700 horses have been castrated or vaccinated with PZP for fertility control. Bender said members of communities where horse removals took place have reported improved forage conditions in spite of the continuing 14 years of drought in the southwestern United States and Navajo Nation.
