In 2016, the BLM attempted cruel and dangerous sterilization experiments on wild mares with Oregon State University.
Public outcry and lawsuits filed by wild horse advocacy groups like FRER helped to stop this horrific plan…but now, the BLM is at it again. With a few changes, their current proposal is similar to the gruesome plan of two years ago, but this time CO State University applied for the research grant money to participate.
Most of the wild mares will be in various stages of pregnancy. They will use a surgical procedure known as ovariectomy by colpotomy which has known high risks of pain, bleeding, infection, abortion of foals and evisceration where the intestines protrude through the surgical incision. Even the National Academy of Sciences has concluded this procedure is “inadvisable for field application”.
The surgery itself is described graphically by BLM as follows:
The surgical procedure would involve making an incision, approximately 1–3 centimeters long, in the anterior-dorsallateral vagina. Both ovaries are accessed through this one incision. The incision would be enlarged with blunt dissection to perforate the peritoneum and allow the surgeon’s hand to enter the abdomen. . . . The ovary and associated mesovarium are isolated by direct manual palpation and local anesthesia (5 ml 5% bupivacaine and 5 ml 2% lidocaine) is injected into each ovarian pedicle. . . . The ovarian pedicle would be transected with a chain ecraseur.
Given the serious risks to the mares subjected to this experiment, the BLM has not sufficiently justified the need for the research when (in their own assessment) all the experiment “may” do is provide “more details” about a surgical procedure. This amounts to first-line experimentation on the very horses that BLM is required to protect from harm and suffering which goes against the agency’s obligations under the 1971 Wild Free-Roaming Horses and Burros Act to protect wild horses from harm and suffering.
The BLM has numerous alternatives for population management of wild horses including PZP (a safe form of birth control which BLM has not widely used).
