Save Wild Horses from Deadly Experimental Sterilization Surgeries

The BLM is planning painful and potentially life-threatening medical experiments on wild protected mares in The Warm Springs Herd Management Area.

They want to start the trauma by rounding them up helicopters, by chasing them with helicopters which often results in injuries or death in itself. They will then surgically sterilize the Mares using an experimental and inhumane procedure. The Mares undergo ovariectomies through a colpotomy — an invasive and risky surgery whereby the mare's ovaries are pulled out while the animal remains conscious.

This is painful and there is no aftercare so intestines can pop out of the site and infection is a huge risk. The mares who are pregnant will miscarry and many mares will die. They want to use mares who are in different stages of pregnancy.  They have now had the horses so long they have given birth but in now way changes the fact this is inhumane. 

This proposal is especially unconscionable considering a humane method of population control is available through the use of the proven PZP birth control, which is used with many animals and has a proven success record.

Please join me asking the BLM to not abuse the animals they are supposed to be caring for.

"U.S. District Court Judge today issued a preliminary injunction to stop the (BLM) from proceeding with controversial experiments to surgically remove the ovaries of wild mares in Oregon. The experiments were set to begin this month on mares rounded up from the Warm Springs HMA ." It will be challenged but it gives us time to get this blocked permantly. I will keep this going and will take it in to BLM and to Others. There are also other lawsuits pending So hope this is over soon!!

It has been deemed cruel and inhumane and led to the withdrawal of two prominent universities from participating in this shameful act.--
