Body condition scores were not reported.
Of the horses returned on Day 19, approximately 55% were stallions and all of the mares were treated with PZP. These pest control actions reduce growth rates and keep the resource scales tipped in favor of the public-lands ranchers for longer periods of time, which is what the advocates are trying to accomplish.
