(Chris Detrick | Tribune file photo) Wild horses from Utah’s Swasey herd are rounded up by Cattoor Livestock Roundup Co. in the West Desert, Feb. 14, 2013. In this operation, the Bureau of Land Management administered a fertility vaccine to most of the gathered mares and returned them to the range. Now the Trump administration plans to turn to surgical sterilization after abandoning fertility vaccines, starting with Utah’s Confusion herd later this month.
