Warning: this is hard to watch. Undercover investigators have filmed a video exposing neglect at a U.S. livestock auction house in New Mexico, according to a story in the Daily Mail. The footage was shot by activists at Animals' Angels after they heard a number of complaints from residents nearby. The video showed four animals who were near death, one of them with a huge hip wound. Owner Dennis Chavez is said to be a "kill buyer" who trade livestock primarily for slaughter, and the group said he shipped more than 10,000 horses to be killed last year.
