Many predators and scavengers will eat beef if given the opportunity. That said, not many predators actively hunt and kill cows and bulls due to their size. In desperate situations, wolves and coyotes can take down a cow and eat it. Dead cows and bulls will be scavenged by raccoons, bears, crows, vultures, and anything left to rot will be consumed by flies/maggots, other insects and microorganisms. This list is far from exhaustive, but numerous species eat cow meat besides humans.
