downer cow
A downer cow is a live cow that cannot walk. This state can be caused by disease or injury. In nearly all cases it is considered by most farmers to be both humane and cost-effective to slaughter the animal when it becomes a downer, rather than keeping it alive and unhealthy. A "splitter" cow is a live beef or dairy animal that the hindquarters have done the complete splits and looks spraddle legged upon initial viewing. The cattle that go down that are able to still sit somewhat up on their briskets have a better chance of recovery than the cattle that are laid out on their side. Recovery is a study in patience
