The University of Arkansas' Division of Agriculture is warning ranchers in the state about the possibility of acorn poisoning in cattle.
Tom Troxel, the associate head of animal science at the university, says autumn's generous acorn crop may be great for deer but it could be deadly for cattle.
Troxel says cattle frequently graze on pastures that may contain oak timber and there is a chance they will consume acorns. He says an occasional acorn isn't a threat, but too many can lead to acorn poisoning.
Troxel says tannins are the toxic agents found in acorns. He says consuming tannins can lead to gastrointestinal problems, severe kidney damage and even death. Some cattle may consume acorns and experience no ill effects, while others suffer severe disease.
