Tom Troxel, University of Arkansas associate head of animal science, says an over-abundance of acorns this fall and winter could be dangerous for cattle. An occasional acorn isn't a threat, but too many open the door to acorn poisoning from tannins, he says.
"Consumption of tannins can lead to gastrointestinal problems, severe kidney damage and death," he says. "Some cattle may consume acorns and experience no ill effects, while others suffer severe disease."
Many species of oaks are considered toxic to animals. They typically affect cattle and sheep, and they also can occasionally cause toxicity in horses.
