Be On The Lookout: Storms can lead to acorn poisoning in livestock
A head’s up for cattle producers with trees on their pastures. Acorns can be deadly for livestock.
They contain very high levels of tannins, which can damage the lining of the digestive system, and lead to ulcers.
Once broken down, tannins release other toxins that can severely damage kidneys and blood vessels. A livestock veterinarian says he most often sees acorn poisoning after storms when trees are blown down and acorns spread on the ground, making them easy for cattle to eat.
