How much does a bison eat in a day?
A full-grown bison can eat anywhere from 25 to 50 pounds (11 to 23 kg) of vegetation in a day, depending on factors such as their size, age, and the availability of food. During the winter, when food is scarce, bison may reduce their intake to conserve energy. In the summer, when food is abundant, bison may consume up to 5% of their body weight in vegetation each day. It's important to note that bison are herbivores and primarily graze on grasses, but they may also browse on shrubs and other woody plants when available.
