Rams are herbivores. They typically eat seeds, grass and plants. Their diet changes depending on the season, though. In the summer, they eat grasses or sedges and in the winter, bighorns eat woody plants, such as sage, willow and rabbit brush, according to Defenders of Wildlife. What they eat also depends on the type of bighorn. For example, desert bighorns eat plants found in their location, such as desert holly and desert cactus.
One swallow of food isn’t enough for these animals. They will regurgitate their food into their mouths. This regurgitated food is called cud. Then, they will rechew the food and swallow it once again. This is part of their digestion process.
