Oxen consume plants and grains since they are herbivores. Fresh grasses, hay, and grain supplements are all staple foods for domesticated oxen. Wild oxen, like musk-oxen, inhabit the tundra of the Arctic and consume moss, lichens, and roots.
Domestic oxen start working at the age of four. Because steers are more manageable for teamsters to handle than bulls, they are castrated. To get to food, wild musk oxen use their hooves to burrow through the snow.
They have thick, shaggy hair that can withstand cold temperatures. To protect themselves against wolves, they live in groups of two or three dozen.
