牛科, or the family Bovidae, includes a variety of hoofed mammals known as bovids. This family encompasses animals such as cattle, sheep, goats, and antelope. Bovids are characterized by their even-toed hooves and typically have horns, which can be found in both males and females in some species. Bovids are primarily herbivorous, feeding on grasses and other vegetation. They are found in diverse habitats around the world, from grasslands to forests. Their social structures can vary, with some species living in large herds while others are more solitary. This adaptability has allowed them to thrive in various environments.
