Cows are large, gentle animals that are commonly found on farms. They are known for their big eyes, floppy ears, and distinctive mooing sounds. Cows are raised primarily for their milk and meat, making them an important part of agriculture. They belong to a group of animals called bovines, which also includes buffalo and bison. Cows are social creatures that often live in herds. They have a unique digestive system that allows them to break down tough plant materials, like grass, through a process called rumination. This means they can eat a lot of grass and convert it into energy, which is essential for their growth and milk production.
