A calf is a young bovine animal, specifically a young cow or bull, that is typically less than one year old. Calves are born after a gestation period of about nine months and are usually able to stand and walk shortly after birth. They primarily consume their mother's milk, which provides essential nutrients for growth and development. As they grow, calves gradually transition to solid food, such as hay and grain. Proper care and nutrition are crucial during this stage, as it sets the foundation for their health and productivity as adult cattle. Calves are often raised for various purposes, including dairy production and beef farming.
