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. As they grow, calves transition to solid food, such as hay and grain. They are important in agriculture, as they contribute to the production of beef and dairy products. Proper care and nutrition are crucial for their development and overall health.
