Calves are young cows, typically less than a year old. They are born after a gestation period of about nine months and are usually nursed by their mothers for several months. Calves are known for their playful behavior and curiosity, often seen frolicking in pastures. They are an essential part of dairy and beef farming, as they grow into adult cows that provide milk or meat. As they grow, calves undergo significant changes, including developing stronger muscles and bones. They start eating solid food, like hay and grain, in addition to milk. Proper care and nutrition are crucial for their health and growth, ensuring they become healthy adult cows.
