The term for a young cow is "calf." Calves are typically born weighing between 50 to 100 pounds, depending on the breed. They are nurtured by their mothers for several months before being weaned and transitioning to solid food. During this early stage of life, calves require a balanced diet primarily consisting of milk to support their rapid growth and development. Once weaned, their diet shifts to grass, hay, and other feed that fulfill their nutritional needs. In agricultural practices, the proper care and management of calves are crucial for successful cattle farming.
