Calves are the young offspring of cattle, specifically referring to those that are less than a year old. They are typically born weighing around 60 to 100 pounds and can be either male or female. Calves are known for their playful behavior and are often seen running and jumping in pastures. As they grow, calves are weaned from their mother's milk and begin to eat solid food, primarily grass and other forage. This transition is crucial for their development, as it helps them gain the necessary nutrients to grow into healthy adult cows or bulls. Proper care and nutrition during this stage are essential for their overall health.
