Answer:
CALVES CANNOT GET BRED. A calf is a young bovine that has not reached maturity, and is not weaned or has just been weaned from her mother. A calf becomes a heifer after she has been weaned (or is no longer dependent on her dam), and that heifer will be bred when she is 15 months of age. By the time she is of that age, she is no longer a calf.
