The gestation period of a cow lasts around 9 months. After birth the calves are removed from the mother in maximum 3 days. This happens because the mother creates a strong bond with the calf.

After the birth of a calf all cows produce milk. After about 10 months of calving the amount of milk given by the animal naturally decreases significantly and the cow also dries up. About 12 to 14 months after the birth of the previous calf of the cow it will give birth to another calf again and will start giving more milk again.
