A cow’s gestation period is about nine months long give or take a few weeks depending on the breed. That means a cow is pregnant for about two-thirds of the year. (You can read more about the length of a cow’s pregnancy here.)
During the final three months of pregnancy the cow’s udder will begin to fill with milk in preparation for her calf’s birth. This milk is called colostrum and is full of nutrients and antibodies that will help the calf to fight disease and start to grow.
Just before giving birth the cow’s body will start to produce a hormone called oxytocin. This hormone causes the muscles of the uterus to contract and helps to push the calf out through the birth canal.
The average length of time for a cow to give birth is about two hours though it can vary depending on the size of the calf and the cow herself. After the calf is born the cow will continue to produce oxytocin which will help her to expel the placenta and any remaining fluids.
The cow will then lick her calf clean and nudge it towards her udder so that it can start to nurse. The calf will drink about a gallon of milk per day during its first week of life.
