Instructions
Examine the cow's udder bag. Just before birth, many cows will experience a swelling and tightening of the udders. This may not happen in every circumstance, but it is a good indicator your cow is ready to calve.
Stand behind the cow and take a look at her vulva. Before a cow gives birth, the vulva will begin to sag and will be noticeably bouncing around as the cow walks.
Watch the cow for signs of restlessness or isolation. A cow that separates herself from the herd or continually lies down and stands up again may be close to calving.
Observe the cow for any other signs of distress. Every calving situation is different, and every cow handles it in a unique manner. If you have a pregnant cow that has suddenly started acting weird, it may be best to separate her and prepare for the calving process.
