What Are Some Calving Signs to Look for in a Cow?

It's helpful to know what to look for when you are eagerly awaiting your cow to give birth. Not all cows react the same way when it comes time to calve, but most have similar symptoms. During a healthy delivery, the cow should be able to deliver on her own, without human intervention. If you are uncertain, contact your local veterinarian for advice and possible assistance.

  1. Two Weeks from Delivery

    • When your cow is two or so weeks away from calving, you will see her udder beginning to fill up. Her vulva will also relax and begin to expand. You may also see the mucous plug begin to dislodge.

    12-24 hours From Delivery

    • The cow's pelvic ligaments will begin to relax and look limp. The cow may also separate from the herd. Cows are social animals, and when they begin to isolate themselves there is a good chance that she is going to deliver soon.

    Less than 12 Hours Away

    • The cow will increase her isolation. You will also begin to notice the cow transition into some discomfort. This will be evident by the switching of her tail and kicking. She also may turn in circles as she tries to get comfortable.

    During Calving

    • When your cow begins to go into active labor, you will see an increase in the signs of discomfort -- including stomping her feet -- and more mucous discharge. As labor progresses she will have increased contractions. The water bag will come out and possibly rupture.
