Having calves weaned early is often something that occurs during periods of low forage quality. This typically happens during extremely dry periods, such as what is currently happening in many western states. But what exactly does it mean to wean early?
Early weaning is usually defined as weaning calves before they are 150 days of age. In some more extreme cases, they can be weaned even earlier at 45 days. This rarely happens so more commonly early-weaned calves are over 80 days old.
As I mentioned earlier early weaning can be of benefit to producers facing a drought. It can also be useful when cows are in a confinement system. Also as a body condition management tool for old and young cows.
It is a useful tool because once you take the calf off of the cow her nutritional demands go down. Once she no longer has the demands of lactation she can be maintained on poor quality forages with little to no supplement needed.
