In this updated guide, we look at why calves exhibit this behavior toward humans and other animals, the health risks involved, and how modern farmers are managing it. Why is the Calf Sucking on You?
While it might seem harmless to let a calf suck on your hand, there are several reasons why veteran farmers discourage the habit:
Understanding Cross-Sucking: Why Calves Sucking on Farmworkers (and Each Other) Happens
Calves are born with a powerful, instinctive drive to suckle. In a natural setting, a calf would spend a significant portion of its day nursing from its mother. On modern farms, where calves are often separated from the cow and fed via buckets or bottles, this biological "itch" often goes un-scratched.
On a busy dairy farm or a homestead with a few bottle babies, you might find yourself in a strange predicament: a calf that won't stop trying to suck on your fingers, your coveralls, or even your arms. While it might seem like a quirky or even endearing behavior at first, (or sucking on non-biological objects) is a significant behavioral signal in cattle management.
Calves have abrasive tongues and, as they grow, powerful jaws. What starts as a gentle suck can turn into a painful pinch or skin abrasion.
