“Bumping a Calf” is just what it says – Using a soft fist to nudge the side of a cow’s belly to feel for the shape of a calf inside her around 7-9 months into the gestation.
You can also use a soft rocking motion to see if the calf will “bump” back into your fist.
The purpose of “bumping” is to tell if there is a live calf growing inside the cow, helpful prior to drying off the cow (although, we do recommend also confirming pregnancy through blood or milk testing also!)
Below are pictures and videos explaining the simple, fun project:
