Dee":2co44odo said:I have heard that after 5 months you can "bump" the cow to tell if a calf is in there. I can't even recall if it is the left or right side of the cow you push on. I had a vet show me a couple years ago, and you could feel the calf "bounce back" against your hand after you pushed on the cow. But it's not going to work on a 45 day bred cow.
Bumping isn't infallible either. If it was you wouldn't see supposedly open cows or short breds that calf on the way into the parlor. And it happens more often then you would think.
