How To Know When A Cow Is Calving?
How do you know when a cow is about to calf? Rectal palpation is the cheapest and most convenient method of pregnancy testing cattle.

How long after a cow bags up will she calve? Some cows and heifers have so much udder development that you think calving is imminent, but they go many more days before the actual event.
