Have you ever stood out in the middle of a pasture looking at a cow and saying to yourself: “She’s as big as a house. I know she’s going to calve soon, but when?” The $64,000 question. Of course, I can always go up to my girl friends and pop the question: “When are you due?” But, unless you talk bovine, you won’t be able to do that. Likewise, unless you know the exact date that the cow conceived, it’s always a guess. Well, I found an article that can help you with that when will she calve question. It is not an exact science, but it should get you pretty close. Of course, you can always have your vet give you their best estimate, but that will cost you $$. And in this day and age, $$ is usually short coming.
