I know from watching the open cattle in the field that approx. 3 days after they are in heat a bloody discharge is usually present on the tail when there is no bull to breed the cattle. But if there is a bull in the field, he breeds the cow, and she takes, can that blood still be there at 3 days or so? Or is that an indication that she is still open? A friend ask me the other day and I couldn't answer it with 100% confidence. I've seen it on my open cows but never really paid attention to the ones with the bulls.
Thanks
