Most form pairs during the breeding season, but in some species, such as fur seals, the gray seal (Halichoerus grypus), and elephant seals, males (bulls) take possession of harems of cows and drive rival bulls away from their territory.
Look for the crooked tail. This is probably the best ways to tell if a cow has been bred: A cow or heifer will have a crooked tail or a tail that is held out in an odd angle than usual for 24 to 48 hours after being serviced by the bull. 1  4 Edit step.
Cows will produce milk for as long as a producer (dairy or beef) needs to have them produce milk, whether it's a time frame of around 6 to 10 months or longer, depending on th â¦ eir type and class of the cows and the producer's management criteria. The time frame, on average, is between or either 6 to 10 months. Give your doe at least 8wks before you breed her again, but that really is pushing it. The best idea is to wait 3months before you breed her again, so she can regain s â¦ ome condition. Keep in mind that does can come back into heat 1 month after kidding (mostly mini breeds). Do not breed her at this time.
