Quick Answer. According to Animals Australia, the natural lifespan of a dairy cow is approximately 20 years. The average lifespan of a beef cow is 15 to 20 months.
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.
