We leave our bull with the herd and let breeding happen when it happens. Most of our cows have calved every 12 or so months with this and we have had no issues. I have one cow, she's 6, she breeds immediately. Her last year calf is just about 9 months and 2 days ago she had another calf. She has done that 4 times in a row. (I took her calf off of her at 5months old so she did have a 4 month break from nursing). She is now all over the bull again today. Its hard for me to separate them at my property but if I leave her she will get pregnant again id assume. Is this ok to do? Does the girl need a break or is it ok to let nature take its course?
