birth control for heifers

Is there birth control for heifers? I have 2 heifers that I want to put in the general population and not be bred by the bull.

Yes. It's called Noasatal. Either that or they'll have to keep their legs crossed.

LPH, Simple....It is called "Abstinence" Put the bull in another pasture. It is practiced all the time here in Texas.

I have used MGA when the girls were going to be close to the bull with out good fence tween them. Don't know of anyting to use with'm in general population. If you have a large animal vet or some one who AI's close by ask them. I know there is alot of ways to syinc cows for AI, don't know if there is an implant that keeps'm for cycle'n with something like progesterone or not.

I'd say the cheapest way would to keep a good HOT wire tween them and the bull.

Good luck.

Do you wish to keep them intact and breed them later?

In my experience, it takes a whole lot more than an electric fence to keep a bull from doing what his instincts tell him he is supposed to do.

On our ranch when I was a kid, we kept the bull or bulls locked up when we had heifers in the herd population that we didn't want bred just then, usually because they were too young. Our bull pen was a corral made of railroad tie posts set 3 feet in the ground with 2x6 rails set close together with the top rails about 6 feet off the ground. The gates were welded steel made of heavy pipe. The bulls were not pleased at being locked up and tried to get out, but never succeeded. It is interesting seeing a large Hereford bull standing on its hind legs trying to climb over a tall fence.

If the heifers are small enough, and the bulls are large enough, the heifers will not be capable of holding up the weight when they are mounted, and the bull will not be able to "make contact". However this can be pretty hard on the heifers, since the bull will keep trying.

These days there might be something that you could treat the heifers with to prevent pregnancy temporarily. I would suggest talking to a good large animal vet. I would hope that the technique would cause the heifers to not come into heat, rather than something that would prevent fertilized egg implantation, since the former would cause the bull to more or less leave that heifer alone.

Interesting question. We often had a pretty noisy place when the bulls were locked up, because they sure didn't like it and bellowed challenges a whole bunch. But it was the ONLY effective way to be sure that our bull would not impregnate the heifers during their first heat period. If you find out about a drug treatment technique that will work, please post the results. Good luck!

There is a drug you can get from the vet that will cause the cow to abort her fetus. I've had to use it a few times over the years when I've had a fence "failure". It would not be a preventive tho and I'am not sure how far along the cow can be bred for it to work.

Separate the bull from the herd.Don't fiddle with nature.

If your bull won't stay put behind 5 strands of HT you don't have it hot enough. I have never seen testostrone push a bull over a fence that tested over 5.0 kV.
