Problem breeding back after lute?

Postby BK9954 » Thu Apr 20, 2017 5:44 pm

Had a heifer 12 months old, 4 months bred. Gave her a shot of lute and she passed the fetus through. Now she is the last heifer not to breed. She has been with my bull since mid December. 2 weeks ago Vet said she might be bred or just a little swollen in heat. Anyone had a problem with a cow not breeding back after using lute or being bred too young? The lute was given in October.

Yes have had some slow breed backs with aborting a too young bred heifer. Usually we will give them 2 shots of lute, one to abort and another to make sure they cleaned afterbirth etc. a bout 2 weeks later. It seems to just throw their systems into a tailspin. They often go anestrus, stop cycling for awhile. I think her body needed more time to readjust to not being pregnant; not anything proven or scientific in my observations. You only gave her 2 months to readjust and then put her with the bull. In some of the dairies, they have more problems with trying to synch heifers than if they had just bred on normal heats. Her nutrition level would also be a factor, but if everyone else is bred it probably is the disruption of her pregnancy and then the body reverting to a non-cycling state.

So reverting to non cycling but probably coming out of that state?

I would say so from just a farmer viewpoint and not any "vet or schooling" knowledge. It just seems that the few we have had to abort take longer to get back to "normal". Someone who has more vet knowledge might know more of the whys and hows. We usually take something we have aborted, and hold them to go to the "next" breeding group.... if we even keep them. Once they have gotten bred and calve they do usually just do fine.

Thanks, she is a fine looking heifer. Hate to sell her at beef price.

Give her a shot of GnRH, that should get things working again

Gonadotropin Releasing Hormone
It causes the cow to ovulate which will clear the dominant follicle. That will restart the heat cycle wave again. It's typically used for cystic ovaries but also works to clear an anestrus situation

Called my vet, been a month since I palpated. Taking her next week to check. He says he has the GRH in his office.

Yeah, we also use Gnrh to get them to cycle and have used it a couple of times when they have been cyctic. Have more trouble in the dairy cross heifers than the beef ones usually.
