heifers possibly bred to their siblings?

Postby toxxie24 » Fri Aug 25, 2017 10:33 pm

I recently found a group of heifers that have been pastured with their bull siblings. they range from 12 to 18 months. i am sure that some , if not all, may be bred. they are out of pretty good stock and look really good: the price is also right. i considered buying them and treating them with lutelyse, then breeding them all together later. also, considered having them preg checked and only using lutelyse with the ones that were way too young. just wanting some opinions.the sire was simangus. the mommas were angus cross cows.

If they are not very far along, I would lute all them, give them a couple of months to get their " ïnsides" all back to normal and then breed them so that they calve when i wanted the calves. But since some are 18 months you say, if they have some decent size and growth, then you could keep them bred and get a few calves. The thing is, if they don't have some good growth, then you are asking them to do a job that their systems might not be ready to do.
Actually with the age spread, I would probably be splitting them into 2 groups, so that ones of similiar size and age are calving together. I also would not keep any of the resulting calves due to the inbred of siblings.

It really depends on their age, condition, and if you are set up to deal with some heifers that could have potential problems.

Preg check the large ones. Keep the ones large enough pg and lute all the too small without bothering to preg check.
Sell resulting calves from the the ones you keep pg as weaned calves. Too close of inbreeding stunts their feed lot
performance, so I would not want to feed them out myself.

That is very concerning given that some were 17 & 18 months old.
Get them on a good mineral program asap.

If the sire is "proven" (lots of progeny) "in-breeding" could actually be "line-breeding". The "brothers" are 1/2 the sire & the heifers are 1/2 the sire, so the offspring is only 1/2 the genes of the grand-sire.
I would be extremely concerned that they are NOT all pregnant.

Can you check where you bought these heifers to see if the rancher is having trouble with his other cattle?

If there were bulls in the pasture with your heifers, then they should have all been bred.

The offspring could be all of the grand sire or none of the grand sire. Most likely somewhere in between, only DNA testing can say where.
