registered question

[denoginnizer]

There is a guy down the road that sells registered angus bulls. A friend of mine bought 3 from him last week. He said the guy AI's and then puts a cleanup bull in with them in case the AI didnt work.
The man said the bulls come with papers. How can he know who the sire was to register the bulls?

Hmmm...... And he fessed up to it?

Yes , said not to worry that his clean up bull cost 10000.

So long as there's a bit of a break between the AI and when the bull goes in, it's pretty easy to tell who the sire is. Just check out the service dates adn birth dates, and check the right sire is on the papers. If he's just chucking the bull in straightaway though, then there's a problem. Who knows who the sire is.

Howdy,

Different AI techniques
Some AI and put in with a clean up bull. When the claf is born, a blood test needs to be done to see who the daddy is.
Another method
AI wait 17 days, input a clean up bull to catch the ones that did not take. Simple gestation time of when the calf is born.

not sure on most associations, but im pretty sure some of them.. i know for fact the APA makes all AI sired calves DNA or some how blood typed to find out who the real father is.

The confusion comes in when the calf isn;t born very close to the expected date from the AI. If a calf is born8-9 days after the expected date, is it early or late. For those that we would use a cleanup bull on, we breed them AI to a different breed, that way we know who's the daddy. I realize that doesn;t work with registered herds. Most breeders are unwilling to wait an extra heat cycle or 2, stretches out the calving season too long.

1. Cows cycle every 20-21 days. He may AI them, then wait two weeks to put the bull with them. If they've settled to the AI, they won't breed. If they haven't settled to the AI, they'll re-cycle and the calf should be born later enough to tell which bull he's sired by.

2. Some people DNA test the calves from cows that have been AI bred, then pasture exposed to verify who the sire is..

Ask the breeder that question. He should be happy to explain to you or your friend.

And just because the bull costs 10,000 does not make him worth it.

with ultrasound they can tell alot quicker, i have seen catalogs that say a.i.ed to and then pasture exposed from - until. then it will say safe to ai date. some are only 2weeks until pasture exposed. do they have to DNA test before registering animals?

By the date he AI'd and the date the mother calved.

ultrasound will tell you if they are bred, but with the variation in early size and the fact that you have to wait a 45+ days to ultrasound, i cant see this being a reliable method. DNA obviously works.

Angus association does not require DNA confirmation unless the service date and calving date are pretty far apart (more than 10 days i think). the only time they know the service date/window is on transferred animals.
