Re: Genomic Young Sires To Watch
Well stated Buckeye, i'll agree with you all the way here. I think breeding cows is somewhat risk management and genomics over non is probably going to be good while not 100%. Sometimes i question wether genomics would be more reliable as you often see bulls with fairly avg proofs that everyone loves the dtrs etc. Every stud has them. Heres a thought ive pondered. Any bulls you like now that might not have been sampled if they had been genomic tested?

Re: Genomic Young Sires To Watch
There are some sceptics that don't trust genomic proofs yet. I ask them this, have any of you purchased a bull with a bad genomic proof ? He had the pedigree that you like, so you just went ahead and bought him knowing he was chalked full of minuses. Most breeders I know ignore the EBV of a young sire, and buy them on pedigree. Can the same be said when the genomic proof is available?

Genomic Young Sires To Watch
Currently in our herd we are only using genomic proven young sires on hard breeders. I will not use a bull just based on genomic numbers alone, but if I like the pedigree and the genomic numbers are high enough then I will used him more heavily then I normally would. Having said that if a bull has a pedigree I like and his genomic numbers are low then I would not use him at all. A nice benefit of all the genomic young sires is some of the studs are willing to discount some of their higher reliability bulls more than what they had been before genomics.

Re: Genomic Young Sires To Watch
Reliability on a parent average is somewhere between 35-40%. A genomic analysis gives you something like a good guess on a 10 daughter proof ... probably about 65%. A decent progeny test about 85% and a widespread proof at 99%. Once a bull has a decent number of test daughters in a proof then that proof is the most reliable.. dont be fooled by clever marketing and bullmanure

EXACTLY - people want to be fooled, they keep forgetting the relaiability of genomics

Re: Genomic Young Sires To Watch
My apologies, must have been a little drowsy when i wrote that post above and got the name wrong. I think Will is right, well i know Will is right in regard to reliabilities etc. I dont think most studs try to trick you into thinking something else. For me that is why i would use pedigrees and crosses that i like. And if a bull puts it all together all the better. For us i would say we have been burned by using proven bulls that were supposed to be good just as much as using young sires with no information other than pedigree.

Genomic Young Sires To Watch
I would consider it more trickery and BS by hyping a bull and showing PA numbers at 35-40% reliability then showing Genomic numbers at with 65% reliablity.
A 20% spread in the two numbers is HUGE in my opinion.
Like JEB12 already stated. Look for a group of young bulls you like based on pedigree, find the genomic proof that looks the best to your liking and pick that bull.
