I use my own bulls as clean ups after A.I. But they are from proven sires and my best cows.
I won't use anymore of the young bulls in the catalogues as their numbers will almost be garanteed to change drastically.
I used to scan for carcass epds, submit all the weights etc. but wasn't getting paid for it.
I had some pretty smart business people tell me I was 15 years ahead of my time, believe me that's not as fun as it sounds.
Anyway I have gone back to just having the bulls in a pen with a bw and the buyers have to look at them. No other data unless they want pedigree.
It's been a lot more fun and I have been selling more bulls.
