@kenny thomas yes I am in agreement they have been moderating frame for 3 decades now. Enough is enough and they have taken it way too far,
I used to have a Charolais bull that was an 11 frame. That was too extreme, on the other hand 4-5 is too small. I don't care how much a fat 5 frame cow weighs at maturity, Bred to another 5 frame bull that resulting calf is going to have a pretty low growth ceiling.
Selling calves that look the least bit fleshy gets you discounted, forget any so called CAB premium for black calves selling fleshy weaned calves.
Whoever buys them might pick up a premium after grouping up a bunch of yearlings.
In the early 90's I was getting around 750 - 800+ lb weaning weights with purebred Charolais bull calves and over 700 lb for heifers. With Angus sired calves, I'm really happy with 550 almost to the point that I'm thinking wow I can't believe they weighed that good. Years ago that would have been well below the very bottom end cattle growth wise.
With Herefords we've gotten a little bitty bit better weaning weights, but with the Hereford dock it ain't worth it, unless you just really like Herefords. My wife does, so there's that
You have to watch Hereford selection just as close or closer than Angus cause the movers and shakers of the Hereford breed are closely aligned with the show ring and those cattle can be little short fat toads too.
I like at least upper 5 frame up through 7 and would say 8 but probably impossible to find an 8 frame animal these days.
@mwj on the subject of breeding for red from black cows. It can be done just takes a little while. Breed the black cows to a red breed bull. First generation calves would be black but heterozygous. retain those heifers breed to another red breed bull and a good percentage of those calves will be red.
If anybody keeps back heifers each year, you could add a significant number of red replacements within 2-3 generations of breeding for it.
