I do understand that the average producer in the beef industry is doing the opposite of all other protein producing competitors and it is not good for the beef industry or producer profits.
So you are proposing more separation between maternal and terminal lines?
I have forgotten the multiplier, but fertility is __ times more economically important than growth. I found it:
Cow herd reproductive potential is 10 times more important than calf growth traits and 20 times more important than calf carcass traits to herd profitability because without reproduction and a live birth calves aren't produced and don't grow.

So where is the main huff and puff in beef production and marketing?
If you are a purebred breeder you are taught to leer at AI bulls and drool over bulls and cows of given herd prefixes. A high priced ancestor or a show winner really makes a cow luscious and a bull extra tempting. Then if the "right people" are using something linked, Oh WOW! No animal has to have high accuracy just be a fad which is often a passing fad. Just buy the semen, use it and if it fails then you can be comforted to know that a lot of other progressive folks tried and failed with you. But some particular extreme EPD is important so that you can be a breed leader.
Commercial breeders have been schooled for decades that "pounds is where it is at". If you want to be really progressive you seek the best of carcass traits to add to the pounds with a blind eye to convenience traits such as udders, feet and legs. And the "best bull" is always the biggest one. Thus bull test stations cull the bottom and sell only the big boys and the "best". There is nothing better than a performance tested bull that has proven his worth .... or so they say.
What is the average bull in a bull test station? It is a bull sired by a bull that is known for terminal traits from a cow family with above average growth and carcass traits to keep the entered bulls from being in the bottom cut or having bad performance and measurements. So, the generation types stack like this: terminal, terminal, terminal, terminal, ...
I admire folks who see the problem. Some see it as a way to raise and promote duckbutt type cattle as protest types and to sell them they have to ignore sale barn prices and build hype on "efficiency" of the cow. Good enough but if we go broke being efficient and raising cattle that will only work in a minority nitch market then the majority of breeders of the "little boys" will go broke trying to be anti-standard breeders. Raising cattle in the right way is not a protest march against the establishment but should be for the good and income of the grower and his farm or ranch.
Cow herd reproductive potential is 10 times more important than calf growth traits and 20 times more important than calf carcass traits to herd profitability because without reproduction and a live birth calves aren't produced and don't grow.
So, does this 20X or 10X seem to favor terminal or maternal? I will assume that if you or I go to the places where we sell cattle and ask they can tell us a frame size that the order buyers want. So we can learn an appropriate sized animal for maximum returns. Then we make a personal decision: would I rather have $10 than $1 or maybe even $20 rather than $1?
We have established a frame size, a motivator and now we need highly fertile cattle. HP in Angus tell us about the initial breeding of a heifer but no more. Pathfinder tells us a bit about fertility but not fully about production. The weaning ratio on the calves of a pathfinder have to be above 100%. That is fine if the breeder is culling the bottom end enough to keep all weaning weights tight. But there are monkeys at the zoo. And, anyway, weaning weights have nothing to do with my extra $9 or $19. Somebody tell me about stability in other breeds- is it accurate and based on whole herd reporting?
Bottom line: we are doing the same things over and over again and losing protein market share and are not maxing out farm income. So after a rambling rant of the deranged: do we need to focus on maternal lines and means to select for the best of maternal lines?
