If you set up your herd to concentrate on maternal traits you have to do two things in my opinion. No. 1 is you have to cull ruthlessly. If Lisa Janes show heifer doesn't breed back every you sell her. If her heifer has a bad udder you dump them. If they have a bad disposition you dump them. Its almost more about eliminating the bad ones then selecting for good ones. I don't know if people still index cattle like they used to but if you concentrate on udders,milk,pelvic region, moderate birth weights, disposition, and weaning weights you have more than enough on the plate to concentrate on. The problem is in small herds that Lisa janes show heifer never gets culled cause she cost 5,000$ or whar ever. Good or bad or right or wrong that is the truth. Stayability is boring and you don't win ribbons for it but it is the no. 1 profit determining factor in a maternal situation. The ave purebred herd length is what 6 years. Its the length of a family 4-h herd length of lasting. If you look at someone lke Keith Lauers herd. Hell he's 100 years old(just kidding). He has making these common sense selections for decades. There has been all this selection going on there for years. All it takes is commitment and time and disipline. It just seems crazy people in maternal breeds pushing big yearling epds. You can't select for every trait out there. Its immpossible. You can't be everything to everbody. You have to set paramiters and hopes to concentrate on 3 or 4 traits then spend 10 years working this over. Select and cull both.
