[QUOTE="Ebenezer, post: 1386035, member: 24565"] Not disagreeing but just mumbling. Lack of fertility culls itself. What we dislike is the time it takes to recognize the "lack of". Weaning weights: Are you sure that is a priority in a linebred herd/line with your stated goals? Ever see the picture of ears from hybrid seed corn parents? Not much to write home about. You and I and others are trying to create an inbred line of seedstock for commercial crosses or for stabilization of traits, especially focused on female function from what you listed as priorities. Weaning weight is not a function of fertility. Milk production is an expense over base need. And if the lower production is occurring in earlier generations, look at the definition of the Bulmer Effect. Early sag and then rebound: country boy interpretation. So showring looks and feedlot performance might have to take a back seat until the animals are crossed out for superior F1s. [/QUOTE]
