Soapweed -Moderation in all things" is a pretty good motto to live by. Even in bull buying, I don't even necessarily want "the best" bulls that a seedstock producer has available. The "best" bulls usually become the biggest.
In our (yours and mine) discussions of EPD's in the past, you KNOW how my fingernails 'scratched' the blackboard when I read the above quote of yours! :lol2: :cry2:
I won't engage in a dialogue relating to EPD's, but I would like to ascertain that we are reading from the same blackboard in regard to our moot interpretations of the "best" bulls, and that we have unanimity of thought concerning the "culling" of the bottom half of our cowherd.
Let's address the "culling" issue first, for that can be resolved more quickly than the "best" item on the docket. Figures don't change, so we all know that if we cull 50% of our cow herd one season, 50% of the cow herd remains. Naturally, if we cull 50% of THAT remaining herd only 25% remains. But in the process of culling the original 50%, we are obligated to introduce replacement breeder's (either heifers or producing cows) in order to maintain the numerical size of the original herd. By virtue of improving the Genetic and Phenotypic traits and characteristics of the Replacement females, we incrementally make quality progress exponentially with each culling session. The more frequently we "cull and replace with higher quality females (and, understandably using the "BEST" bulls available) the more quickly we will approach optimal perfection in our breeding programs. Considering a herd of 100 breeding females, after 5 cullings of the bottom half of the herd, only 3.125 females are left remaining of the original herd - assuming the replacements are an improvement over the quality of the foundation herd. Now we are the proud owners of 100 very high quality females - all other variables being equal, and ruthless culling has been employed in the process.
Now, let's flip the blackboard over and concern ourselves with the issue of the ". . .best bulls usually becoming the biggest". I can agree with that premise, - IF - one is selecting the bulls on size only and ignoring other traits and characteristics, such as Functional, Maternal, Carcass Values, and $Values - paying PARTICULARLY CLOSE ATTENTION to the Balancing of Genetics and Phenotype to avoid the inevitable problems resulting from "run-away" size exacerbations.
I embrace the maxim or doctrine of "Moderation In All Things" providing that ALL things are taken into consideration in the determination of selecting "useful, uniform, moderate sized cattle" which will work well for all involved participants.
An in-depth discussion incorporating the CORRECT usages of EPD's and Phenotypical selection would involve reams of paper and many-sided blackboards to even approach unanimity of thought between people of like temperment!
