We all need animals that fit our environment. That is the hard and expensive part of the learning curve in animal breeding. This sounds stupid at first: mere culling is not breeding selection of livestock. Merely culling every year does not yield better results until you learn how to select proper breeders for your area, forages and management. Otherwise you cull the same problems every year.
Just because a bull grows well, has the right pedigree or any other positives or sale lines does not make him a great breeder. Study your environment and see what overall type, size and thickness any native cattle or ruminant wildlife have and begin to see if you want that or are willing to pay more in quality pastures and feed to keep something different. I still think that we ruin ourselves by not judging bulls for libido rather than the main emphasis for carcass and growth.
I agree that there are many, many components to culling criteria, not least of which is the breed in general and animal in particular being the right fit to the ranches' environment.
Where I disagree with you, unless I'm not understanding you, is that culling poor breeders is always the right culling decision. As I mentioned, no one management decision can have a more detrimental affect on a herd more quickly than allowing poor breeders to stay in the herd, propagating their undesirable reproductive traits.
Open cows drain cash flow and are the most expensive animal a rancher can own. It is the managers responsibility to remove them from the equation at the earliest opportunity.
