[QUOTE="DOC HARRIS, post: 1083163, member: 1683"] Invariably, when a question such as this arises in a discussion of beef cattle, the focus almost immediately becomes one pertaining to "Breeds". This is understandable when one considers that producers are concerned with their particular breed, and how those particular breeds have performed for them in the past. But, in my opinon, the primary determining factor(s) for so-called "bad crosses" in mating beef cattle should [i]not[/i] focus on the particular "breeds" involved in the matings, but on the Genetic traits and characteristics of the individuals concerned. Granted, breed "A" crossed on breed "B" will produce progeny reflecting the specific dominate traits relating to Prodction, Maternal, Carcass and multi-trait selection indexes specific for each breed. But where the "Rubber Meets the Road", so to speak, is determined by the concentration and Accuracies of the EPD's and the DNA profiles of each individual cow and bull which produces the progeny! Arguments relating to which breed of cattle is "[i]BEST[/i]" will continue as long as there are cattle breeders talking to one another! But if the discussion ever gets to the point of really being serious insofar as the source of PROFIT and successful matings and crosses in breeding beef cattle, the genetic quality of the cattle and goals of the breeders ultimately will determine the bad crosses and what makes them bad!
