Jinglebob, why feedlot test a bull whose intended use is to produce range cows? Wouldn't it make more sense to forage test?
Randy, I agree with what you have said. The way a cow and bull consistently reproduce themselves in their progeny is through homozygous genetics. Out crossing and cross breeding shuffles the genetic deck...heterozygous genetics, which give the benefit of heterosis and covering flawed genetics, but with more variability in progeny. Closed herd linebreeding moves the herd toward homozygosity...whether it is good or bad depends on the good old patient rancher who follows his eye...correctly! Before genome mapping, the single gene/single trait theory said us high forms of life had well over 100,000 gene pairs. Turns out, we don't have many more than the average earth worm!!!!
