[QUOTE="DOC HARRIS, post: 400085, member: 1683"] In reading a few of the posts questioning what I wrote - I hasten to say that I was not trying to confuse anyone! Likewise, I was NOT talking against the Longhorn Breed! As a matter of fact, quite the opposite! I was using this thread as an example of some breeders using "One Trait Selection" in the breeding program of ANY breed. Example: Angus Breeder. Looking for a new bull or a new cow. Instead of using the suggested traits of Birth Weight, Calving Ease, Weaning Weight, Yearling Weight, and Milk Production as guide lines for "selecting" a herd bull or brood cows for his herd, he decided to concentrate on ONLY ONE TRAIT - "Calving Ease" - to the EXCLUSION of ALL the other genetic characteristics - generation after generation after generation, keeping heifer calves for replacements. Eventually, the OTHER traits which are important for the development of a successful herd - REGARDLESS - of the breed type - Beef, Dairy, Dual-Purpose, Whatever, will loose their ability to express themselves in the manner which is desirable for success IN THAT BREED! It is my understanding (and if I am off base here I am sure that someone will certainly inform me of it) that there are SOME Longhorn Breeders who are concentrating their breeding efforts toward the development of Horn size, and Hide and Hair Color. Terrific! If that is their goal, they must concentrate their selection choices of seedstock toward the genetics which will produce those traits. That is "Single Trait Selection". It does what it will do. Years ago, some of the Angus Breeders decided to concentrate on Low Birth Weight traits, and High Milk traits. As a result, those strains of Angus Cattle have developed Low Birth Weights and High Milk traits - and have lost muscling traits, particularly in the Hindquarters of a PERCENTAGE of their progeny (offspring). Result: "FUNNEL BUTT" ANGUS CATTLE! LIKE BEGETS LIKE! If you concentrate long enough on the traits that you desire by using seedstock that possess those traits - you will ultimately obtain those traits - good or bad. Holstein breeders have concentrated on HIGH MILK PRODUCTION traits for umpteen years. What do they have? HIGH MILK PRODUCTION! Example of "Single Trait" Selection genetics. DOC HARRIS [/QUOTE]
