I agree with 3way regarding Milk EPD's.
I am a 'die-hard' conservative when it comes to mixing Milk traits in conjunction with Growth and Carcass traits and characteristics. By attempting to come up with a "magic potion" which combines Growth traits, Carcass traits AND Maternal (MILK) traits into perfectly-performing BEEF MACHINES we run into genetic problems in regard to heritability traits - which are antagonistic to each other, and which result in skewed expectations. For example - it has been found that certain correlated physical-type changes usually occur when intense selection for femininity (Milk EPD's) are stressed in matings resulting in cows that lack muscle and capacity ("Funnel Butts" and shallow bodies (Dairy type, if you will). Also - LONG TERM selection for low birth weight may decrease muscling and increase calving difficulty for replacement heifers due to reduced pelvic area. The important factors here are to realize that the operative phrases are "Long Term" and "Intense Selection" over time.
The above results and genetic "ricochetting" of specific traits and characteristics just intensify the importance of stressing "BALANCE" with EPD's and "Functional" traits, and the intelligent use of all of the stockmanship factors in beef cattle breeding.
I received an email recently from a CT reader (NOT a contributor) who sarcastically criticized me for always "yapping" about EPD's and "Balancing" basic traits. My answer to him was "You DAM right I do"!
Hoover Dam is a bull that more than adequately "balances" MOST EPD's and traits - with MY exception of his MILK trait. It is too high! By the same token, one must be diligent in "Balancing" common horse sense with selection processes when one animal has 18 or 20 traits and characteristics that are optimal, and perhaps one or two which are not so desirable. THAT'S where common sense should prevail, and extremes must be avoided. An EPD of +30 (Hoover Dam for example) should not determine that his use in AI should be thrown out with the bath water! By balancing the +30 with the lesser Milk EPD's of the cows to whom he is mated can result with replacement heifers possessing more desirable Milk EPD's - - so long as their OTHER traits are in BALANCE with his! I call it the "Teeter-Totter Effect" of practical mating protocols. Moderation with each breeding decision will result in gradual but SUCCESSFUL Profits. I prefer to see Milk EPD's not over +25 - in almost ALL cases.
I would use Hoover Dam in a "Ft. Worth" Minute if I have the females to balance with him! His accuracies are excellent! . . . and if I didn't have the females, I would use him on those who were as close to him as possible and then find another bull to balance with his heifers for genetic improvement. THEN - breed those replacements BACK to Hoover Dam!! The possibilities of improvement make the butterflies in my stomach flutter!
