- W2029453058 abstract "Abstract Herd-year-season effects are not individually adjustable and yet contribute nearly 50% of the total variation in production. Herdmate comparison method was designed to adjust records for this major source of environmental differences without knowledge of individual influences. Essentially, in evaluating sires the sire of a daughter group is the genetic unit, and daughter averages are regressed on their adjusted herdmate averages. In cow evaluation, however, the genetic unit is a cow; therefore, an intracow regression of her performance on her adjusted herdmate averages is pertinent. Intracow regression coefficient (b c ) is difficult to estimate, since only those cows making records in more than one herd contribute anything to the estimation. Estimates for intrasire regression coefficient (b s ) are available. The relationship between b c and b s is b c = 2b s −1 which provides a consistent estimator for b c with the bias factor being simply the inverse of the sample size for estimating b s . The value .9 is commonly used for bs in the sire proofs. The value for b c in cow index procedure for the similar purpose is then .8." @default.
