Descripción

Efficiency of data transformation strategies is evaluated to correct heterogeneity among cattle in the genetic evaluation of bulls, cows and progenies. Four data structures of bovine weaning weights were simulated: he rds with and without heterogeneity for me ans and variances, and herds with and without genetic connectedness. In the genetic evaluati ons, data were used in the original scale and transformed (Logarithmic, Square root, standardizatio n and ratio by phenotypic standard deviation). The evaluated data transformation strategies were not efficient in eliminating the negative effects of heterogeneity among cattle in the genetic evaluation of bulls, cows and progenies.
