Data comprising 4,959 lactations of 2,414 Brown-Swiss cows, daughters of 70 sires, from 51 herds, were used to estimate the variance component for sire x herd interaction on milk and fat yields and to verify the effect of this interaction on sire genetic evaluation, using the models that differed in the presence or not of the interaction term. The milk and fat yields were adjusted for two milkings, 305 days of lactation and age cow. Likelihood ratio test was used […]
