Genotype x season x method interaction in evaluating dairy sires from progeny records



Genotype x season x method interaction in evaluating dairy sires from progeny records



Can. J. Anim. Sci 49(2): 151-55



Correlations between transmitting-ability estimates made from records on daughters of the same sires in different seasons are presented. The estimates were made from specifications for different contemporary comparison and herd mate methods applied to the same total amount of data. The lowest correlations were those with the contemporary comparison procedure and no age correction. Age correction did not significantly increase the correlations when only 1st lactations were used.
