METHOD FOR SELECTING BULL SIRES FOR MOTHER HERDS OF VARIOUS PRODUCTIVITIES

摘要

FIELD: husbandry. SUBSTANCE: method resides in selecting bull sires for using or not using them in specific herd. During selection, method uses index parameter indicative of surpassing genetic index so as to achieve optimum "genotype-medium" interaction. Introduction of index parameter makes it possible to perfect cattle breeds without interfering with capacity of biological system for self-reproduction and self-development under specific feeding conditions and preserving genetic stability of animals. EFFECT: higher efficiency. 1 tbl
