ABSTRACT
The article depicts genotype evaluation and selection of black motley bull-improvers of Holstein breed imported from Germany to “Uznaslchilik” state enterprise. According to obtained and analyzed main parameters of bull-improvers, a total merit index of bull genotype (RZG) and official index for production (RZM), conformation traits (RZE), somatic cell score (RZS), fertility (RZN) and farm use (RZR) indexes were estimated and analyzed. These indexes were estimated and selected individually per bull. Estimation and selection procedures on imported bull-improvers are being implemented together with republic breeding farms on breeding herds. These imported productive bulls are obtained from individual ordered selection and pairing of the parental ancestors estimated by generation quality.
