Comprehensive assessment and selection criteria of replacement heifers for herd creation
Abstract
As a result of researches criteria for selecting replacement heifers for creation of breeding herds owned by RUE «Scientific and Practical Center of the National Academy of Sciences of Belarus on Animal Husbandry» were developed. In accordance with the genealogical structure of maternal stock of the breeding age of SE «ZhodinoAgroPlemElita» plans pf prenatal individual selection were developed. The evaluation and selection of heifers for breeding nucleus is carried out: on the genotype (at birth) - 323 animals, on the integrated index of breeding values at age of 6 months - 246 animals and 12 months of age - 135 animals. Breeding defect material at the age of 6 months made 0,8 %, in the age of 12 months - 0,7 %.
