Evaluation of the breeding value of sires by genome analysis

Abstract

The successful introduction of genomic selection into production was a decisive technological leap for the effective implementation of breeding programs around the world. The number of registered populations, the optimization of scientific methods, the use of information technologies, as well as the testing of the animal genome at once by a large number of markers make it possible to achieve more significant genetic progress in the breeds; it is not jellied to select animals by traditional methods. Methods The article reflects the results of a genomic evaluation of the breeding value of 14 repair bulls, obtained by targeted custom mating. Results According to the results of the analysis, it was established that the scope of the total genomic assessment of the calves' value of gobies (GTPI) was from 1276 to 2049, and the average goby index was 1566 with 71% accuracy. The highest breeding value index for milk yield was for two bulls (GPTA = +371 and +721) and two for fat content in milk (+0.16 and +0.15). Conducted organizational and research work has allowed to develop a conceptual scheme for the early selection of high-value genotypes with subsequent seed production (12-14 months) as from bulls-improvers.
