Perspectives for the use of genomic selection for genetic improvement of dairy cattle in Ukraine

An important problem in modern dairy cattle breeding is the achievement of a high level genetic progress economically traits through implementation effective programs. For this purpose, genomic selection currently used many countries world. The aim study was to investigate possibilities use Ukraine. On basis analysis “Catalogue sires and dual-purpose breeds for reproduction cows 2020” (sperm these Ukraine) two methods value estimation were compared: 1) traditional method based on pedigree performance progeny; 2) effects SNPs. Considerable advantage with evaluations proved. These excel evaluation milk yield by 1.6 times, fat percentage 2.2 1.7 protein 2.1 times times. Using estimates values pare-wise correlations between main computed. negative relationship percentages revealed. Values energy corrected (ECM) daughters dams across origin calculated. It shown that Holstein Jersey had highest (9,132.0 kg 8,041 kg, respectively) while Ukrainian Black-and-White breed lowest trait (5,848.1 kg). According country-of-origin sire’s form USA, Canada Netherlands milk. response using program compared. proved means shortening generation intervals pathways improvement “sires bulls”, cows” “dams bulls” it possible increase rate from 100.1 180.0 80%
