Abstract. One of the most important and promising areas of domestic productive horse breeding today is herd meat. It is most sustainable and has a positive trend of development, due to the low-cost technology of keeping, breeding and growing, compared with other sectors of grazing. An analysis of the pedigree structure of herds in the Altai Republic showed that the main role in the herd horse breeding of the region is given to horses of the Novoaltaiskaya breed of meat direction of productivity, the basis of which, like any other factory breed, are brood mares. It is well known and repeatedly confirmed by studies that the hereditary and phenotypic properties of the mother have a great impact on the quality of the offspring of any lineage. The aim of the study was to determine the severity of the uterine composition of Novoaltaiskaya breed of horses of economically useful traits and to identify the most promising and valuable breed lineages in the Altai Republic. Methods. The lineage ratios in the broodstock of horses of Novoaltaiskaya breed in the farms of the region as of 2018 are analyzed. The characteristics of the uterus of various lineages by age and quantity are given. A linear analysis of the indicators of the main economically useful features is carried out. The results of the study showed the superiority of the uterus of the Rekrut and Mech lineages in the main breeding traits – live weight, basic measurements and assessment of conformation. Based on the results of the study, the further direction of breeding work to improve the horses of Novoaltaiskaya breed in the Altai Republic was determined. The scientific novelty of the study is a comparative analysis of the current state of the lineages of the Novoaltaiskaya breed of horses in the context of the broodstock of the Altai Republic.
Keywords: Novoaltaiskaya breed of horses, brood mare, broodstock, lineage, genealogical structure, economically useful traits, live weight, conformation, measurements.
