Abstract
The article provides an analysis of the current state of Kustanay breed of horses in the Northern region of Kazakhstan. More than 100 heads of breeding horses of Kustanay breed were recorded and described, incl. 9 breeders, 44 broodmare and 79 heads of young animals of different ages in three regions of Kazakhstan. 60% of the horse population of chestnut, 40% of bay. The height at the shoulder of the broodmares is 156 cm, the oblique body length is 155 cm, the chest girth is 180 cm, the girth of the metacarpus is 19.5 cm. Studhorses are 150-153 180-20.2 cm, respectively. 38% of studhorses are linear - belong to lines 464 Neon and 494 Fort. Average, measurements are somewhat lower than those of horses recorded in the IV volume of the State Book of breeding horses of Kustanay breed (2009), while they correspond to the standard. The probable reason is the evasion of selection and breeding work in the direction of improving the remote characteristics of the massif - orientation to the so-called “baiga” distances. An increase in the index of stretching was revealed against the background of a decrease in flattening and massiveness, with a stable bone index. The se characteristics contribute to ensuring endurance when used at "baiga" distances, which is confirmed by the performance results presented in the article.
