In the conditions of the southeastern zone of the Almaty region, under the system of free-range housing without changes in the management technology, the meat and milk productivity of the Kushum breed of horses has been increased at the Bayserke Agro farm through the breeding of highly productive Kushum stallions and mares.The population of Kushum stallions and mares differ from the local Kazakh breed in having better meat forms and higher live weight. In terms of live weight, the Kushum stallions exceed the first-class standard by 42.6 kg (8.52%), while the mares exceed it by 12.5 kg (2.66%).The Kushum horses at the farm are characterized by distinctly pronounced meat forms, tall stature, and a large chest circumference. The body mass index for Kushum stallions is quite high at 136.7, while for mares it is 134.4.During the grazing period, the Kushum breed youngstock, initially in a condition of low-medium fatness after the summer heat, achieved optimal condition. Research has shown that during the first 20 days of autumn grazing, the average daily weight gain of the colts reaches 805-725 g per day. Afterward, by the 40th day of grazing, the average daily gains decrease to 510-260 g, and by the end of the grazing period, on the 60th day, it reaches 80-70 g.When slaughtering young horses after autumn grazing, carcasses with high slaughter yields (53.3-51.6%) were obtained, with a large amount of meat (80.2-82.5%) and relatively low bone content (17.5-19.8%).
