GROWTH AND DEVELOPMENT OF YOUNG HORSES OF KAZAKH BREED LIKE JABE AND THEIR CROSSBREEDS IN HERD HORSE BREEDING

Abstract

This article presents the results of a study of the features of growth and development of young kazakh breeds of the jabe (KJ) type  and new altai-kazakh crossbreeds of the I-generation (NA x KJ) in the conditions of year-round pasture-breeding in the north-eastern part of Kazakhstan. According to the results of the study, it was found that crossbred foals (NA x KJ) are born slightly larger. So, the live body weight of 3-day-old male foals averaged 46.5 kg, and in  female foals 44.7 kg, which, in comparison with foals of the same age as the kazakh breed of the jabe type, the superiority is, respectively, in male foals by 2.3 kg, and in female foals by 1.3 kg. The existing superiority of crossbred foals (NA x KJ) is observed throughout the entire study period. A similar trend is observed for changes in the linear dimensions of the body of animals. So, at the age of 6 months, on average, the superiority of linear sizes in crossbred foals (NA x KJ) was: at the height of the withers by 1.9-1.1 cm; along the oblique length of the trunk by 8.0-7.9 cm; along the chest circumference by 4.8-4.3 cm and along the pastern circumference by 2.2-2.1 cm.
