The potential of milk productivity of Kazakh Bactrians in the Balkhash zone

Abstract

Camel breeding in the Republic of Kazakhstan is an eff ective branch of herd animal husbandry in the harsh climatic conditions of deserts and semi-deserts. The purpose of the research was to determine the potential of dairy productivity of camels of Kazakh Bactrian in the Balkhash zone. The object of research was camels of Kazakh Bactrian breed in the Balkhash zone of Kazakhstan. The research was carried out in 2021–2022 on the basis of the camel farm of LLP “ESPC Bayserke-Agro” to ensure an optimal level of feeding and breeding work. The research was carried out in accordance with the methodology of experimental work adopted in livestock science. Dams of Kazakh Bactrian camels signifi cantly exceeded their daughters by 214 kg or 24,0 % (P ≥ 0,999) in milk yield for 210 days of lactation. In terms of the mass fraction of fat in milk, dams were inferior to their daughters by 0,2 abs.%, and the yield of milk fat in dams was higher by 9,2 kg or 19,5 % (P ≥ 0,999). In dams the mass fraction of protein in milk was signifi cantly lower in comparison with daughters by 0,3 abs.% (P ≥ 0,999), at the same time the yield of milk protein was higher by 5,3 kg or 14,9 % (P ≥ 0,999). According to the results of the research a high percentage of the implementation of the parent index of camels in terms of their milk productivity during the fi rst lactation was established, which ranged from 92,8 to 103,9 %. Monitoring of the average daily milk yield in uterine livestock showed that over 3 months of observations it tended to increase. The selection and genetic parameters of productivity ensuring the progress of breeding of Kazakh Bactrian camels of the South Kazakhstan type in the Balkhash zone of Kazakhstan were considered.

Reference Values of Blood Biochemical Parameters for the Zhabe Type Kazakh Horse in the Southern Region of the Republic of Kazakhstan

“…[4]. Thus, previous research on zhabe horses has focused on conservation of breed, characterization of genetic diversity, and study of meat productivity along with morphological and biochemical parameters [5][6]. Studies of blood in herd horse breeding, in scientific and practical terms, are given due attention, since by studying its composition one can most deeply understand the features of the interior of animals and the biological essence of the ongoing processes.…”
