Abstract: The article is devoted to the study of the state of the reproductive function of Kazakh white-headed meat breed cows in the conditions of Western Kazakhstan in the period 2021-2022 in various farms within the framework of international scientific cooperation between the L.K. Ernst Federal Research Center for Animal Husbandry (Russia) and the Zhangir Khan West Kazakhstan Agrarian Technological University (Republic of Kazakhstan). Obstetric and gynecological examination of 1540 heads was carried out using the rectal examination method and using ultrasound diagnostics with a KAIXIN KX5200 scanner in four farms: Aisulu Farm (300 heads), Dongelek Farm (600 heads), Hafiz Farm (275 heads) and Alem Farm (365 heads). It was found that in all the studied farms during the period of examination, pregnancy with different periods was recorded at the level of 43-45%. Among the non-breeding 862 cows, only 45 ones were sick with various gynecological diseases such as: endometritis, ovarian hypofunction, uterine subinvolution, follicular cyst - which averaged 4.5 - 6.3%, depending on the farm. A treatment protocol (21-day course) was also used, including: follimag, trivit, surfagon, in appropriate dosages and multiplicities. As a result of the experiment, it was found that during the 21-day course all the animals became healthy. Over the entire period of the experiment, using an ultrasound scanner to determine the state of the female reproductive system, the following was carried out: timely identification and treatment of sick animals, constant monitoring of the general condition of animals and preparation of cows for insemination with an optimal choice of hunting time and subsequent insemination. Thus, the average fertility rate on farms was 88.9�0.6 calves per 100 cows in 1540 animals. The best result was noted in the Dongelek farm, where the birth rate reached the level of 95.7 �1.5, and a relatively low result in the Aisulu farm, where the indicator was 82.1�2.4 calves per 100 cows. The service period varied between 46-53 days depending on the farm, with 280-290 days gestation period, the calving intervals was 331-343 days. Due to the integrated approach, the economic efficiency of treatment of cows amounted to 65 thousand tenge for each animal in the Aisulu farm, Dongelek Farm - 39 thousand tenge, Hafiz Farm - 41.7 thousand tenge and Alem Farm - 42 thousand tenge.
