Abstract:The purpose of the study was to determine the milk productivity and chemical composition of the milk of mares of the Kazakh breed of the jabe type (KJ) and the Novoaltay-Kazakh crossbreeds of the 1st generation (NA x KJ) in the conditions of herd keeping. To determine the milk productivity of mares, 2 experimental groups were formed with a total of 30 mares, 15 individuals were selected in each group. The studied animals were formed according to the principle of pairs of analogues in the context of full-age gr… Show more
“…A special importance is emphasized on developing productive horse breeding (Zhaleluly et al, 2019;Iskhan, 2020;Kargaeva et al, 2022;Kargayeva, 2020;Baimukanov et al, 2023;Baymukanov and Aubakirov, 2023;Assanbayev et al, 2019;Sharapatov et al, 2023;Kargaeyeva et al, 2023).…”
Research works on the improvement of mare pregnancy diagnostics and evaluation of biological activity of gonadotropic preparation based on the use of enzyme-linked immunosorbent assay were carried out. As the result of diagnostics and evaluation, effective producers as donors for obtaining gonadotropic preparation among the Kazakh population of mares with type "zhabe", the animal units of 60 days with their 5-6 year pregnancy containing FSH -10,380,65 mIU/1 mL and 7-8-year-old with FSH content -10,500,32 mIU/1 mL; 70 days of their 3-4-year-old pregnancy with FSH content -10,520,21 mIU/1 mL, 5-6-year-old with FSH content -11,340,45 mIU/1mL, 7-8-year-old with FSH content -11,340,32 mIU/1 mL, 9-10-year-old with FSH content -11,060,29 mIU/1 mL are identified. A new method for the selection of a drug by biological activity based on the content of follicle-stimulating hormone level for a given herd was developed, which allows to determination of the activity in international units, without the traditional, labor-consuming, outdated method for determination using laboratory white mice, addressing ethical issues in research.
