The research is focused on the duration of the genesial cycle in adult ewes (from 4to 6 year old) of Chui, Chingiz, Degeress, Edilbai and Kazakh fine-wool breeds.





The interbreed variability and inbreeding variability of genesial cycles in ewes were established. The duration of genesial cycles of ewes within the breed varied widely from 13 to 21 days. For example, genesial reproductive cycle in 42.9% of Chui breed reached 13,14 and 15 days, in 57.1% - 16 and 17 days respectively. Chingiz and Degeress ewes had genesial cycle of 16 and 17 days. Whereas 66.7% of Edilbay and Kazakh fine-wool sheep the duration of genesial reproductive cycle reached 15 and 16 day, in 33.3% of sheep was measured from 21 to 18 days respectively.

Keywords: sheep, estrous cycle, reeding season, embryos.
