Резюме: An investigation was carried out for establishing the effect of use of non-hormonal methods for stimulation and estrus synchronization in 423 sheep from the Caucasian breed in different body condition. The influence of static, dynamic, and acute effect was studied by using various schemes of additional feeding and
the ram stimulation effect. It was established that under optimal breeding condition (BCS = 3.47) the best results were obtained by using ram stimulation and applying acute additional feeding. Dynamic feeding for a period of 35 days is suitable for ewes having BCS - 3.20.
