The materials of researches of sexual activity of ram-sires of European meat breeds, in particular: Texel, Oxford Down and Valais Blacknose, in non-breeding and breeding periods are given. It was established that in the non-breeding period, the number of mounts for one ejaculate in the rams of the studied breeds was on average by 34.7-60.2% more and the length of time for receiving it by 67.0-107.7% higher compared to the breeding period according to the rams exploitation schedule to receive 4, 6 and 8 ejaculations per week. However, the index of sexual activity in the non-breeding period was lower on the average by 47.0-51.9% in the Texel breed rams, by 44.9-50.3% in those of the Oxford Down breed and by 40.4-45.5% in the Valais Blacknose breed ones.
It has been experimentally proved that the Oxford Down breed rams, in comparison with the rams of the Texel and Valais Blacknose breeds, showed lower rates in the number of the mounts in order to obtain one ejaculate and in the length of time for receiving it in non-breeding and breeding periods, while their index of sexual activity was higher. This indicates that sexual activity of ram-sires is influenced by both seasonal activity and breed characteristics.
