Seasonal variation in seminal characteristics of West African dwarf sheep in the humid tropics.
Semen collected from six mature West African Dwarf (WAD) rams by artificial Vagina, twice weekly for one year, early and late rainy season, and early and late dry season, showed no significant difference in volume of ejaculate and progressive motility of sperm. There was significant difference in sperm concentration, total sperm per ejaculate, total motile sperm per ejaculate and abnormal sperm. Seasonal changes in characteristics of the semen were associated with seasonal changes in temperature, indicating the detrimental effects of heat, even on indigenous stock.
