Abstract
ABSTRACT
This study aimed to study the influences of different extender types on the quality and fertilizing capacity of stallion semen to determine the best extender which may enhances the fertilization capacity of stallion semen. Three healthy stallions aged 4-10 years and sixty mares aged 3-12 years were selected after the breeding soundness examination to accomplish this study. All the animals were with a good general health condition without any history of reproductive failures or disturbances. The external and internal genitalia were examined using the rectal palpation and ultrasonography to avoid any disturbances in the reproductive tract that might affect mares fertility. Semen samples were collected using artificial vagina and evaluated, then diluted by four types of extender and used for mares insemination to determine the influence of extender on quality of semen and conception rate .This study concluded that, the extenders types can influence the fertilizing capacity in mares through its effect on active forward motility of the sperm, dead and live sperm % and the conception rate. The extenders that contain skimmed milk could increase the fertility and conception rates of stallion semen.

Key words: Semen extenders, Semen quality, Fertilizing capacity, Stallion, Mare.
