Removal of seminal plasma by centrifugation (0 centrifugation, 1 centrifugation, 2 centrifugations, 3 centrifugations) and preservation in two different tris-extenders viz., avocado seed milk (ASM) and soy bean milk (SBM) based extenders were studied for their ability to support motility, in vitro capacitation and acrosome reaction of spermatozoa obtained from West African Dwarf (WAD) goat bucks during cryopreservation. Semen samples collected with the aid of artificial vagina were centrifuged for one, two and three times. The centrifuged samples were diluted with the two tris-extenders each containing 20 mL of avocado seed milk and soybean milk and cryopreserved for 30 days. The results showed higher (P < 0.05) sperm motility (P < 0.05) with increased centrifugation times. Spermatozoa that were centrifuged had higher (P < 0.05) percentage of acrosome reaction and capacitation with increased centrifugation times compared to the control. Optimal improvement in these parameters was obtained with increased centrifugation times. The findings revealed that removal of seminal plasma by centrifugation improved sperm quality of WAD goat bucks during cryopreservation and optimum improvement was achieved consistently with 3 centrifugations.
