Semen quality of twenty-five ejaculates from twelve boars were investigated. Each ejaculate was equally divided into three treatments: treatment 1, semen was diluted with Kiev diluter at the ratio of 1:3; treatment 2, semen was centrifuged at 2,000 rpm for 10 minutes then half of the supernatant was removed and replaced with Kiev dilluter; and treatment 3, semen was centrifuged at 2,000 rpm for 10 minutes and all of the supernatant was removed and replaced with Kiev diluter. Semen quality of the three treatments were exammined. Sperm motality and percentage of dead spermatozoa of all treatments were not significantly different (P0.05). The amount of normal acrosome of treatment 3 was significantly higher than that of treatment 1 and 2. Thirty-three sows were inseminated with semen of the three treatments. The conception rate and the farrowing rate of treatment 1,2 and 3 were 83.33, 90.00 and 81.20 percent, respectively. In term of pigs born alive, stillbirth and litter weight at birth, the means of treatment 3 was better than the others but the differences were not significant.
