The extenders and the cryoprotectant contents of frozen semen pellets were studied using the plate in boar. The results showed that the number 7 was the best extender (p<0.05)in seven groups, and the best cryoprotectant was glycerol (p<0.01).When the glycerol content was 2 percent (p<0.05),the sperm motility of frozen semen pellets was best in all treatment groups.The method of dry thawn of frozen semen pellets was better than that of wet thawn(p<0.05); the sperm motility was 0.46-0.49 after the frozen semen pellet was thawed at 40to 45 ℃. supplyment in the extender could increase the thawn sperm survival time and motility effectively(p<0.01).
