This experiment was carried out to investigate the effect of bovine serum ablumin (BSA), sugars, glycerol equilibration time, straw size and thawing method on the survival index and the morphology of frozen boar spermatozoa. The results obtained were summarized as follow: 1. When the semen frozen in BF5 dilutor as pellet form was thawed in BTS at 37$^{\circ}$and 50$^{\circ}C$, BF5 dilutor with fructose showed higher sperm survival index than that with dextrose, however, when the semen was thawed on dry test tube at 37$^{\circ}C$, BF5 dilutor with sucrose showed higher sperm survival index than with other sugars. 2 When the semen forzen in BF5 dilutor with straw and thawed at 37$^{\circ}C$, BF5 dilutor with dextrose showed higher sperm survival index than those with other sugars, and there was no difference in sperm survival index between 0.5 and 1.0 ml straws. 3. The sperm survival index of frozen sperm was significantly (P<0.05) improved due to addition of BSA (0.05%) to BF5 dilutor. 4. When the extended semen with BF5 dilutor contatining 0.01 to 0.05% of BSA was frozen in the straw, the semen without glycerol equilibration showed significantly (P<0.05) higher sperm survival index than those with 2, 4 and 6 hrs glycerol equilibration time. 5. The sperm frozen in BF5 dilutor with dextrose or fructose, sucrose and raffinose showed 77 to 88% in normal acrosome rate and no difference among sugars. 6. The frozen semen showed lower normal acrosome rate than the first and second diluted semen, whereas the frozen semen showed higher swollen, damaged and missing acrosome rate than the first and second diluted semen. 7. Damaged and missing acrosome rate of sperm head due to freezing was somewhat inhibited by addition of BSA (0.01 to 0.05) to the BF5 dilutor.
