This studies were conducted to investigate the survival rate of frozen-thawed spermatozoa of Jindo Dog by monosaccharide and freezing rates. Experimental animals were prepared 12 males within 1~8 year's old and collected once in a couple of weeks by digital manuplation methods. Collected semen was diluted 1:1 with Tris-egg yolk extender and added 4, 6 or 8% of glycerol and none, 4 mM glucose or 4 mM fructose as cryoprotectant and was equilibrated for 2 hrs in . In monosaccharide groups, the freezing rate was 5 cm-5 min. above . The survival rates without monosaccharide were , , in 4, 6 or 8% glycerol, respectively. In addition of glucose, the survival rates were , , in 4, 6 or 8% glycerol, respectively and in fructose, were , , in 4, 6 or 8% glycerol, respectively. There showed significantly different between glycerol groups and monosaccharides groups (p<0.05). The survival rates of freezing rate in 5 cm-5 min. group was , , and in 10 cm-10 min. group was , , in 4, 6 or 8% glycerol, respectively. There were significantly different between freezing rates (p<0.05). These results suggest that the addition of fructose with 6%-glycerol and slow freezing improve the survival of frozen-thawed sperm in Jindo Dog.
