Summary:In order to prolong semen preservation and improve pregnancy rate, semen freezing was studied with German shepherd dogs for experimental animals. The semen of four dogs was collected 40 times in four dilution frozen into two formulations, according to the sperm motility to compare the advantages and disadvantages. The result indicated that the sperm motility of the pellet frozen semen in dilute 2 was significantly higher than that in dilution 1, 3, and 4 （P0.01）. The sperm motility of dogs semen with fried smoked method was notablely higher than that of frozen semen of program method （P0.01）. The dilution which contained yolk-Tris mainly was the best; the pellet semen frozen with fried smoked method was superior to tuble semen frozen with program freezing method; sperm motility of pellet semen was higher than that of tuble semen in the same dilution. The conception rate and litter size of the natural matting were higher than AI.
