Methods and effects of Hongshan cock spermatozoa cryopreservation

  • Liu Jianzhong
  • Zhang Yiling


The survival rates, acrosomic integrity rates of frozen semen from Hongshan cock and fertilities of the frozen-thawed spermatozoa in both pellets and straws were studied. The result shows that the average survival rate of spermatozoa in straws was 0.451±0.056, and 0.390±0.040 in pellets, the former was significantly higher than the later (n=20,p<0.01). The average acrosomic integrity rate of the sperms was 0.613±0.049 in straws, and 0.476±0.057 in pellets. The former was significantly higher than the later (n=20,p<0.05). The fertility rates (%) of sperms in pellets, straws and freshly collected semen, at the third day after artificial insemination (AI) were 85.32±2.32, 87.73±1.00 and 90.77±1.68, respectively. The fertility rates of the three type of semen at the fourth and fifth days were lower than the third day’s. Variance analysis shows that the fertilities of the spermatozoa in pellets and straws were significantly lower than freshly collected semen (n=3,p<0.01), and the fertilities of the spermatozoa in straws were significantly higher than those in pellets (n=3,p<0.01).
