摘要
[Objective] This paper was to establish a method for quality assessment of Suyou Ⅰ duck. [Method] Semen was collected from 20 healthy drakes using back massage method,to determine semen volume,sperm motility,sperm density,sperm morphology and semen quality factor( SQF) of each individual.[Result]Semen was successfully collected from 15 out of 20 ducks. The results of semen quality assessment showed that the semen volume,sperm density,sperm motility,normal morphology ratio and SQF were( 0. 17 ± 0. 05) mL,( 25. 52 ± 4. 73) × 10~8 sperm/mL,( 0. 86 ± 0. 10),( 86. 93 ± 2. 13) % and( 387. 5 ±129. 25),respectively. The abnormal sperm ratio was( 13. 07 ±2. 13) %,among which the percentages of bent sperm,huge head sperm and damaged sperm were( 7. 70 ± 1. 97) %,( 2. 53 ± 1. 06) % and( 2. 83 ± 0. 79) %,respectively. [Conclusion]Semen quality of Suyou Ⅰ duck is generally high,and could be applied in the production and breeding.
