不同输精时间对宣凤黄鸡受精率影响的研究
Study on the Inseminate Rate of Xuan Feng Yellow Hen Inseminated at Different Time
【摘要】 本试验采用人工授精技术 ,对母鸡不同输精时间的研究表明 :9:0 0~ 11:0 0输精受精率为 74 3 % ,11:0 0~13 :0 0输精受精率为 78 5 % ,13:0 0~ 15 :0 0输精受精率为 85 0 % ,15 :0 0~ 17:0 0输精受精率为 95 7% ,17:0 0~ 19:0 0输精受精率为 91 6 % ,19:0 0~ 2 1:0 0输精受精率为 89 2 %。试验结果表明 :每天在 15 :0 0~ 17:0 0输精效果最佳 ,早于 15 :0 0与晚于 17:0 0受精率降低 4 1%以上 ,差异显著 (P <0 0 5 )
【Abstract】 The test involved the skill of artificical insemination,The study on the inseminated time to ten manitest:The rate of fecudation is 74.3% inseminated at 9:00~11:00,78 5% at 11:00~13:00,85.0% at 13:00~15:00,95.7% at 15:00~17:00,91.6% at 17:00~19:00 and 89.2% at 19:00~21:00.The result shown that the effect is best if inseminated at 15:00~17:00,and the rat of fecundation lowed over4^1% if inseminated at earlier than 15:00 or late than 17:00
