选择健康新西兰母兔,随机分成3组进行不同补光时间对母兔繁殖性能的影响试验。本次试验结果显示:采取人工授精前3天与前7天补光组(A与B组)的补光制度,两种补光处理结果差异不显著,与激素处理C组相比,均能显著提高母兔同期发情率、发情配种数及怀孕数,受胎率比C组分别高约7.8%与8%;三组母兔群体产活仔率差异不显著。但采取人工授精前3天与前7天补光组(A与B组)的光照制度,能显著提高母兔群体产仔总数。结论:不同补光时间(人工授精前7天与人工授精前3天补光)对母兔繁殖性能的影响差异不显著,综合考虑能耗等因素,实际生产中建议采用人工授精前3天进行补光处理。
Healthy New Zealand female rabbits were selected and randomly divided into 3 groups to test the effects of different fill time on reproductive performance of female rabbits. The results of this trial showed that the two supplemental light treatments did not show any significant difference between the two supplemented light treatments (Group A and Group B) three days before and seven days before artificial insemination, compared with Group C Significantly increased females estrus rate, estrus breeding number and number of pregnancies, pregnancy rate than the C group were about 7.8% and 8%, respectively; three groups of females group live birth rate was not significantly different. However, the illumination system of Fibrillators (Group A and B) on the 3rd day and the 7th day prior to artificial insemination can significantly increase the total number of females in the females group. Conclusion: There is no significant difference in reproductive performance between different supplemental time (7 days prior to artificial insemination and 3 days before artificial insemination). Considering the energy consumption and other factors, it is recommended to use 3 days before artificial insemination Fill light processing.
