季节和水泥兔舍笼位采光对白色母獭兔受胎率的影响

Effects of Season and Cage Lighting on Conception Rate of White Female Rex Rabbits

为了研究季节和水泥笼位采光对白色母獭兔配怀率的影响,对四川省獭兔原种场不同季节和水泥兔舍笼位白色母獭兔受胎率进行了统计学分析,结果表明:夏季配怀率最高,达88.89%;其次是春季和秋季,分别为83.23%和79.68%,冬季最低,为71.2%,但季节之间差异均不显著(P>0.05);从月份分析可以看出,7月份受胎率最高,为92.31%,12月份受胎率最低,为57.35%,说明光照时间是影响母兔发情的重要因素;全年范围在自然光照条件下,采光较好的靠窗侧受胎率达81.41%,较靠主过道侧受胎率78.07%,提高了3.34个百分点,也再次说明光照对于母獭兔受胎率的重要性。

In order to study the effects of season and cement cage lighting on the pregnancy matingrate of female Rex rabbits, statistical analysis was conducted on the conception rate of female Rex rabbits in Sichuan province Rex rabbit breeding farm in different seasons and in cement cage.The results showed that the pregnancy mating rate was the highest in summer, up to 88.89%.Followed by spring and autumn, 83.23% and 79.68%,respectively.Winter was the lowest(71.2%),but there was no significant difference between seasons(P>0.05);from month analysis, it can be seen that July has the highest conception rate of 92.31%,while December has the lowest conception rate of 57.35%.indicating that light duration was an important factor affecting female estrus.Throughout the year, under natural light conditions, the conception rate of window side with better lighting was 81.41%,which was 3.34 percentage points higher than that of main aisle side 78.07%,which again showed the importance of light on the conception rate of female Rex rabbits.
