| 摘 要： | 本试验对分段光照和连续光照条件下蛋用型北京油鸡的生产性能、采食时长、产蛋时间进行了研究。结果表明分段光照对蛋鸡的开产日龄没有明显影响,对产蛋前期产蛋率、耗料量的影响差异显著(P<0.05),对平均蛋重的影响差异显著(P<0.05),对料蛋比的影响差异极显著(P<0.01);对产蛋中期产蛋率、蛋重、耗料量、料蛋比影响均差异极显著(P<0.01);不同光照制度下蛋鸡的采食高峰时间和采食时长不同,产蛋高峰均集中在上午时段。分段光照和开灯时间早的试验组,蛋用型北京油鸡产蛋中前期的生产性能较好。

| Abstract: | This experiment was conducted to compare production performance,frequency of feeding and laying time of egg-type Beijing You chicken during segmental photoperiod and continuous photoperiod.The results showed that photoperiods had no significant effect on age of the first egg.At previous laying stage,the effect on laying-rate,average daily feed intake and average egg weight was significant(P <0.05).The effect on feed conversion rate was extremely significant(P<0.01).At middle laying stage,the effect on layin... |
