海口地区蛋鸡高密度叠层笼养工艺饲养效果的实验研究

Feeding Effect Study on Confined High Density Stacked Cage Laying Houses in Haikou

结合高密度蛋鸡叠层笼养工艺在海口地区的实际应用，对实验舍蛋鸡的产蛋率、死淘率等生产性能指标进行了研究。结果表明：产蛋率接近于标准生产性能，但蛋重明显减小，次蛋率＜０．４％，料蛋比≤２．３∶１，死淘率＜１０％，总体生产性能指标优良。

In the view of the practical application of stacked cage rearing laying hen technology in Haikou, some performance tests had been made in a stacked cage laying house such as laying rate, death rate and so on. It was drawn that laying rate is almost equal to the standard value , the weight of per egg lower than the standard value, the broken egg rate less than 0 4%, feed egg rate less than 2 3∶1 and death rate less than 10%. The whole performance is very well.
