夏季产蛋鸡日粮中添加动物脂肪对提高产蛋性能的效果

Effects of Adding Animal Fat into Layer Diets in Summer on Laying Performance

夏季 ,产蛋鸡日粮中添喂动物脂肪的试验组 ,与不添喂的对照组 ,两组产蛋率分别为 85 .7%和 79.2 % ,两组差异显著 (P <0 .0 5 ) ;平均蛋重分别为 6 2 .44± 1.13g和 6 2 .2 7± 1.32g ,两组差异不显著 (P >0 .0 5 ) ;料蛋比两组分别为 2 .5 1∶1和 2 .6 8∶1,两组差异显著 (P <0 .0 5 ) ;经济效益试验组比对照组提高 9.6 %。

In summer, the laying rate of the layers in treatment group fed on the diets with animal fat and that of the control group without animal fat were 85.7% and 79.2% respectively. The difference between the two groups was remarkable( P < 0.05 ), and the average egg weight 62.44±1.13 g and 62.27±1.32 g respectively, no remarkable difference( P >0.05). The ratio of egg to feeding were 2.51∶1 and 2.68∶1 respectively, with significant differences( P <0.05). The economic benefit of the treatment group increased by a factor of 9.6% comparing with the control group.
