无鱼粉日粮在蛋鸡生产中的应用研究

Application of Diet without Fish Meal on Layers Production

利用酵母和葵花粕代替日粮中的鱼粉组成无鱼粉日粮,以无鱼粉日粮和有鱼粉日粮对蛋鸡进行试验,结果为:饲喂无鱼粉日粮的试验组和饲喂鱼粉日粮对照组的产蛋率分别为67.96%和65.01%,差异不显著(P>0.05);只平均产蛋量为44.73g和42.41g,差异显著(P<0.05);平均蛋重为65.83g和62.29g,差异不显著(P>0.05);死亡率分别为1.69%和2.10%,差异不显著(P>0.05);试验组比对照组每生产1kg蛋饲养成本降低1.9%。因此无鱼粉日粮可代替鱼粉日粮在蛋鸡生产上应用。

Yeast and sunflower cake were used to replace fish meal for the diets, and the diets contained fish meal were reid layers. The results showed that the group which fed fish meal diet had no significant difference （P 〉 0.05） with control in laying rate（67.96% and 65.01%, respectively）, average egg weight （65.83g and 62.28g, respectively）, and death rate （1.69% and 2.10%, respectively）, but the results also indicated that significant difference （P 〈 0.05） occurred in average egg yield （44.73g and 42.41g, respectively）, feed cost of the treatment group reduced 1.9% than that of the control. In conclusion, the diet without fish meal can replace fish meal diet used for laying hens production.
