摘要
为研究在基础日粮中添加不同剂量酵母膳食纤维对蛋鸡生产性能、蛋品质和免疫球蛋白的影响,本试验选取270只35周龄海兰褐商品蛋鸡分为5个处理组,每个处理组6个重复,每个重复9只鸡,对照组饲喂基础日粮,试验组分别添加1、3、6、12kg/t的酵母膳食纤维,试验周期6周。试验结束后统计蛋鸡生产性能、蛋品质和免疫指标。结果显示:日粮中添加酵母膳食纤维的剂量达到6 kg/t时,能够显著增加蛋鸡的平均采食量,降低鸡蛋的破损率,同时蛋重也有增加的趋势,另外,日粮中添加酵母膳食纤维能够显著增加蛋鸡血清中IgA、IgG和IgM的含量。以上结果表明,日粮中添加酵母膳食纤维6kg/t及以上能够提高蛋鸡的生产性能,改善鸡蛋品质,提高机体免疫力。
In order to study the effects of different doses of yeast dietary fiber on the performance,egg quality and immunoglobulin of laying hens,270 35-week-old Highland brown commercial laying hens were divided into 5 treatment groups with 6 replicates in each group and 9 hens in each replication.the control group was fed with basal diet and the experimental group was fed with yeast dietary fiber of 1,3,6,12 kg/t respectively.At the end of the experiment,the production performance,egg quality and immune index of laying hens were counted.The results showed that when the dosage of yeast dietary fiber reached 6 kg/t,the average feed intake of laying hens was significantly increased,the breakage rate of eggs was decreased,and the egg weight also increased.At the same time,yeast dietary fiber could significantly increase the contents of IgA,IgG and IgM in serum of laying hens.The above results suggested that adding yeast dietary fiber 6 kg/t or more to the diet could improve the production performance,egg quality and immunity of laying hens.
