Abstract:

This experiment was conducted to investigate the effect of Chinese herbal-probiotics-bile acids compound on production performance,egg quality and immune indexes of laying hens.160 495-day-old Hy-Line Brown hens in healthy were chosen and divided into 2 groups with 4 replicates per group and 20 hens per replicate.The hens in control group were fed a basal diet and that in the experimental group were fed the basal diets supplemented with 0.2% Chinese herbal-probiotics-bile acids compound (Astragalus,Angelica ainensis,Lactobacillus,bile acids,etc).The preliminary trial lasted for 1 week,and the experimental period lasted for 3 weeks.The results showed that the laying rate, average egg weight and average daily feed intake of the experimental group were increased by 4.97%,1.71% and 0.49% than that of the control group and feed/egg of the experimental group was decreased by 6.33% than that of the control group.The experimental group of protein height,yolk color and Haugh units were higher than the control group by 9.87%,6.64% and 3.94%.The IgA and IgG of experimental group were increased by 2.38% and 1.51% than that of the control group,respectively.The quantities of Lactobacillus in feces of the experimental group were significantly higher than that in the control group (P < 0.05),while the E.coli in the experimental group were significantly lower (P < 0.05).In conclusion,the addition of Chinese herbal-probiotics-bile acid compound preparation for the laying hens could improve the production performance and egg quality,and have a certain effect in improving immunity and disease resistance.

Key words: Chinese herbal-probiotics-bile acid compound; laying hens; production performance; egg quality; immune indexes
