Abstract: This experiment was conducted to investigate the effect of probiotics and chinese herbal compound on oviduct, production performance and egg quality of Hy-Line Brown hens.Seven hundreds and twenty 45-week-old Hy-Line Brown hens with similar body weight and laying rate were divided into 4 groups with 3 replicates in each group and 60 hens per replicate.The hens in control group were fed a basal diet and those in the experimental groups (Ⅰ, Ⅱ, Ⅲ) were fed the basal diets supplemented with 1.5‰ probiotics and 1‰ the Chinese herbal medicine one (patrinia, dandelion, radix, forsythia, etc.), 1.5‰ probiotics and 1‰ the Chinese herbal medicine two (honeysuckle, astragalus, epimedium, motherwort, etc.), 1.5‰ probiotics and 1‰ the Chinese herbal medicine three (folium, treats, skullcap, gardenia, etc.), respectively.The preliminary trial lasted for 7 days, and the experimental period lasted for 28 days.The results showed as follows:① Probiotics-Chinese herbal medicine could repair damaged fallopian tubes, reduce tubal adhesions with the surrounding tissue and keep tubal patency, compared with control group, the contents of TNF-α and EGFR of group Ⅱ were significantly decreased by 40.85% and 17.79%(P<0.05), respectively;② Compared with control group, the laying rate of group Ⅱ was significantly increased (P<0.05), meanwhile the feed/egg and soft-broken egg rate were significantly reduced (P<0.05);③At the end of 48 weeks and 50 weeks, egg shape index and yolk ratio of group Ⅱ were significantly increased compared with control group (P<0.05).Therefore, dietary supplementation of probiotics-Chinese herbal medicine could reduce the oviduct inflammatory reaction of hens in a certain extent, improve the laying rate and egg quality.The better combination was group Ⅱ, including probiotics and honeysuckle, astragalus, epimedium, motherwort, etc.
