Effects of Honeysuckle Stem and Leaf Powder on Growth Performance,Immune Function,Antioxidant Capacity and Intestinal Health of Ningdu Yellow Chickens
This study aimed to evaluate the effects of honeysuckle stem and leaf powder on growth perform-ance,immune function,antioxidant capacity and intestinal health of Ningdu yellow chickens.Three hundred and sixty 36-day-old Ningdu yellow female chickens with similar initial body weight were randomly distributed into 5 groups with 6 replicates per group and 12 broilers per replicate.They were basal diet group(CON group),the basal diet supplemented with 150 mg/kg chlorotetracycline group(ANT group),and diets sup-plemented with 1％,2％and 3％honeysuckle stem and leaf powder,respectively.The experiment lasted 28 d.The results showed as follows:1)compared with CON and ANT groups,there were no significant differences in body weight at 63 days of age,average daily gain(ADG),average daily feed intake(ADFI)and feed-to-gain ratio(F/G)of Nindu yellow chickens in HO1,HO2 and HO3 groups(P＞0.05).2)The serum diamine oxidase(DAO)content in the HO2 and HO3 groups was significantly lower than that in the CON group(P＜0.05).3)Compared with the CON group,the serum malondialdehyde(MDA)content in the HO1,HO2 and HO3 groups was significantly decreased(P＜0.05),and the serum total superoxide dismutase(T-SOD)activi-ty in the HO1 and HO2 groups was significantly increased(P＜0.05).4)Compared with the CON and ANT groups,the villus height(VH)of the jejunum in the HO1,HO2 and HO3 groups was significantly increased(P＜0.05).Moreover,the ratio of villus height to the crypt depth(VH/CD)of the jejunum in the HO2 and HO3 groups was significantly increased compared with the CON group(P＜0.05).5)Compared with the CON group,the cecal relative abundances of Acidobacteriota and Prevotellaceae_UCG-001 in the ANT,HO1,HO2 and HO3 groups were significantly decreased(P＜0.05),and the relative abundance of Mucispirillum in the HO2 and HO3 groups was significantly increased(P＜0.05).Furthermore,compared with CON and ANT groups,the relative abundance of Desulfobacterota in the HO1,HO2 and HO3 groups and the relative abun-dance of Deferribacterota in the HO2 and HO3 groups were significantly increased(P＜0.05).In conclusion,dietary supplementation with 1％to 3％honeysuckle stem and leaf powder has no significant growth promotion effect,but can improve the antioxidant capacity,immune function,intestinal mucosal morphology and the composition of the cecal bacterial flora of Ningdu yellow chickens,and the appropriate supplemental level is 2％.[Chinese Journal of Animal Nutrition,2024,36(6):3631-3641]
