Effect of combined of Natto powder and monascus powder on growth performance,serum antioxidant index,intestinal flora,and nutrient apparent metabolic rate of Gushi chickens
摘要
Abstract
The aim of the experiment was to investigate the effect of combined use of Natto powder and monascus powder on the growth performance,serum antioxidant index,intestinal flora,and nutrient apparent metabolic rate of Gushi chickens.A total of 200 healthy male Gushi chickens of similar weight at the age of 30 days were selected,randomly divided into five groups with four replicates per group and 10 chickens per replicate.The CK group fed a basic diet,the T1 group supplemented with 1％Natto powder and 1％monascus powder in the basic diet,the T2 group supplemented with 2％Natto powder and 2％monascus powder,the T3 group supplemented with 2％Natto powder and 5％monascus powder,and the T4 group supplemented with 5％Natto powder and 2％monascus powder.The preliminary trial lasted for seven days,and the formal experiment lasted for 50 days.The results showed that compared with the CK group,the average daily weight gain of Gushi chickens in groups T2 to T4 was significantly increased(P＜0.05),the feed to weight ratio of groups T1 to T4 was significantly decreased(P＜0.05).The total antioxidant capacity(T-AOC)and glutathione peroxidase(GSH-Px)activity in the serum of Gushi chickens in groups T,to T4 were significantly increased(P＜0.05),and the content of malondialdehyde(MDA)was significantly decreased(P＜0.05).The number of E.coli in the cecum of Gushi chickens in groups T,to T4 was significantly decreased(P＜0.05),and the number of Lactobacillus was significantly increased(P＜0.05).the number of Bifidobacterium in the cecum of Gushi chickens in groups T2 to T4 was significantly increased(P＜0.05).The metabolic rate of crude protein and crude fat in Gushi chickens in groups T1 to T4 were significantly improved(P＜0.05),the metabolic rate of organic matter in Gushi chickens in groups T2 to T4 was significantly improved(P＜0.05).The study indicates that combined use of Natto powder and monascus powder can improve the growth performance and dietary metabolic rate,improve serum antioxidant indexes,and maintain the intestinal health of Gushi chickens.The combination of 2％Natto powder and 2％monascus powder are better.关键词
