摘  要：
试验旨在研究2种主要水溶性茶籽提取物茶籽多糖和茶皂素对良凤花肉鸡生产性能和肠道微生物菌群的影响。试验选用1日龄健康良凤花肉鸡800羽,随机分为4组,每组4个重复。抗生素组饲喂基础日粮添加5mg/kg恩拉霉素,试验组Ⅰ、Ⅱ、Ⅲ分别在基础日粮中添加茶籽多糖300mg/kg、茶皂素500mg/kg和茶籽多糖300mg/kg+茶皂素500mg/kg。结果表明:肉鸡日粮中添加水溶性茶籽提取物,在试验第3阶段试验Ⅰ、Ⅲ组平均日采食量显著高于抗生素组和试验Ⅱ组(P<0.05);日粮添加茶籽多糖和茶皂素均有利于肉鸡盲肠中乳酸杆菌的增殖(P<0.05),添加茶皂素能够降低盲肠大肠杆菌的数量(P>0.05)。

摘  要：
Effects of water-soluble extracts from Camellia oleifera seed on performance and intestinal microflora of Guangxi local broilers were studied in this trial.A total of 800 one-day healthy broilers were randomly assigned to 4 groups,control,test group Ⅰ,Ⅱ and Ⅲ,with 4 replicates of 50 birds each group.The experimental time was 51 days,which was divided into 3 phases(1～20 day,21～39 day and 40～51 day).The control group were added 5 mg/kg Enramycin in the basal diet,while test group Ⅰ,Ⅱ and Ⅲ were fed with basal diets supplemented with 300 mg/kg Camellia oleifera polysaccharides,500 mg/kg Camellia oleifera saponin,300 mg/kg Camellia oleifera polysaccharides and 300 mg/kg Camellia oleifera saponin,respectively.The results showed that the average daily gain and feed conversion rate of broilers in all test groups were similar to those of control group(P > 0.05),the average daily feed intake of test groupⅠand Ⅱ were higher significantly than that of control and test group Ⅲ during 40～51 day(P < 0.05).Dietary supplementation of Camellia oleifera seed extracts decreased the sum of E.Coli in cecum(P > 0.05) and showed positive effect on the colonization of Lactic bacteria(P < 0.05).The results suggested that water-soluble extracts from Camellia oleifera seed can promote the growth performance and optimize the microbial ecosystem of intestine.
