满江红作为家禽益生元的可行性研究

The study no feasibility of Man jiang-hong used as prebiotics of poultry

用分别添加0.5%、1%与10%满江红的配合饲料喂1日龄AA肉鸡,21日龄、42日龄的体重0.5%、1%添加组显著高于10%添加组和对照组(P<0.05)。0.5%、1%添加组鸡只粪便的双歧杆菌和乳酸菌的总数较对照组增多60%,而大肠杆菌数量则下降67%。不同浓度的满江红溶液,添加于培养基中,进行体外增菌和抑菌试验,满江红对双歧杆菌体外增殖和大肠杆菌体外抑制均有良好的效果。以上结果表明,满江红可以作为家禽益生元。

The feedstuffAA chicken of 1 day oldwith 0.5%, 1% and 10% Man Jiang-hong were fed respectively into the The body weights of the chicken fed the feedstuff with 0.5% or 1% Man Jiang-hong at 21 or 42 days old were higher significantly than that of the chicken fed the feedstuff with 0% or 10% Man Jiang-hong （P〈0.05）. The total number of bifidobacterium and lactobacillus in dejecta of the chicken fed the feedstuff with 0.5% or 1% Man Jiang-hong increased about 60% while the E.coli decreased about 67%. The in-vitro experiments were carried out and the results indicated that Man Jiang-hong had better effects on proliferation of bifidobacterium and on inhibition of E.coli. All the results above indicate that Man Jiang-hong can be used as prebiotics of chicken.
