摘　　要：试验选用96只45日龄健康黄羽肉鸡,按照每组体重相近、公母各半的原则分为4组,每组4个重复,每个重复6只鸡,研究棉粕源生物发酵饲料对黄羽肉鸡表观消化率、血液生化指标、免疫指标的影响。Ⅰ组为空白对照组,在基础日粮中加入6%基础发酵底物;试验Ⅱ、Ⅲ、Ⅳ组分别添加6%的热带假丝酵母ZD-3发酵饲料、酿酒酵母发酵饲料、热带假丝酵母和酿酒酵母复合发酵饲料。结果表明:发酵饲料的添加可显著提高干物质、粗蛋白的表观消化率(P<0.05),对粗脂肪的表观消化率影响不大,Ⅱ组钙消化率显著高于Ⅰ组(P<0.05),Ⅲ、Ⅳ组粗灰分、磷的表观消化率显著低于Ⅰ组(P<0.05);与空白对照组相比,试验组血浆白蛋白、钙含量显著增加(P<0.05),总蛋白含量Ⅱ组增加,Ⅲ、Ⅳ组降低,甘油三酯、磷含量降低,血浆总胆固醇含量除Ⅳ组提高外,其余各试验组有所降低;试验组血浆IgG、IgA、IgM含量均有所提高。Ninety six 45-day-age healthy yellow-feather broilers were randomly divided into 4 groups according to similar weight （male：female=1： 1）,and each group had 4 replicates of 6 broilers. This experiment was conducted to study the effects of bio-fermented feed from cottonseed meal on apparent digestibility, plasma biochemical and immune indices in yellow-feather broilers. Group Ⅰ was as control group adding 6% base fermented substrate in basal diet; groups Ⅱ ,Ⅲ and Ⅳ as treat groups were added 6% of Candida tropicalis ZD-3 （CT） fermented feed,Saccharomyces cerevisiae （SC） fermented feed and compound fermented feed of CT and SC,respectively. The results showed as follows： compared with control group,the apparent digestibility of＇ dry matter and crude protein increased significantly （P〈0.05）; whereas,there was no significant difference in digestibility of ether extract among treatment group （P〉0.05）;digestibility of ealcimn ineresaed significantly in group Ⅱ （P〈0.05）and crude ash, phosphorus digestibility in group Ⅲ, Ⅳ were higher significantly than group Ⅰ （P〈0.05）. The albumin and calcium content of plasma in treatment groups were increased （P〈0.05）and total protein content of plasma in group Ⅱ was higher than group Ⅲ and lower than group Ⅳ. Total plasma cholesterol was lower than group Ⅰ but group Ⅳ. Triglycerides,phosphorus were reduced in all groups except group Ⅳ. Treatment groups were improved than control group.
