摘　　要：试验旨在观察棉籽糖对肉仔鸡血液生化指标、生产性能和肠道主要菌群的影响。选用1日龄艾维茵肉仔鸡360只,随机分为6个处理,每个处理6个重复,每个重复10只鸡。试验组在基础日粮中分别添加棉籽低聚糖0.05%、0.1%、0.2%、0.3%和氟哌酸0.01%。结果表明,添加棉籽低聚糖0.1和0.3%可极显著提高21和42日龄肉仔鸡增重(P<0.01)。添加棉籽低聚糖0.3%可显著提高42日龄肉仔鸡甲状腺激素水平和碱性磷酸酶活性(P<0.05),添加棉籽糖的各处理组23日龄甲状腺激素水平和42日龄血清总蛋白水平也有显著提高(P<0.05)。棉籽低聚糖可显著抑制23日龄肉仔鸡盲肠内大肠杆菌的繁殖(P<0.05),0.3%的棉籽低聚糖还可显著抑制沙门氏菌的繁殖(P<0.05)。说明添加棉籽糖可通过改善肠道菌群的繁殖,进而提高肉仔鸡的生产性能和营养代谢水平。Three hundred and sixty avian broilers were randomly divided into 6 groups,with 6 replicates in each group and 10 chicks in each replicate.The basic diet of these 6 groups was similar,and their treatments were respectively additive：raffinose 0.05%,0.1%,0.2%,0.3% and norfloxacin 0.01%.The effect of raffinose on blood biochemical index;growth performance and gut flora in broilers were observed and analyzed.The results showed that the weight gain in 21-day-old and 42-day-old broilers fed with raffinose 0.1% and 0.3%,was significantly higher than that in the control groups（P0.01）.The level of thyroxine（T4） and the activity of alkaline phosphatase in plasma in 42-day-old broilers fed with 0.3% rsffinose were significantly higher than the control groups（P0.05）.The levels of thyroxine（T4） and total protein in blood in 23-day-old and 42-day-old broilers adding 0.05% to 0.3% raffinose,were significantly increased than control groups（P0.05）.The number of E.coli in the caecum in 23-day-old broilers fed with raffinose was significantly lower than the control groups（P0.05）.The number of salmonella population in caecum in broibers fed with raffinose 0.3% was significantly lower than that in the control groups（P0.05）.The results indicated that the bacterium breeding in intestinal in broilers fed with raffinose,were significantly improved.The growth performance and the metabolization function in broilers fed with raffinose,were significantly higher than that in the other groups.
