摘要
本试验研究了4种寡糖对健康艾维茵肉仔鸡肠道微生态的影响。选用健康艾维茵肉仔鸡20只,随机分为5个处理,每个处理4个重复,每个重复1只鸡,进行为期40 d的饲养试验。试验第1组为对照组,饲喂基础日粮,第2、3、4、5组为基础日粮中分别添加同一水平糖量(0.015%)的低聚异麦芽糖组(GOS)、低聚木糖组(XOS)、果寡糖组(FOS)、甘露寡糖组(MOS)。饲喂40 d后,研究寡糖对肉仔鸡盲肠微生物(乳酸杆菌、双歧杆菌、大肠杆菌)数量的影响。结果表明,各种低聚糖能显著降低肉仔鸡盲肠微生物中大肠杆菌的数量(P<0.05),其中XOS能显著提高盲肠微生物中双歧杆菌与大肠杆菌的比值,显示出良好的促进双歧杆菌增值的作用;MOS能显著提高盲肠微生物中乳酸杆菌与大肠杆菌的比值,显示出良好的促进乳酸杆菌增值的作用。
This test investigates that different oligosaccharides have different influences on the biology of microbe in the digestive tract of healthy Broiler. In the experiment, a total of twenty healthy AA Broiler were randomly alloted into five treatments with four duplicates per treatment, feeding them for 40 days. Treatment i was control group fed with basal diet, the treat- ment 2, 3, 4, 5 was GOS, XOS, FOS, M0S group respectively, each group had the same amount of sugar level （0.015%）. 40 days later, to investigate the effects of oligosaccharides on the quantity of broilers cecal microorganisms （Lactobacillus, Bifidobacterium, E. eoli）. The results shows that： various oligosaeeharides can significantly reduce the number of E. coli in the cecum of broiler （P〈 0.05）. X0S can significantly improve the ratio of bifidobacillus and colibacillus, showing good ef- fect to promote the proliferation of bifidobacterium. MOS can significantly increase the ratio of lactobacillus and colibacillus, and showing favorable function to accelerate the multiplication of lactobacillus.
