摘要
为探明甘露寡糖对‘三黄鸡’免疫功能和盲肠菌群的影响及替代抗生素的可行性,选用1日龄‘三黄鸡’216只,随机分为6组,每组3个重复,每重复12只鸡,分别饲喂6种不同日粮,自由采食和饮水,第Ⅰ1g组/k为g甘空露白寡对糖照、组2,g第/kgⅡ甘、露Ⅲ寡、Ⅳ糖、、Ⅴ4、gⅥ/k组g甘为露试寡验糖组和,在8基g/k础g日甘粮露的寡基糖础。上结分果别表添明加:(61)00添m加g/4kgg林/kg可甘霉露素寡、糖,可显著提高胸腺指数(P<0.05),有提高脾脏和法氏囊指数的趋势,但差异不显著(P>0.05);(2)饲料中添加600mg/kg林可霉素或4g/kg甘露寡糖,均能显著提高血清溶菌酶活性(P<0.05),而8g/kg甘露寡糖组血清新城疫抗体滴度均显著高于对照组和林可霉素组(P<0.05);(3)添加甘露寡糖,可显著提高盲肠乳酸杆菌的数量,降低沙门氏菌的数量(P<0.05),大肠杆菌的数量有增加的趋势但差异不明显(P>0.05));(4)甘露寡糖可替代林可霉素在‘三黄鸡’养殖中的应用。
To study the effects of konjac mannose-oligosaccharides in diet on the immunity function and mecum microflora of‘three-yellow broilers’and the possibilitity of substitutes for antibiotics, two hundred sixteen one-day‘three-yellow broilers’were divided randomly into 6 treatments with three replicates. There were twelve broilers per replicate with feed and water provided ad libitum. The basic diet of the six groups was the same and treatments are as follows： control （no MOS and no lincomycin）, 600 mg/kg lincomycin, 1 g/kg MOS, 2 g/kg MOS, 4 g/kg MOS and 8 g/kg MOS. The results showed： （1） 4 g/kg MOS level of the diet significantly improves the index of thymus （P 0.05）, and had a tendency of increasing the index of spleen and bursa but not significantly（P 0.05）. （2） 600 mg/kg lincomycin and 4 g/kg MOS of the diet both increased serum lysozyme level significantly（P 0.05）, however, 8 g/kg MOS of the diet had the higher serum antibody titres to new castle disease virus than the control group and lincomycin group （P 0.05）. （3） Compared to the control group, MOS significantly increased the concentration of lactobacillus and decreased the number of salmonellae （P 0.05）, in addition the number of E. coli had a higher tendency but not significantly（P 0.05）. （4） MOS could substitute for the lincomycin in the‘three-yellow broilers’feeding.
