| 摘 要： | 试验旨在研究复合微生态制剂和开口抗生素对肉雏鸡免疫性能、肠道菌群和血清生化指标的影响。选取180只1日龄健康雌性白羽肉雏鸡,随机分为3组,每组3个重复,每个重复20只。Ⅰ组为对照组,饲喂不含抗生素的基础日粮;Ⅱ组为复合微生态制剂组,在基础日粮中添加2.0‰复合微生态制剂产品;Ⅲ组为开口抗生素组,在基础日粮中添加莫能霉素(90 g/t)、抗敌素(30 g/t)和阿散酸(100 g/t)。试验期14 d。结果表明:①14日龄时,试验Ⅱ组法氏囊指数和脾脏指数分别显著高于对照组和试验Ⅲ组(P<0.05);②7日龄时,试验Ⅱ组盲肠大肠杆菌数显著低于对照组(P<0.05),14日龄时,试验Ⅱ组小肠乳酸菌数显著高于试验Ⅲ组(P<0.05);③14日龄时,试验Ⅲ组肉雏鸡血清白介素2含量显著低于试验Ⅱ组和对照组(P<0.05),谷丙转氨酶含量显著高于试验Ⅱ组(P<0.05),但与对照组相比差异不显著(P>0.05),且14日龄时,试验Ⅱ组尿素氮含量显著低于试验Ⅲ组(P<0.05)。提示,在基础日粮中添加2.0‰复合微生态制剂能部分或全部替代开口抗生素应用在肉雏鸡生产中。

| Abstract: | This experiment was conducted to investigate the effect of compound probiotics and opening antibiotics on the immune function,intestinal microflora and serum biochemical index of broilers.180 one-day-old female broilers with similar body weight were randomly divided into 3 groups with 3 replicates in each group and 20 chickens per replicate. The chickens in control group (group Ⅰ)were only fed with a basal diet,group Ⅱ was the compound probiotics group,supplemented with 2.0‰ compound probiotics, group Ⅲ was the antibiotics group by adding monensin (90 g/t),colistin (30 g/t) and arsanilic acid (100 g/t). The experiment lasted for 14 days. The results showed as follows: ①At the age of 14 days,the spleen index and the bursa of Fabricius index in group Ⅱ were all significantly higher than those in control group and group Ⅲ(P<0.05). ②At the age of 7 days,the number of cecal E.coli in group Ⅱ was significantly lower than that in control group(P<0.05). At the age of 14 days, the number of intestinal lactic acid bacteria in group Ⅱ was significantly higher than that in group Ⅲ(P<0.05). ③At the age of 14 days, the content of interleukin 2 in serum in group Ⅲ was significantly lower than those in group Ⅱ and control group(P<0.05), the content of glutamic-pyruvic transaminase was significantly higher than that in group Ⅱ(P<0.05);and at the same age,the urea nitrogen content in group Ⅱ was significantly lower than that in group Ⅲ(P<0.05). In conclusion,the supplementation of 2.0‰ compound probiotics could partially or completely replace opening antibiotics in broilers production. |
