摘    要:选用1 560只1日龄的广西岑溪三黄肉仔鸡,随机分成2组,每组780只,对照组饲喂基础日粮,试验组日粮由基础日粮加0.1%的益生素组成,饲养时间6周,研究多菌种复合菌益生素对三黄鸡的生产性能和肠道主要菌群的影响。试验结果表明:全期试验组的平均日增重比对照组高12.58%(P<0.01),料重比比对照组低9.23%(P<0.05);试验结束时,雏鸡空肠和盲肠大肠杆菌数量分别比对照组低27.61%(P<0.05)和25.57%(P<0.05),乳酸菌数量分别比对照组高16.12%(P>0.05)和11.28%(P>0.05)。

Abstract:The effects of multiplex probiotics on the growth performance and intestinal micro-flora of Sanhuang chicken was studied.A total of 1 560(1-)day old Guangxi Cenxi Sanhuang chickens were randomly assigned into two groups with 780 chicks per treatment.The two dietary treatments were: the basal diet(acted as control) and the basal diet + 0.1% probiotics for the testing period of 6 weeks.The results showed that the addition of probiotics to the basal diet increased the body weight by 12.64%(P<0.01) and decreased the feed with higher ratio by 9.23%(P<0.05)than the control of chicks for 0~6 weeks.The supplement of the probiotics in the diet of chicks also decreased the numbers of Escherichia coli both in the jejunum and cecum by(27.61%)(P<0.05)and 25.57%(P<0.05),but increased the total Lactic acid in the entric by 16.12%(P>0.05) and 11.28%(P>0.05) more than the control,respectively.
Keywords:Probiotics  Sanhuang chicken  Performance  Intestinal microflora
