【摘要】 定量测定了雏鸡,中鸡和成鸡的11个正常肠道菌群,结果①随日龄增长双歧杆菌和大肠杆菌显著增加,肠球菌显著减少;②不同肠段作T测验比较,除需氧芽胞杆菌无显著差异外其余均有显著差异(P<0.01);③在空肠和直肠占优势的菌群为双歧杆菌、乳酸杆菌及拟杆菌。更多还原

【Abstract】 This study determined Lactobacillus and ten bacterial group from jejunum and rectum in the healthy chicks. The result shows as follows: As the day-aged increases, enterococci reduce apparently but E. coli and bifidbacilli increase ob viously. The bacterial number in jejunum compared with that in rectum on the T test, marks a significant difference existing in 8 bacteria ( P<0.01 ), except aerobiescens bacillus.更多还原
