To determine the effect of a certain diet on the intestinal flora of chicks, the cecal flora of chicks fed on a low protein or low lysine diet was examined. The cecal flora of chicks fed on the low protein diet was similar to that of chicks fed on a normal protein diet, but the total count of bacteria, Eubacterium and Enterobacteriaceae in the cecal content of chicks fed on the low lysine diet containing a formulated amino acid mixture minus lysine was significantly lower than that of chicks fed on the control diet. The total count of Lactobacillus in the cecum was remarkably reduced by feeding the amino acid diet, especially the low lysine diet. Levels of most free amino acids in the cecal contents of the low protein group were significantly lower than those of the control. Lysine, leucine, phenylalanine, methionine, histidine, glycine and tyrosine of the cecal contents in the low lysine group were significantly lower than those of the control group.
为了确定某种饮食对雏鸡肠道菌群的影响，对以低蛋白或低赖氨酸饮食喂养的雏鸡盲肠菌群进行了检测。以低蛋白饮食喂养的雏鸡盲肠菌群与以正常蛋白饮食喂养的雏鸡相似，但在含有除赖氨酸外的配方氨基酸混合物的低赖氨酸饮食喂养的雏鸡盲肠内容物中，细菌、真细菌和肠杆菌科的总数显著低于以对照饮食喂养的雏鸡。通过喂食氨基酸饮食，尤其是低赖氨酸饮食，盲肠中乳酸杆菌的总数显著减少。低蛋白组盲肠内容物中大多数游离氨基酸的水平显著低于对照组。低赖氨酸组盲肠内容物中的赖氨酸、亮氨酸、苯丙氨酸、蛋氨酸、组氨酸、甘氨酸和酪氨酸显著低于对照组。
