Abstract
The numbers of total aerobes, total anaerobes, and facultatively aerobic lactobacilli, streptococci, and coliform bacteria were determined in samples of ileal digesta and feces from calves 0, 3, 6, 9, and 12 hr after feeding milk, or milk with sucrose or starch added. Differences in the flora could be attributed to diurnal variation (time from feeding to sampling), source of the sample (ileal versus fecal), nature of the dietary carbohydrate (lactose versus lactose plus sucrose versus lactose plus starch) and age of the animal (on a diet of milk plus sucrose).
摘要
测定了犊牛在喂食牛奶、添加蔗糖的牛奶或添加淀粉的牛奶后0、3、6、9和12小时回肠消化物和粪便样本中的需氧菌总数、厌氧菌总数以及兼性需氧的乳酸菌、链球菌和大肠菌群的数量。菌群差异可归因于昼夜变化（从喂食到采样的时间）、样本来源（回肠与粪便）、膳食碳水化合物的性质（乳糖与乳糖加蔗糖与乳糖加淀粉）以及动物年龄（食用牛奶加蔗糖的日粮）。
