As a models of ruminants, syrian hamsters which posses of double stomach and live on alfalfa meal diet, were used. It was investigated absorbancy of VFAs produced by bacterial flora in hamster's digestion tracts.In facts, hamsters were absorbed VFAs from the duct-wall immediately and depend on pH at their cecum. Herbivorous hamsters were more crude protein as well as crude fiber than control groups.On the other hand, it was happened drastic change to bacterial flora in the sacciform part (forestomach, glandular stomach and cecum) contents of hamsters. In control groups fed on cereal diet, intestinal flora was similar to other reports. It was most superior streptococcus in the aerobes, Enterococcus and Bacillus in order to number. It was advanced in turn Lactobacillus, Bifidobacterium, Peptostreptococcus and Bacteroides in the anaerobes.However experimental herbivorous group fed on alfalfa meal diet was simple intestinal flora, Enterococcus, Staphylococcus, Enterobacteriacae in aerobes, Peptostreptococcus and Bacteroides in anerobes were hardly detected. These results could not explain in relation to digestion of crude fiber.

作为反刍动物的模型，使用了双胃并以苜蓿饮食为生的叙利亚仓鼠。研究了仓鼠消化道中细菌菌群产生的VFA的吸收性。在事实上，仓鼠被立即从管道壁中吸收了VFA，并依赖于其盲肠的pH值。草食仓鼠比对照组更粗糙，既是粗蛋白，又是粗纤维。在另一方面，这发生了仓鼠的细菌菌群（Forestomach，腺体胃和盲肠）含量的急剧变化。在以谷物饮食为食的对照组中，肠道菌群与其他报道相似。为了数量，它是动氧，肠球菌和芽孢杆菌中最优质的链球菌。 It was advanced in turn Lactobacillus, Bifidobacterium, Peptostreptococcus and Bacteroides in the anaerobes.However experimental herbivorous group fed on alfalfa meal diet was simple intestinal flora, Enterococcus, Staphylococcus, Enterobacteriacae in aerobes, Peptostreptococcus and Bacteroides in anerobes were hardly检测到。这些结果无法解释与粗纤的消化有关。
