Decanamine hydrochloride (a C10 primary amine), N-methylundecanamine (a C11 secondary amine) and N, N-dimethyldodecanamine (a C12 tertiary amine) were tested for their effects upon in vitro cellulose digestibility by unadapted ruminal microorganisms. The three amines exhibited similar patterns of inhibition of cellulose digestibility in 48-hr in vitro incubations. Cellulose digestion was depressed to 97, 89, 31, 11 and 12% of the control value by 5, 10, 25, 50 and 100 ppm of the amines, respectively. Total volatile fatty acid production was depressed to 89, 85, 61, 40 and 32% of the control value by 5, 10, 25, 50 and 100 ppm of the amines, respectively. Propionate production was inhibited to a greater extent than was acetate production, and acetate to propionate ratios increased in the presence of the amines. The results demonstrate that these primary, secondary and tertiary amines inhibit those microorganisms which digest cellulose in the rumen.
对盐酸癸胺（一种 C10 伯胺）、N-甲基十一胺（一种 C11 仲胺）和 N, N-二甲基十二胺（一种 C12 叔胺）进行了测试，以研究它们对未经适应的瘤胃微生物体外纤维素消化率的影响。在 48 小时的体外培养中，这三种胺对纤维素消化率的抑制模式相似。胺浓度分别为 5、10、25、50 和 100 ppm 时，纤维素消化率分别降至对照值的 97%、89%、31%、11%和 12%。胺浓度分别为 5、10、25、50 和 100 ppm 时，总挥发性脂肪酸产量分别降至对照值的 89%、85%、61%、40%和 32%。丙酸盐的产生比乙酸盐的产生受到更大程度的抑制，并且在胺存在的情况下乙酸盐与丙酸盐的比率增加。结果表明，这些伯胺、仲胺和叔胺会抑制瘤胃中消化纤维素的微生物。
