在试验Ⅰ中以含25%和35%不脱正烷酵母饲料(补充0.25%和0.35%DL-蛋氨酸)喂养大白鼠一年。其体重增长显著低于喂养常备饲料的对照组。Vanderwal介绍了一些不同的研究小组以正烷酵母喂养不同的动物,均观察到当酵母用量过高时(15%以上)动物生长即受到抑制,采取各种措施,均未能完全克服。de Groot以含10
Rats were fed for one year in Trial I with 25% and 35% non-norfeed yeast feed supplemented with 0.25% and 0.35% DL-methionine. Its body weight gain was significantly lower than that of the control group fed normal diet. Vanderwal introduced a number of different research groups feeding different animals with n-alkane yeast and observed that when the yeast is used in excess amounts (more than 15%), the growth of animals is inhibited and various measures have not been completely overcome. de Groot to contain 10
