Steers fitted with simple rumen and abomasal cannulas were given isoenergetic diets of rolled barley and chopped straw, pelleted together with some tapioca alone (B) or with some tapioca replaced by coarse soyabean meal (M) or finely ground soyabean flour (F). The diets were given at two levels to support 0.5 (L) and 1.0 (H) kg/d live weight gain. Chromic oxide and PEG were given as digesta flow markers. Mouth to abomasum digestibilities of different dietary sugars at the low level of intake (LB) were 0.65, 0.68, 0.59, 0.56 and 0.94 for arabinose, galactose, xylose, cellulose-glucose and starch-glucose respectively. Corresponding values at the higher level of intake (HB) were 0.55, 0.66, 0.55, 0.44 and 0.93 respectively. Supplementation with either soya bean meal or flour had no significant effects on the mouth to abomasum of dietary carbohydrate digestibilities at either level of feeding.
给装有简单瘤胃和皱胃瘘管的阉牛投喂等能量日粮，日粮由压碎的大麦和切碎的秸秆组成，单独与一些木薯粉（B组）或用粗大豆粉（M组）或细磨大豆粉（F组）替代部分木薯粉后制成颗粒饲料。日粮按两种水平投喂，以支持日增重0.5（低水平，L）和1.0（高水平，H）千克的活体重增长。以氧化铬和聚乙二醇作为食糜流动标记物。在低采食水平（LB）时，不同日粮糖类从口腔到皱胃的消化率分别为：阿拉伯糖0.65、半乳糖0.68、木糖0.59、纤维素 - 葡萄糖0.56和淀粉 - 葡萄糖0.94。在高采食水平（HB）时，相应的值分别为0.55、0.66、0.55、0.44和0.93。在两个采食水平下，添加大豆粉或大豆粕对日粮碳水化合物从口腔到皱胃的消化率均无显著影响。
