Rations with dried feedstuffs and rations with between 30 and 50% raw potatoes in the dry matter as well as steamed potatoes and sugar beets, sucrose and apple pectin were tested in measurings of the total metabolism in growing pigs with ileo-rectal anastomoses. The prececal digestibility of the energy of the rations ranged between 42% (rations with raw potatoes) and 79% (rations with sucrose). The digestibility of the rations with a 50% quota of steamed potatoes was better by 30%--units than that of rations with raw potatoes. In addition to crude nutrient digestibility, data are given on the digestibility of starch, water soluble carbohydrates and pectin. The wide variation in the N retention of 6-25 g/animal.day can only be partly connected with energy retention. Urine energy amounted to between 2.5 and 5% of gross energy. The average utilization of metabolizable energy amounted to 69.4%. A connection is to be seen with the value of energy maintenance requirement of 646 kJ retention energy/kg LW0.62.d.
在对患有回直肠吻合术的生长猪进行总代谢测定时，测试了含有干饲料的日粮、干物质中含有30%至50%生土豆的日粮以及蒸煮土豆、甜菜、蔗糖和苹果果胶的日粮。日粮能量的盲肠前消化率在42%（含生土豆的日粮）至79%（含蔗糖的日粮）之间。含50%蒸煮土豆配额的日粮消化率比含生土豆的日粮高30个百分点。除了粗养分消化率外，还给出了淀粉、水溶性碳水化合物和果胶的消化率数据。每头动物每天氮保留量在6 - 25克之间的巨大差异只能部分与能量保留相关。尿能占总能的2.5%至5%。可代谢能量的平均利用率为69.4%。这与能量维持需要量为646千焦保留能量/千克体重0.62·天的值有关。
