Abstract

Digestibility of fibre was higher in guinea-pigs than in rabbits, however, the digestibility of hemicellulose fraction containing agar was similar in both animals. 2. The digestibility of fibre of a fine particle diet was higher than that of a large particle diet in the rabbit permitted coprophagy, whereas it was lower in the rabbit prevented from coprophagy. 3. The fine particle diet tended to cause shorter retention time of digesta in the rabbit prevented from coprophagy. 4. These suggest that the digestibility of fine components relates to their physical properties which affect the retention time of digesta in the rabbit.

摘要

豚鼠体内纤维的消化率高于兔子，然而，含琼脂的半纤维素部分在两种动物体内的消化率相似。2. 在允许食粪的兔子中，细颗粒饲料的纤维消化率高于大颗粒饲料，而在被阻止食粪的兔子中则较低。3. 细颗粒饲料往往会使被阻止食粪的兔子的消化物停留时间缩短。4. 这些表明，精细成分的消化率与其物理性质有关，这些物理性质会影响兔子体内消化物的停留时间。
