Abstract
- The rate of passage of chromic oxide (Cr) was similar in the pony and rhinoceros. 2. Higher apparent amounts digested were found using 4N-HCl-insoluble ash (AIA) than those determined by Cr, but overall digestibilities were similar for the two species. 3. An abrupt increase in the starch content of the horse diets increased the number of faecal ciliate protozoa. Only when the overall feed intake was increased in horses receiving a high dietary proportion of starch were the numbers depressed. 4. When the rhinoceros received 109 kJ apparent DE per kg bodyweight daily (716 kJ/W0.75 daily) it maintained normal condition.
摘要
- 氧化铬（Cr）在小马和犀牛体内的通过率相似。2. 使用4N盐酸不溶性灰分（AIA）测定的表观消化量高于用Cr测定的量，但两种物种的总体消化率相似。3. 马日粮中淀粉含量的突然增加会使粪便纤毛虫原生动物数量增加。只有当采食高淀粉日粮的马的总采食量增加时，这些数量才会减少。4. 当犀牛每天每千克体重摄入109千焦表观消化能（每日716千焦/W0.75）时，它能维持正常状态。
