| 摘 要： | 为阐明鸡、鸭对营养物质利用率差异的原因，研究了禽别（公鸡和公鸭）和消化道排空期（4、8、14、24、32、38、48 h）对消化道残留内容物含量的影响，比较食糜在鸡和鸭消化道不同部位的排空速度和排空率。结果表明：鸭排空速度比鸡快,但鸭消化道总残留干物质量和各段消化道残留干物质量都较鸡高；食糜在鸭小肠、直肠及整个消化道的排空率低于鸡的；鸭在强饲后24 h，鸡在32 h其内容物基本排空。在本试验条件下，用Sibbald的TME法测定饲料代谢能和氨基酸真消化率时，鸡的排空期定为32 h，鸭的排空期定为24 h为宜。

| Abstract: | A 2×7 factorial experiment was used to study the effects of animal (cockerel and drake) and removal period of digesta (4、8、14、24、32、38、48 h) on the residual amount of dry matter in digestive tract. The results indicated that the empting chyme in different part of the drake digestive tract were faster than that of cockerel. When removal period was 48h, there were more dry matters in drake digestive tract. Therefore, the collection time for cockerel was 32 and for drake was 24 h. |
