| 摘 要： | 本文采用了4头回－直肠吻合猪和3头正常猪研究了回－直肠吻合手术后第4－28周荷术猪的排泄频率及水的代谢变化，并与同期的正常猪比较。结果为：（1）荷术猪手术后第4－28周，食糜的排泄频率逐渐降低，食糜排泄次数从术后第4周的9.21次／d逐渐降低到术后第28周的6.58次/d。荷术猪肛门中食糜的排泄频率为正常猪的2.85倍。同时随着猪只日龄的增长，正常猪粪便的排泄频率也有下降的趋势；（2）荷术猪排泄物的含水量为正常猪的2.90倍；荷术猪术后4－28周间，排泄物中的含水量基本稳定，正常猪粪便中含水量也并未随猪只日龄增长而发生明显变化。

| Abstract: | WT5BZ]:The effects of ileal rectal anastomosis surgery and times post surgery on the water metabolism were investigated in 4 ileal rectal anastomosis(IRA) pigs and 3 intact(INT)pigs The results indicate:(1)From 4 to 28 weeks post surgery,the excreting frequency(times/d)of IRA pigs was decreased gradually from 9 21 to 6 58,The average excreting frequency of IRA pigs is 2 85 times of INT pigs.Meanwhile,the average excreting frequency of INT pigs had the similar trendency;(2)The dry matter content of digesta was 2 90 times of faeces,the dry matter contents of digesta and faeces were relatively constant during the whole experiment. |
