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～ 2 8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～ 2 8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 2 1次 /d逐渐降低到术后第 2 8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～ 2 8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。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.
