| 摘 要： | 本研究用4头12周龄 ,体重32kg 左右的回—直肠吻合阉公猪 ,测定了回—直肠吻合术后第4、第9、第11、第13、第18周日粮中钠和钾的消化率和代谢率。结果为 :①回—直肠吻合术后第4周～第18周 ,钠的消化率和代谢率都较稳定 ,差异不显著(P>0.05) ,分别稳定在23.11 %和21.38 % ,表明在本试验条件下 ,荷术猪对日粮中钠的消化和代谢处于一个稳定的状态 ;②术后第4周～第18周 ,钾的消化率和代谢率均呈下降趋势 ,钾的消化率从术后第4周的32.72 %下降至术后18周的1.46 % ,钾的代谢率则相应地从30.46 %下降至 -0.77 % ,表明在本试验条件下 ,回—直肠吻合荷术猪体内钾的消化与代谢随着术后时间的延长存在一定的变化

| Abstract: | Four 12-week old 32kg ileo-rectal anastomosis barrows were used to determine the digestibility and metabolizability of dietary sodium and potassium in the 4th,9th,11st,13rd and 18th week post-surgery.The results were:(1)the digestibility and metabolizability of sodium were relatively constant from the 4th week to the 18th week post-surgery,indicating that the metabolism of sodium was under steady condition in this experiment;(2)the digestibility and metabolizability of potassium were decreased gradually from 32.72% and 30.46% in the 4th week to 1.46% and -0.77% in the 18th week,indicating that the metabolism of potassium were changed.The reason was analyzed and the suggestion of how to add sodium and potassium was presented. |
