| 摘 要： | 以醋酸纤维素为纤维源配制成粗纤维水平分别为２．０％、５．０％、８．０％的３种无氮日粮，采用３头回—直肠吻合猪，分３期试验，通过３×３拉丁方设计研究在等进食量（７５０ｇ／ｄ）条件下日粮的纤维水平对回—直肠吻合猪消化道内源氨基酸测值的影响。结果表明：除缬氨酸、异亮氨酸和胱氨酸外，无氮日粮的粗纤维水平对回肠末端食糜干物质中其他内源氨基酸含量（％）无显著影响（Ｐ＞０．０５）。而对回肠末端内源氨基酸的总排泄量影响显著（Ｐ＜０．０５）或极显著（Ｐ＜０．０１）。相关分析表明，粗纤维水平与各种内源氨基酸的排泄总量之间存在显著（Ｐ＜０．０５）或极显著（Ｐ＜０．０１）的强相关关系，随无氮日粮中粗纤维水平的升高，各种内源氨基酸排泄量呈直线增加。

| Abstract: | In order to study the effect of dietary fibre levels(2%,5%,8%)on ileal endogenous amino acid flow,3 ileo-rectal anastomosis pigs were employed in a 33 latin square design trials.The results indicated that dietary fibre levels showed no apparent effect(P>0.05) on the content of endogenous amino acid in dry matter of ileal digesta,except for valine,isoleucine and cystine.However,the addition of cellulose signficantly decreased the digestibility of dry matter and increased ileal endogenous N and animo acid flow,there are extremely significantly correlationship(P<0.01) between dietary fibre levels in N free diets and terminal ileal endogenous amino acid flow in pig. |
