本试验研究了苜蓿草粉纤维水平和取样时间对生长猪氨基酸表观回肠消化率（AID）和标准回肠消化率（SID）的影响。将总计24头回肠插管猪（Durocx（Large WhitexLandrace），体重（21.4 +/- 1.5）kg）随机分配至4个处理组。在两个为期10天的试验期间，猪提供玉米-豆粕日粮或含有5，10 - 01 - 20%的苜蓿粉的日粮。测定AA的AID。6头回肠插管猪饲喂无蛋白饲料，以估计AA的内源性蛋白质损失和SID。日粮中添加5%和10%苜蓿草粉对回肠AA消化率无显著影响（P>0.05）。组氨酸、赖氨酸、蛋氨酸、苯丙氨酸、苏氨酸、瓦尔、丙氨酸、天冬氨酸、半胱氨酸、甘氨酸、脯氨酸、丝氨酸和酪氨酸的AID随苜蓿草粉添加量的增加而降低2.0-6.8%（线性，P
Two experiments were conducted to determine the effects of fiber level from alfalfa meal and sampling time on the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids (AA) in growing pigs. A total of 24 ileal-cannulated pigs (Durocx(Large WhitexLandrace) with body weight (21.4 +/- 1.5) kg) were randomly allotted to 4 treatments. The pigs were provided a corn-soybean meal diet or a diet containing 5, 10 01 20% of alfalfa meal during two 10-d experimental periods. The AID of AA was measured. Six ileal-cannulated pigs were fed a protein-free diet in order to estimate the endogenous protein losses and SID of AA. Ileal AA digestibility was not affected by inclusion of 5 or 10% alfalfa meal in the diet (P>0.05). The AID of His, Lys, Met, Phe, Thr, Val, Ala, Asp, Cys, Gly, Pro, Ser and Tyr reduced by 2.0-6.8% with the addition level of alfalfa meal (linear, P
