采用体外模拟仔猪胃肠道环境的方法，用不同比例（0％～100％）的小麦替代玉米-豆粕（65∶25）型日粮中的玉米，并添加不同水平（0～10000 U/kg）的木聚糖酶，研究了小麦-玉米-豆粕型日粮中木聚糖的体外酶解。结果表明：在3种饲料原料中，小麦可溶性木聚糖含量最高，豆粕次之，玉米最低；随着日粮组合中小麦替代玉米比例的增加，日粮中可溶性木聚糖含量和总木聚糖含量均逐渐增加；各日粮组合中适宜的木聚糖酶添加水平均为6000 U/kg；以1/4玉米-3/4小麦-豆粕日粮组合较佳。

By using the method of simulating the gastrointestinal environment of piglets in vitro , replacing the corn in corn -soybean meal (65∶25) diet with different proportions (0%~100%) of wheat, and adding various levels (0~10000 U/kg) of xy-lanase into the mixed diet , the author studied the in -vitro enzymolysis of xylan in wheat -corn-soybean meal diet .The results in-dicated that:among 3 kinds of feedstuff , wheat contained the most soluble xylan , followed by soybean meal , and corn contained the least one;when the proportion of wheat for replacing corn in the mixed diet increased , the soluble xylan content and total xylan con-tent in the diet all increased gradually;the suitable adding level of xylanase into various mixed diets all was 6000 U/kg;the effect of 1/4 corn-3/4 wheat-soybean meal was better .
