【摘要】 模拟肉鸭胃肠道内环境,采用两步离体消化法,分别研究了三种酶制剂(β-葡聚糖酶、纤维素酶和木聚糖酶)的6个水平(0、100、300、500、700、900μg/g)对稻谷离体消化能值的影响。结果表明:β-葡聚糖酶(x1)、纤维素酶(x2)、木聚糖酶(x3)的添加水平显著提高了稻谷离体消化能值(Y)(P<0.05),其二次回归关系分别为Y=-1E-06 x12+0.001 2 x1+6.695 9(R2=0.863 8,n=6,P<0.05),Y=-1E-06 x22+0.0018 x2+6.7502(R2=0.8668,n=6,P<0.05),Y=-1E-06 x32+0.0016 x3+6.6634(R2=0.954 8,n=6,P<0.05),从而确定出在试验条件下,β-葡聚糖酶、纤维素酶和木聚糖酶的最适添加量分别为600、900和800μg/g。
【英文摘要】 Simulating the gastrointestinal tract environment of ducks and adopting the digestion method in vitro,the effects of several enzymes on the digestion energy in vitro for paddy in ducks were studied;the enzymes were β-glucanase,cellulose and xylanase,added to diets at doses of 0,100,300,500,700,900μg/g,respectively.Results show that the supplementation of β-glucanase(x1), cellulose(x2) and xylanase(x3) significantly improve(P<0.05) the digestion energy in vitro for paddy(Y).Their quadratic regression equatio...
