摘要(Abstract)：

采用肉鸡常用的玉米和小麦型两种日粮,三个制粒温度梯度(80、85、90℃)进行了颗粒饲料质量比较研究。结果表明:制粒温度提高,可以提高颗粒饲料的PDI、MPDI、硬度和淀粉糊化度(P<0.05),随着制粒温度的升高(80~90℃),无论是玉米型和小麦型日粮,均可以改善颗粒饲料的品质;从颗粒饲料质量比较,小麦型日粮优于玉米型日粮(P<0.05)。采用4种不同的粉碎机筛片(1.0、1.5、2.0、2.5 mm),粉碎大宗原料(玉米、小麦、豆粕),获得4种几何平均粒径(378、430、516μm和590μm)的粉状饲料,研究粉碎粒度对颗粒饲料品质影响。结果表明:本研究条件下的粉碎粒度没有影响颗粒饲料的品质(P>0.05)。研究结论:制粒温度的升高可以改善颗粒饲料的品质,尤其是小麦型日粮。粉碎粒度没有影响颗粒饲料的品质。
