摘 要:[目的]为了探讨和观察FP4菌袋装青贮玉米秸调制及其饲喂肉牛育肥效果。[方法]以20头18-24月龄雄性西门塔尔杂交肉牛为试验对象,随机分为两组,进行FP4秸秆发酵活干菌青贮玉米秸与氨化麦秸肉牛育肥比较试验。两组日粮水平完全相同,试验组日饲喂袋装青贮玉米秸,对照组饲喂氨化麦秸。[结果]表明,试验组头均日增重为1170g,比对照组的892.4g提高23.7%。试验组头均纯收入为1051元,比对照组的585元多收入466元,经济效益提高了44.3%,收益显著。[结论]说明FP4菌袋装青贮玉米秸杆能显著提高饲养效益。To survey the procedures of corn silage prepared with FP4 bacteria and its effect on the beef finishing, 20 heads of 18-24 month age Simmental crossbred bulls were randomly divided into two groups and fed with corn silage prepared with FP4 bacteria and ammoniated wheat straw. Results showed that daily gain of the group fed with corn silage prepared with FP4 bacteria was 1170 g, which was higher than of the group fed with ammoniated wheat straw for 23.7 %. average income of the group fed with corn silage prepared with FP4 bacteria was ¥ 1051, which was higher than of the group fed with ammoniated wheat straw for 44.3%. It implied that it is possible to improve the income of beef cattle production by feeding with corn silage prepared with FP4 bacteria.
