| 摘 要： | 对玉米及其秸秆采用 3种收获处理方式 :全株收获并青贮、基本成熟时收获子实后鲜秸秆及时青贮和完成成熟后收获子实干秸秆作为饲料。根据饲养标准 ,用玉米、鲜酒糟、豆粕等将玉米全株青贮饲料、鲜秆青贮饲料和干玉米秸秆分别配制成标准日粮 ,肥育架子牛 90d。试验结果表明 :日粮消化率、试牛日增重、产肉率及牛肉品质均以全株青贮日粮组为最好 ;养牛效益和每公顷耕地效益也以全株收获方式最好 ,鲜秆青贮次之 ,玉米完全成熟后收获子实干秸秆饲用方式最差。

| Abstract: | Corn and its stalk were harvested and processed with three methods which were whole crop silage on Sep.15th,fresh stalk silage on Sep.25th,dry stalk removed corn ears on Oct.5th respectively.The rations made up of three kinds of the roughages were used to feed beef cattle of two-year-old under the same nutritional level with corn and soybean meal etc.The results indicated that DG was 1282,1037 and 912 g respectively.Digestibility of diets and Beef production as well as meat quality in the whole crop silage group rank the first.The income of per cattle for fattening 90 days in three groups were 362.8,81.18 and 13.68 yuan.Those of per hectare were 11 878.08,7 296.84 and 5 306.04 yuan correspondingly. |
