摘　　要：为挖掘酒泉市肉牛产业发展潜力,筛选可提高饲草料利用率的科学饲喂方式,通过在养殖规模、软硬件设施和饲养管理水平各不相同的3个肉牛养殖场,分别采用机械加工全混合日粮、人工混合日粮和传统饲喂三种方式,连续饲喂肉牛200 d,分析对比各种饲喂方式增重效果。结果显示,饲喂机械加工全混合日粮较人工混合饲料和传统方式肉牛日增重分别提高9%和18%以上;差异均显著(P<0.05)和极显著(P<0.01)。试验表明,全混合日粮饲喂技术可显著提高肉牛日增重量,是一项可提高饲草料利用率,降低养殖成本,促进肉牛产业高质量发展的先进技术。In order to tap into the development potential of the beef cattle industry in Jiuquan City and screen for scientific feeding methods that can improve the utilization rate of forage,we used three different feeding methods:mechanical processing full mixed diet,artificial mixed diet,and traditional feeding in three beef cattle farms with different breeding scales,software and hardware facilities,and feeding management levels.We continuously fed beef cattle for 200 days and analyzed and compared the weight gain effects of various feeding methods.The results showed that compared to artificial mixed feed and traditional feeding methods,the daily weight gain of beef cattle increased by more than 9%and 18%,respectively;The differences were both sig-nificant(P<0.05)and extremely significant(P<0.01).Experiments have shown that the technology of fully mixed diet feed-ing can significantly improve the daily weight gain of beef cattle,which is an advanced technology that can improve the utiliza-tion rate of feed,reduce breeding costs,and promote the high-quality development of the beef cattle industry.
