摘要：随机选出3月龄、体重相当的40只羊，试验组20只用全混合日粮饲喂，日均增重0.262 kg，料重比4.59：1，对照组20只羊用传统的精粗分饲方法喂养，日均增重0.212 kg，料重比5.14：1。结果表明全混合料技术饲料利用率优于传统饲喂技术。根据当地肉羊养殖技术习惯，全混合日粮饲喂在中小规模羊场的应用并不普遍，通过在示范场进行全混合日粮饲喂试验带动周边养羊户应用全混合日粮进行肉羊育肥，能实现技术推广和增产增收的双重目标。

Abstract：Forty sheep were randomly selected at 3 months of age and of comparable body weight. 20 sheep in the experimental group were fed with the total mixed diet，with an average daily weight gain of 0.262 kg and a feed-to-weight ratio of 4.59：1，while 20 sheep in the control group were fed with the traditional method of rough and fine feeding，with an average daily weight gain of 0.212 kg and a feed-to-weight ratio of 5.14 ：1.The results showed that the feed utilization rate of the total mixed diet technology was better than that of the traditional feeding technology. According to the local meat sheep breeding technology，the application of full mixed diet feeding in small and medium scale sheep farms is not common.By conducting full mixed diet feeding trials in demonstration farms to drive neighboring sheep farmers to apply full mixed diet for meat sheep fattening，the dual objectives of technology promotion and increasing production and income can be achieved.

0引言

全混合日粮（TMR）是根据反刍动物不同阶段营养需要设计饲料配方，将所有原料按顺序混合均匀而成的一种营养平衡的全价日粮。采用TMR搅拌机对组分进行搅拌、切割和揉搓，充分混合后能保证反刍动物所采食的饲料精粗比恒定，营养相对平衡，做到科学喂养。TMR饲喂技术已经推广多年，但在生产应用中受思想观念守旧、成本核算意识不强、设备投资大等因素困扰，在本地中小型羊场中应用并不普遍。开展试验的宝丰羊场存栏量980只，以自繁自养为主，育肥羊饲养一直是传统的精粗分饲方法。为保障试验对比效果，试验中TMR配料均为该场日常用原料。

1材料与方法

1.1试验时间及地点

本试验于2020年4月1日至6月28日在灌云縣宝丰羊场进行，预试期7 d，正试期88 d。

1.2供试羊选择及分组

选择40只3月龄商品代湖羊，营养状况良好，健康且体重基本一致，试验羊进行预防性驱虫，经统一编号、称重登记后随机分为2组，每组20只，各组间总体重接近，公母比例相同。……
