摘要

The objective was to evaluate the replacement of barley-based ingredients with short-season high-moisture corn products on steer growth performance and carcass characteristics. Over 2 years, 320 beef steers (528 ± 36.2 kg initial body weight) were assigned to 32 pens (4 pens/treatment/year). Treatments were finishing diets that contained dry-rolled barley grain and barley silage (BGBS; control), barley grain and corn silage (BGCS), high-moisture shelled corn and barley grain with barley silage (HCBS), or snaplage (included as a silage and grain source) with barley grain (SNAP). Steers were fed for 99 days and 72 days in years 1 and 2, respectively. Steers fed BGCS did not differ (P ≥ 0.13) from BGBS for dry matter intake, average daily gain, gain:feed, or carcass characteristics. Steers fed HCBS had greater (P ≤ 0.05) hot carcass weight and dressing percentage than BGBS. A lesser (P = 0.02) proportion of steers fed SNAP had severe liver abscesses than BGBS. We concluded that corn silage can replace barley silage, 50% replacement of barley grain with high-moisture shelled corn may improve hot carcass weight, and replacement of barley silage and some barley grain with snaplage decreases the proportion of cattle with severe liver abscesses at slaughter.

目的是评估用短季节的高动物玉米产品替代基于大麦的成分，以进行转向增长性能和car体特征。在2年的时间里，将320个牛肉ste牛（528±36.2 kg初始体重）分配给32张笔（4笔/治疗/年）。治疗方法是饮食中含有干卷的大麦谷物和大麦青贮饲料（BGB；对照），大麦谷物和玉米青贮饲料（BGC），高油源壳玉米和大麦谷物，带大麦青贮饲料（HCBS）或Snaplage（包括青贮饲料和谷物源）带大麦谷物（快照）。在第1和2年内，牛头分别为99天和72天。在干物质摄入量，平均每日增益，增益：进料或car体特征方面，饲喂BGC的转向与BGB没有差异（P≥0.13）。饲喂HCB的转向器比BGB具有更大（P≤0.05）的热cas体重量和敷料百分比。与BGB相比，饲喂快照的牛仔脓肿较少（p = 0.02）的比例较轻。我们得出的结论是，玉米青贮饲料可以替代大麦青贮饲料，用高含量的玉米替代大麦谷物的50％可以改善热car体的重量，并替换大麦青贮饲料和一些大麦谷物，而大麦谷物则可以减少牛的比例。
