Brewer's spent grain (BSG) as a partial substitute for corn silage (CS) was evaluated in finishing feedlot steers on the lipid, protein, color, and microbiological stability of vacuum-packed meat for 75 days under refrigerated storage. Twenty steers were distributed in four treatments in a completely randomized design with five replicates each: 50% concentrate + 50% CS; + 35% CS + 15% BSG; + 25% CS + 25% BSG; and 15% CS + 35% BSG for 90 days. After the animals were slaughtered and the carcasses cooled, the Longissimus thoracis muscle was collected for analyzes. The lipid and protein oxidation, color parameters and microbiological stability of the beef although not affected by the diets (P > .05) oscillated throughout the storage time (P < .05). BSG can be included in the finishing diets of beef cattle by up to 35% (dry basis) and as a forage source without adverse effects on beef shelf life.

通过在冷藏条件下对真空包装肉类的脂肪，蛋白质，颜色和微生物稳定性进行整理，对育肥场ste牛的啤酒，废谷物（BSG）作为玉米青贮饲料（CS）的部分替代品进行了评估。在完全随机设计的20种ers牛中分配了四个处理，每个处理重复五次：50％浓缩物+ 50％CS；+ 35％CS + 15％BSG；+ 25％CS + 25％BSG；和15％CS + 35％BSG，持续90天。宰杀动物并冷却尸体后，收集胸肌Longissimus胸肌以进行分析。脂质和蛋白质氧化，颜色参数和牛肉虽然没有受到饮食（的微生物稳定性P 整个存储时间振荡> 0.05）（P <.05）。BSG最多可包含35％（以干基计）包含在肉牛的最终日粮中，并且作为草料来源，对牛肉的货架期无不利影响。
