1不同来源瘤胃保护蛋氨酸对泌乳奶牛产奶量和氮利用率的影响显示文摘试验旨在确定以异丙基-2-羟基-4-(甲硫基)-丁酸(HMBi)或瘤胃保护蛋氨酸(RPM,反刍蛋氨酸,美国乔治亚州阿尔法瑞塔市安迪苏公司生产)形式提供可吸收蛋氨酸与2-羟基-4-(甲硫基)-丁酸(HMBi)一起饲喂或不一起饲喂泌乳奶牛的产奶量反应,并确定添加蛋氨酸是否允许给奶牛饲喂粗蛋白低日粮。70头奶牛根据胎次和泌乳天数分成14个组,随机分配为以苜蓿、玉米青贮和高水分玉米为基础日粮的处理:①日粮含粗蛋白15.6%、不添加蛋氨酸(负对照组);②日粮含粗蛋白15.6%+HMBi0.17%;③日粮含粗蛋白15.6%+RPM0.06%+HMB0.10%;④日粮含粗蛋白15.6%+RPM0.06%;⑤日粮含粗蛋白16.8%、不添加蛋氨酸(正对照组)。假定摄取的HMBi50%从胃肠道被吸收,RPM中80%蛋氨酸被小肠吸收。试验结果表明,添加HMBi和RPM增加可代谢蛋氨酸供给9g·d-1,赖氨酸与蛋氨酸比率从3.6降低到3.0。在2周的协变量期(期间所有奶牛饲喂相同的日粮)之后,给奶牛饲喂试验日粮12周。试验结果表明,日粮不会影响奶牛的干物质采食量(平均数±标准差,25.0±0.3kg·d-1)、体增重(0.59±0.2kg·d-1)、产奶量(41.7±0.6kg·d-1),然而,饲喂HMBi可提高奶牛能量校正奶产量、乳蛋白产量和无脂固形物产量。而且,添加蛋氨酸的3种日粮,观察到奶牛乳脂含量、脂肪和真蛋白产量有提高的趋势。RPM处理组的表观氮效率(牛奶氮/吸收氮)最高。饲喂粗蛋白16.8%、不添加蛋氨酸的奶牛乳中尿素氮与尿素氮和总氮的尿排泄提高,表观氮效率从34.5%下降到30.2%,而没有改善产奶量。试验结果表明,饲喂HMBi或RPM奶牛的产奶量和氮利用率获得相似的改善。Broderick G A Luchini N D Sloan B K Devillard E 张树金 2011饲料博览2011,,10:2
