【摘要】:根据甘肃高山细毛羊母羊妊娠后期营养缺乏状况,配制出中等能量中等蛋白质补饲料Ⅰ、低能量高蛋白质补饲料Ⅱ和高能量低蛋白质补饲料Ⅲ3种补饲料。选择健康、体重相近的妊娠后期母羊60只,随机分为A、B、C、D4组,每组15只,每个重复1只羊,A、B、C组为试验组,分别补饲饲料Ⅰ、Ⅱ和Ⅲ;D组为对照组,按牧民传统方式饲养,试验期共68d。试验结果表明,A、B、C补饲组母羊平均日增重分别为102、109和114g/d;A、B、C补饲组羔羊初生重分别为4.09、3.91和4.40kg,均显著高于对照组。补饲料Ⅲ对试验羊血清葡萄糖(glucose)、甘油三酯(triglyceride)和尿素氮(blood urea nitrogen)浓度有显著影响(P0.05);补饲料Ⅱ对试验羊血清总蛋白(total protein)、谷草转氨酶(aspartate transaminase)浓度有显著影响。补饲组试羊瘤胃液总氮、瘤胃液蛋白氮含量显著高于对照组(P0.05)且A组显著高于其他各组,B组瘤胃液尿素氮浓度显著高于其他各组(P0.05)。试验组瘤胃液挥发性脂肪酸(volatile fatty acid)浓度和丙酸摩尔比显著高于对照组(P0.05);试验组瘤胃液中乙酸/丙酸显著低于对照组(P0.05)。3种补饲料对试验羊瘤胃液pH和瘤胃液氨态氮影响均不显著(P0.05)。
