摘　　要：为了考察膨化大豆复合营养舔砖对舍饲圈养山羊的应用效果,选用3月龄左右,体重、体高、体长和胸围相近,健康无病,生长发育良好的广西隆林黑山羊18只。采用对比试验安排,根据个体强弱、体重和体尺等,随机分为对照组和试验组两个组,每组3个重复,每个重复3只羊。结果表明:饲喂了舔砖的羊只健壮活泼,毛光亮顺滑,全期日增重较对照组提高了83.59%,差异显著(P<0.05);舔砖组体长增加量、体高增加量、胸围增加量各阶段均高于对照组,而且0～32d体长增长量、全期体长增加量舔砖组明显高于对照组(P<0.05);舔砖组山羊血清中总蛋白、白蛋白、尿素氮的浓度明显高于对照组(P<0.05),常量元素Ca、P、Na的浓度也显著高于对照组(P<0.05);舔砖组与对照组比,每只羊多净增纯利40.8元,投入产出比达1:1.69,经济效益非常可观。The experiment was conducted to study the production performances of extruded soybean muhinutrient blocks on captive goats. 18 healthy Guanxi Longlin black goats （3months of age） were randomly allotted into 2 treatments （control group and experimental group） with 3 replicates in each treatment.The resuhs showed that： extruded soybean multinutrient blocks improved average daily weight gain （ADG）,average body length,average body height and average chest circumference of goats significantly （P〈0.05）;It also improved TP,AIb,BUN ,Ca,P and Na in serum of goats significantly（P〈0.05） ;Economic benefit analysis showed that test group gained 40.8 yuan per goat more than control group . Input-output ratio was 1 ： 1.69.
