摘　　要：用膨润土、食盐、尿素、糖蜜、磷酸氢钙和硫酸钠等为主要原料制作成复合营养舔块来研究其对山羊增重效益的影响。结果表明,试验组每只羊平均日增重提高了69.57%,且差异极显著(P<0.01)。试验组平均每只羊净增效益46.08元,提高了55.81%。饲喂这种复合营养舔块投入产出比可达1:4.06,经济效益显著。Study on effect increased weight by compound nutrition block which composed salt, the urea, the molasses, the calcium hydrogen phosphate and the sodium sulfate. The result ly weight of experimental group each sheep increased extremely significantly 59.83 g, improv Every goat net income of experimental group was ~ 46.08, improved 55.81%. Input-output rati the compound nutrition block, economic efficiency was remarkable.
