摘　　要：在南方亚热带人工草地上以云岭黑山羊为试验家畜,进行不同季节、不同牧压下的草场供给量、山羊采食量和山羊日增重的测定。结果表明:山羊日增重依赖于采食量,随着采食量的增大,山羊日增重也随之升高;高载畜率组山羊平均日增重为78 g/d,低载畜率组山羊平均日增重为113 g/d,高载畜率组较低载畜率相差44.9%,两者差异显著(P<0.05);牧草品质会影响放牧山羊采食量。Studies on the relationship among Yunling black goats intakes, pasture allowance and daily gains under the different grazing inten- sifies and different grazing seasons were conducted on the subtropical cultivated pastures in Southern China. The results showed that the goats daily gains depended on feed intakes and got to be increased as the intakes went up. Average daily gains of heavy-grazing and light-grazing goats were 78 g/d and 113 g/d respectively and the difference was 44.9 %. The difference between the heavy-grazing and light-grazing treatments was significant （ P 〈 0.05）. Forage quality could affect the goat intakes.
