| 摘 要： | 本试验在三峡库区丰都县选用川南山地黄牛 1 2头 ,随机分成 3组 ( 2个试验组 ,1个对照组 ) ,进行放牧和放牧加补饲的增重试验。经过 60 d的试验 ,2个试验组的平均日增重 ( ADG)分别为 5 4 4.5 8g和 60 2 .92 g,比对照组的 1 37.92 g分别提高 2 94.85 %和 337.1 5 % ;增重毛利润分别为 5 2 .45元 /头和 80 .31元 /头 ,比对照组的 41 .40元分别增加 1 1 .0 5元 /头和 38.91元 /头。试验结果表明 ,与放牧相比 ,放牧加补饲能显著提高日增重 ,增加经济效益

| Abstract: | Twelve yellow cattle were selected and randomly divided into 2 treatment groups and 1 control group. After 60 days, average daily gains of two treatment groups were 544.58 g and 602.92 g, which were 294.85% and 337.15% higher than that of the control group (137.92 g), respectively. Average gross profits of body weight gain per cattle were $52.45 and $80.31, which were increased by $11.05 and $38.91 than $ 41.40 of the control group. These results demonstrated supplementary feeding could improve average daily gain and economic profit comparing to grazing. |
