| 摘 要： | 本试验选用黔江县川南山地黄牛阉公牛 12头 ,随机分成 3组 (两个试验组 ,一个对照组 )进行放牧和放牧加补饲的肥育试验。经过 60d的试验 ,两个试验组 (分别补饲混合精料和补饲单一精料 )的ADG分别为 595.83g和 4 94 .17g ,比对照组的ADG 155.83g分别提高了 2 82 .36%和2 17.12 % ,肥育毛利润分别为 75.59元 /头和 53.2 4元 /头 ,比对照组的 4 6.75元 /头分别增加 2 8.84元 /头和 6.4 9元 /头。补饲混合精料组的精料增重比 ( 2 .86 1)比补饲单一精料组的精料增重比 (3.52 1)下降 18.75%。试验结果表明 ,与放牧相比 ,放牧加补饲 (尤其是补饲混合精料 )能极显著提高日增重、缩短肥育时间、增加经济效益 ,是山区农村发展牛只肥育的一种较好方式

| Abstract: | bullocks of Chuannan yellow cattle randomly were assigned to three groups including two experimental groups(concentrate supplementary feeding groups) and one control group(grazing group) to this fattening experiment.The result of the sixty day experiment showed that average daily gain of two experimental groups was 595.83 g and 494.17 g respectively, improving 282.36% and 217.12% in comparison with that of control group (155.83 g), gross profit per animal of fattening were 75.59 yuan and 53.24 yuan respectively, improving 28.84 yuan and 6.49 yuan by contrast to that of control group ( 46.75 yuan).This experiment showed that the concentrate supplementary feeding could remarkably promote daily gain,reduce fattening time,add to income. It will be a good way of cattle fattening in countryside . |
