橡胶林下饲养密度对瑶鸡生长性能的影响

The Effect of Stocking Density on Growth Performance of Broiler Chicken in Hevea Rubber Plantations

在云南德宏橡胶林下开展不同饲养密度对瑶鸡生长的影响试验,结果表明:1∶1、1∶2两种饲养密度对瑶鸡的采食量和料重比有显著影响,但对瑶鸡的平均增重、总增重、出栏体重无显著影响。高密度(1∶2)的鸡数量多而获得低料重比、高出栏总重的效果。德宏橡胶林下放养瑶鸡较适的饲养密度为1∶2,即2只鸡/m^2,既能充分利用橡胶林下空间,又能使鸡群表现出较好的生长性能。

Stocking density effects on growth performance of broiler chicken was carried out under rubber forest in Dehong of Yunnan Province. Although two treatments have significant effect on feed intake and feed-weight ratio of broiler chicken, there is no significant effect on average gain, total gain and marketing weight. The results indicated that higher stocking density （two chickens every square meter） can not only take full advantage of the space of forest, but also can make good growth perfor- mance of broiler chicken, more chickens, low feed-weight ratio and high total marketing weight.
