林下养鸡与工厂化养鸡的初步比较

摘要

The preliminary comparison in raising chickens between wild and factory is carried through in this paper. The growth cycle of wild chicken is 150 - 180 days while that of factory chicken is 56 - 63 days. The crop rate of wild chicken is superior to that of factory chickens, but the death rate and disability rate are greatly under those of factory chicken. The wild chicken shows great economic and ecological benefits. The unclertak- ing of wild chicken could be well developed because the natural conditions of mountain areas in Guizhou are suitable to wild chicken.%对林下养鸡和工厂化养鸡进行初步比较,结果表明：林下养鸡的生长周期为150～180天,而工厂化养鸡为56～63天。林下养鸡的死亡率和致残率均低于工厂化养鸡,因而具有很高的出栏率。林下养鸡具有良好的经济效益和生态效益。贵州山区具有林下养鸡的天然有利条件,发展林下养鸡大有作为。
