在群体控制试验的基础上研究了放养条件下柴鸡的饲料需求情况,并探究了浑善达克沙地放牧柴鸡对草地生产力的影响.结果表明,在草原上放牧柴鸡,能够节省26%的饲料粮,"草原牧鸡"模式下的柴鸡每产出1kg毛鸡比笼养模式下的柴鸡少消耗饲料1.48kg;在草原上放牧柴鸡,对草场生产力的影响较小,显著低于放牧牛羊,有利于退化草地植被的恢复,还能够增加牧民的经济收入,"草原牧鸡"模式下,每公顷草场可比传统放牧模式收入高1500元左右;另外,"草原牧鸡"模式产出的大量生态有机柴鸡肉和柴鸡蛋产品能够满足人们对健康食品的需求.
The feedstuff consumption of chickens grazing on the Hunshandake Sandland was investigated through a control experiment. The impacts of chicken grazing on the productivity of the grassland was also identified. The result showed that farming of chickens on the grassland could save about 26% of the total feedstuff, which meant, to produce 1kg meat the free-range chicken could save 1.48kg feedstuff comparing with cage-raising chicken. Chicken grazing on the grassland had a little effect on the productivity of grassland which is much lower than the impacts of cattle and goat grazing. Chicken farming on the grassland is not only good for restoration of the degenerating grassland vegetation, but it could improve the income of local herdsman. The data demonstrated that the profit per hectare with this mode was about 1500 Yuan RMB higher than that with traditional grazing mode. Meanwhile, the outputs of this mode, including organic chickens and eggs, could meet the increasing need for healthy food.
