林草鸡复合系统对优质肉鸡生长及其环境的影响

实验测定了林草鸡复合系统对优质肉鸡生长及其对环境的影响.结果表明,低密度组鸡只生长发育良好,存活率高,牧草采食量高,提高了饲料转化效率,草地退化程度明显低于高密度组;高密度组香樟生长速度及土壤速效磷、速效钾含量均高于低密度放养,但牧草资源明显不足.建议在建立林草牧复合生态系统时要综合考虑生态环境、放牧密度和牧草种植等因素,以获得综合效益最优化和最大化.

Effect of the Silvopastoral System on Growth of Chinese Quality Broiler and Environment

This experiment determined the effect of growth and environments of Chinese quality broilers in the Silvopastoral System. The results showed that the quality broilers of low density group had fine growth and development and high survival rate;the low stocking density can increase the herbage intake and feed conversion ratio of quality broilers.The degradation degree of grassland in the low density group was significantly lower than that of high density group.The growth rate of trees and the soil available P...
