其他摘要：The free-range broiler production is an effective combination of ecological and economic benefits. However, excessive stocking will inevitably lead to a variety of negative effects, such as the destruction of vegetation, the hardening and even acidification of soil. It is very important to determine the reasonable stocking density for free-range broiler. In this paper, the outdoor feeding density of free-range broiler in different stocking ecosystems based on the nitrogen cycling was proposed combination of theoretical derivation and investigation and research, and proved the correctness of the research idea and density parameters through empirical research, which provided the key technical parameters for scientific guidance of free range chicken production.
