Determination on Outdoor Stocking Density of Free-range Broilerin Different Ecosystems Based on Nitrogen Cycling

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