【Abstract】 By using system analysis and linear program model, the paper predi-cted the optimum structure of future layer breeding system in Beijing, in orderto make use of existing feed resources, production funds and chicken houses, andmaximize the economic efficiency of layer production. The sensitivity analysiswas made. It also analyzed the feasibility and available mating forms of theoptimum strucure, which provided a scientific basis for programming and policymaking of layer production in Beijing.更多还原
