Enthalpy thematic map interpolated with spline method for management of broiler chicken production

ABSTRACT Owing to the exponential growth of the human population and problems related to food supply, research focused on finding the most suitable approach to manage and geographically explore the environment using sustainable technologies stand out. The present study aims to produce a consistent interpolation of historical series of enthalpy (H) resulting in a thematic map of enthalpy, using the spline method as a kriging option in areas with few sampling points. The thematic map considers thermal comfort conditions to produce broiler chickens, that could be used as a management tool to reduce power consumption due to the cooling process of the facilities. It was verified that spline is an efficient method to create a suitable thematic maps representations of areas presenting a few sampled units. The geographical representation of enthalpy allowed the evaluation of the environments, concluding that the state of Mato Grosso do Sul, Brazil is inadequate for broiler chickens production without suitable thermal cooling systems. Evidence suggests introduction of aviculture in areas still unexplored, e.g., Chapadão do Sul and Sete Quedas.摘要 随着人口呈指数级增长以及粮食供应相关问题凸显，聚焦于利用可持续技术开展地理环境探索与环境管理的最优方案研究愈发受到重视。本研究针对采样点稀少的区域，以样条法（spline）作为克里金法（Kriging）的替代方案，对历史焓（enthalpy, H）序列进行一致性插值，进而生成焓主题地图。该主题地图结合肉鸡养殖所需的热舒适条件，可作为管理工具，用于降低养殖场冷却过程中的电力消耗。研究证实，样条法可高效为采样单元稀少的区域生成适配的主题地图可视化结果。通过焓的地理可视化可对养殖环境进行评估，研究得出结论：巴西南马托格罗索州（Mato Grosso do Sul）在未配备适配的热冷却系统的情况下，不适宜开展肉鸡养殖。研究证据表明，可在查帕当杜苏（Chapadão do Sul）与塞特凯达斯（Sete Quedas）等尚未开发的区域引入家禽养殖产业。
