生猪动态营养需求研究现状及发展路径探讨

Research Status and Development Path Exploration of Dynamic Nutritional Requirements of Pigs

生猪动态营养需求研究是以特定生产目标为导向,基于生猪遗传因素、生长阶段、生理状态、所处生长环境、养殖规模、市场行情、猪肉品质等因素为生猪提供精准动态的营养供给。生猪动态营养需求研究是精准营养研究的进一步发展,通过拟合建立系列适用于准确预测不同状态下生猪营养需求和生产性能的动态模型,指导制定最佳生猪营养供给方案,进行生猪营养需求的动态精准供给,实现经济效益的最大化。本文梳理了生猪动态营养研究进展,结合生产实际分析了影响生猪动态营养需求的因素,探讨了生猪动态营养的实施路径及挑战。

The study on dynamic nutritional requirements of pigs is oriented by specific production goals,based on pig genetic factors,growth stage,physiological state,growth environment,breeding scale,market conditions,pork quality and other factors to provide precise and dynamic nutritional supply for pigs.The study on dynamic nutritional requirements of pigs is the further development of precise nutritional research,which can be fitted to establish a dynamic model for accurately predicting the nutritional requirements and performance of pigs under different conditions,and then guide the formulation of the best nutritional supply plan for pigs,achieve the real accurate supply of pig nutritional needs,improve economic benefits.This paper reviewed the research progress of dynamic nutrition in pigs,analyzed the factors affecting the dynamic nutritional requirements in combination with the actual production,and discussed the implementation path and challenges of dynamic nutrition for pigs.
