摘　　要：我国肉猪生产水平落后于国际先进水平,与猪的遗传潜力相比差距更大,根本原因是吃不够发挥潜力的营养物质或营养供给模式不适应猪的生物学特点。文章在讨论饲料转化效率(FCR)重要性基础上,分析了猪的营养生理特点和饲料供给现状,提出营养变革可使肉猪全程FCR实现2.0的目标。重点介绍了3F(Formulation、Fermentation、Fluid Feeding)营养技术内涵及应用效果,为深入研究猪的营养问题、提高生产水平提供参考。Pig production from birth to market in China is falling behind the world best,and furthermore,far away from pig genetic potential.The fundamental reason is that the nutrient intake or nutrient supply manner is not in line with pigs’biological characteristics.After emphasizing the importance of feed conversion rate(FCR),this review analyzes the pigs’nutritional physiology and feed supply condition,proposes the idea that nutritional reformation allows pig FCR to reach 2.0,and introduce creatively 3F nutritional strategy and its connotation and application.The article will be a reference and promotion for further research of pig nutrition and improvement of pig production performance by nutritional strategy.
