Abstract: Amid growing food security concerns，tightening environmental policies，and the demand for sustainable animal husbandry，low?protein，low?soybean?meal diversified diet technology for pigs has become a major research focus in the industry. This technology is grounded in the net energy and balanced amino acid nutrition theory. By precisely supplementing synthetic amino acids，soybean meal inclusion is reduced，and dietary crude protein level are lowered by 2%-4%. Through pretreatment of soybean meal alternatives，addition of functional additives，the optimization of processing techniques，and application of dynamic formulation models，anti?nutritional factors are effectively mitigated，utilization of unconventional protein sources is enhanced，and synergistic balance among dietary nutrition，cost，and environmental benefits is achieved. This paper comprehensively elaborates on the theoretical basis and key technologies for formulating low?protein，low?soybean?meal diversified diets for pigs，providing technical reference for the low?carbon transformation of the pig breeding industry.
