The invention discloses a low-protein piglet daily ration premix using fermentation materials and a piglet daily ration containing the premix. The premix comprises the raw materials in percentage by weight as follows: 10%-15% of stone powder, 10%-15% of calcium hydrogen phosphate, 4%-8% of table salt, 10%-15% of L-lysine hydrochloride, 1%-3% of DL-methionine, 3%-5% of L-threonine hydrochloride, 1.0%-1.5% of a vitamin additive, 1%-3% of a microelement additive, 0.2%-0.3% of a growth promoter, 2%-4% of choline chloride, 0.5%-1.5% of a complex enzyme preparation, 0.2%-0.5% of high-temperature-resistant phytase, 0.3%-0.5% of an antioxidant, 10%-18% of medical stone and the balance of a carrier. The piglet daily ration is obtained by adding calcium hydrogen phosphate, whey powder, glucose, soybean oil, imported fish meal, extruded corn, northeast corn, fermentation materials, extruded soybeans and extruded soybean meal to the premix. The dosage of protein materials in feed can be reduced, the production performance of livestock and poultry is unchanged and slightly improved, the feed conversion rate, nitrogen deposition and nitrogen emission of livestock and poultry and stress capacityare improved, the breeding cost is reduced, the growth speed of pigs is increased, and the environmental pollution caused by pig excrement is reduced.
