Non-grain protein source pig feed and preparation method thereof

The invention relates to the technical field of pig feed, and discloses non-grain protein source pig feed and a preparation method thereof. The feed is prepared from the following raw material components in percentage by mass: 45-50% of corn, 5-10% of wheat, 0.1-0.3% of grease, 5-8% of bran, 8-10% of bran meal, 0.8-1% of stone powder, 6-10% of rapeseed meal, 3-5% of insect protein powder, 3-5% of algae protein powder, 2-3% of zygosaccharomyces adhattai, 1.5-2% of an amino acid supplement, 0.2-0.5% of a vitamin supplement and 0.05-0.2% of a mineral supplement. Wherein the amino acid supplement is prepared from the following components: lysine, threonine, methionine, valine, isoleucine, tryptophan, phenylalanine and histidine; the pig feed has the advantages of ensuring that amino acids ingested by pigs are balanced and comprehensive, enhancing digestion and absorption functions of the pigs and reducing gastrointestinal diseases of the pigs. 本发明涉及猪饲料技术领域，公开了一种非粮蛋白源猪饲料及其制备方法，由如下以质量百分比计数的原料组分制成：玉米45～50％、小麦5～10％、油
