The invention discloses biological feed for above 30 kg Sichuan and Tibet black pigs and complete feed containing the same. The biological feed is prepared by performing sealed fermentation on a feed raw material with the total water content of 15-35% for 3-7 d at the temperature of 20-35 DEG C; and the feed raw material comprises 0.05-0.2 part of saccharomyces cerevisiae, 0.05-0.2 part of lactobacillus acidophilus, 0.05-0.2 part of bacillus subtilis, 150-250 parts of soybean meal, 100-200 parts of soybean hull, 200-350 parts of wheat bran, 100-250 parts of rapeseed meal and 50-200 parts of rice bran meal. The complete feed contains 3-6% of biological feed. The biological feed is researched and developed in allusion to needs in aspects of daily gain, flavored amino acids and intramuscular fat accumulation of the Sichuan and Tibet black pigs, so that fattening requirements of the above 30 kg Sichuan and Tibet black pigs can be met, the characteristics in aspects of flavor and mouth feel of pork can be ensured, and the pork quality is improved.
