Examples
Embodiment 1
[0021] This example is used for the biological feed of Sichuan-Tibet black pigs with a full feed of more than 30kg, which is prepared from feed materials with a total water content of 30% at a temperature of 25°C, sealed and fermented for 5 days; wherein the feed materials contain the following parts by weight Ingredients: 0.1 part of Saccharomyces cerevisiae, 0.1 part of Lactobacillus acidophilus, 0.1 part of Bacillus subtilis, 200 parts of soybean meal, 150 parts of soybean hull, 300 parts of wheat bran, 150 parts of rapeseed meal, 200 parts of rice bran meal. Feed ingredients generally contain 12-15% water, and the part with insufficient water content is added to 30%.
[0022] In the biological feed after fermentation, the number of viable bacteria ≥2.0×10 9 Pieces / g, organic acid ≥2.0%.
[0023] The soybean meal, soybean hulls, bran, rapeseed meal, and rice bran meal are crushed before being fermented, and the crushed sieve pieces are all 1.0×1.0 mm.
Embodiment 2
[0025] This embodiment is used for the biological feed of Sichuan-Tibet black pigs with a total feed of more than 30kg. It is prepared from feed materials with a total water content of 35% at a temperature of 20°C and sealed and fermented for 7 days; wherein, the feed materials contain the following parts by weight Ingredients: 0.05 parts of Saccharomyces cerevisiae, 0.15 parts of Lactobacillus acidophilus, 0.15 parts of Bacillus subtilis, 220 parts of soybean meal, 130 parts of soybean hulls, 300 parts of wheat bran, 180 parts of rapeseed meal, 180 parts of rice bran meal. Feed ingredients generally contain 12-15% water, and the part with insufficient water content is added to 35%.
[0026] In the biological feed after fermentation, the number of viable bacteria ≥2.0×10 9 Pieces / g, organic acid ≥2.0%.
[0027] The soybean meal, soybean hulls, bran, rapeseed meal, and rice bran meal are crushed before being fermented, and the crushed sieve pieces are all 1.0×1.0 mm.
Embodiment 3
[0029] This embodiment is used for the biological feed of Sichuan-Tibet black pigs over 30kg of complete feed. It is prepared from feed materials with a total water content of 20% at a temperature of 35°C, sealed and fermented for 4 days; wherein, the feed materials contain the following parts by weight Ingredients: 0.15 parts of Saccharomyces cerevisiae, 0.05 parts of Lactobacillus acidophilus, 0.05 parts of Bacillus subtilis, 180 parts of soybean meal, 180 parts of soybean hull, 250 parts of wheat bran, 180 parts of rapeseed meal, 180 parts of rice bran meal. Feed ingredients generally contain 12-15% water, and the part with insufficient water content can be added to 20%.
[0030] In the biological feed after fermentation, the number of viable bacteria ≥2.0×10 9 Pieces / g, organic acid ≥2.0%.
[0031] The soybean meal, soybean hulls, bran, rapeseed meal, and rice bran meal are crushed before being fermented, and the crushed sieve pieces are all 1.0×1.0 mm.
