Problems solved by technology

Sweet potato slag is the residue produced during the processing of sweet potato starch. It has high water content, many bacteria, easy to spoilage, low protein content and high fiber content in dry matter, and is usually discarded as waste or used as low-quality feed raw materials Simple utilization will cause waste of resources and environmental pollution. How to develop and utilize sweet potato residue resources has become an urgent problem to be solved in my country's starch industry

Embodiment 1

[0028] The following raw and auxiliary materials and reagents were used by weight: 160 grams of sweet potato dregs, 40 grams of wheat bran, 3 grams of urea, 3 grams of ammonium sulfate, 1.2 grams of potassium dihydrogen phosphate, and 1 gram of magnesium sulfate.

[0029] Preparation method: After weighing the above-mentioned raw materials and reagents, put them into a pulverizer to crush them, and then put them into a mixer to mix evenly to make a fermentation substrate. The liquid is a combined fermentation strain bacterial liquid, wherein the bacterial liquid concentrations of Bacillus subtilis, Saccharomyces spp., Trichoderma viride and Lactobacillus plantarum are all 1×10 6 Individual / ml, the combined fermentation strain bacterial liquid is formed by mixing the bacterial liquids of Bacillus subtilis, Saccharomyces spp., Trichoderma viride and Lactobacillus plantarum according to the volume ratio of 2:2:3:1, fermented The substrate and the combined fermentation strain liqu...

Embodiment 2

[0031] The following raw and auxiliary materials and reagents are adopted by weight: 160 grams of sweet potato dregs, 40 grams of wheat bran, 3 grams of urea, 1.5 grams of ammonium sulfate, 1.2 grams of potassium dihydrogen phosphate, and 1 gram of magnesium sulfate.

[0032] Preparation method: The difference from Example 1 is that the combined fermentation strain bacterial liquid is composed of the bacterial liquids of Bacillus subtilis, Saccharomyces spp., Trichoderma viride and Lactobacillus plantarum in a volume ratio of 1:1:1:1 It is formed by mixing in proportion; the fermentation substrate and the combined fermentation strain liquid are uniformly mixed in a weight ratio of 1:1.2.

Embodiment 3

[0034]The following raw and auxiliary materials and reagents are used by weight: 150 grams of sweet potato dregs, 50 grams of wheat bran, 3 grams of urea, 3 grams of ammonium sulfate, 1.2 grams of potassium dihydrogen phosphate, and 1 gram of magnesium sulfate.

[0035] Preparation method: The difference from Example 1 is that the combined fermentation strain bacterial liquid is composed of the bacterial liquids of Bacillus subtilis, Saccharomyces spp., Trichoderma viride and Lactobacillus plantarum according to the volume ratio of 1:2:2:2 It is formed by mixing in proportion; the fermentation substrate and the combined fermentation strain liquid are uniformly mixed in a weight ratio of 1:1.1.

Abstract

The invention discloses a sweet potato residue fermentation feed and a preparation method thereof,and relate to the field of preparing animal feed from plant materials. The fermentation feed is prepared by using 75-80% of sweet potato residue and 20-25% of wheat bran as a raw material and an auxiliary material, and adding a reagent based on the raw material; mixing 0.75-1.5% of urea, 0.75-1.5% of ammonium sulfate, 0.5-0.7% of mono potassium phosphate and 0.4-0.6% of magnesium sulfate to obtain a fermentation substrate; mixing bacillus subtilis, saccharomycopsis fibuligera, trichoderma viride and bacterium solution of lactobacillus plantarum to prepare a bacteria liquid of combined fermentation strains through aerobic fermentation. The weight ratio of the fermentation substrate to the bacteria liquid of the combined fermentation strains is 1:1-1.2; the volume ratio of four bacteria liquids is 1-3:1-3:1-3:1-3. The method can increase the amount of true protein of the fermentation substrate, reduce the amount of coarse fibers, improve the feed palatability and digestibility and utilization, and fully improve the nutritional value of sweet potato residue, thereby having both economic benefits and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of animal feed produced from plant materials. Background technique [0002] my country is the largest sweet potato producer in the world. The perennial sweet potato planting area is 75-80 million mu, accounting for 4.2% of my country's total cultivated land, accounting for about 60% of the world's planting area, and its output accounts for about 80% of the world's total. Sweet potato slag is the residue produced during the processing of sweet potato starch. It has high water content, many bacteria, easy to spoilage, low protein content and high fiber content in dry matter, and is usually discarded as waste or used as low-quality feed raw materials Simple utilization will result in resource waste and environmental pollution. How to develop and utilize sweet potato residue resources has become an urgent problem to be solved in my country's starch industry. Using biotechnology, especially microbial fermentation...
