The present application relates to the technical field of feed, especially to a growth-promoting feed for fattening pigs and a preparation method thereof, which comprises the following raw materials in parts by weight: corn, wheat bran, soybean meal, rapeseed meal, fish meal, modified hydrotalcite, compound enzyme preparation, probiotic preparation, calcium hydrogen phosphate, stone powder, salt, zinc oxide, copper sulfate pentahydrate, soybean oil, choline chloride, mildew inhibitor and antioxidant. The modified hydrotalcite, compound enzyme preparation and probiotic preparation are used in combination, which can significantly improve the growth performance of fattening pigs, reduce the diarrhea rate, improve the nutrient digestibility and improve the serum metabolic indicators.

This invention discloses a porcine lactobacillus mucosa HEB-FEC-LM-001 and its applications, belonging to the field of feed additive technology. The porcine lactobacillus mucosa HEB-FEC-LM-001 provided by this invention is a Gram-positive bacterium with a milky-white, raised colony appearance, clear edges, and a smooth surface. It was deposited at the China Center for Type Culture Collection on October 21, 2025, with accession number CCTCC NO:M 20252272. A synbiotic is prepared by combining porcine lactobacillus mucosa HEB-FEC-LM-001 with raffinose. When fed as a feed additive to weaned piglets, it can significantly improve the piglets' intestinal health, apparent nutrient digestibility, and immune function, significantly reduce the diarrhea rate, and improve the growth performance of weaned piglets. Therefore, it has broad application prospects as a feed additive for weaned piglets.

The present application belongs to the technical field of animal feed preparation, and particularly relates to a straw-based single-cell protein feed as well as a preparation method and application thereof. In the present application, steam explosion is combined with alkali-oxygen pretreatment to break the straw lignin barrier and improve the polysaccharide degradation efficiency; a mutant of Trichoderma reesei is obtained by using atmospheric and room temperature plasma (ARTP) mutagenesis, and is used for solid-state fermentation in combination with bacteria and enzymes to efficiently convert fermentable sugar and greatly improve the crude protein content of the product. The process abandons traditional high-pollution chemical treatment, is water-saving and environmentally friendly, uses cheap and easily available raw materials, and is easy to scale up. The present application can increase the crude protein content of straw from 4% to 6% to 10% to 15%, and the upgrading effect is remarkable. The feed obtained by the present application can replace 20% to 30% of the crude protein raw materials in the feed, improve the growth performance and nutrient digestibility of animals, and realize the resource-based high-value utilization of straw.

This invention discloses a bacterial residue compound fermentation agent and its preparation method, belonging to the field of biotechnology. The fermentation agent is composed of *Bacillus subtilis*, *Lactobacillus plantarum*, and *Candida utilis* in a specific live bacteria ratio, and is synergistically formulated with cellulase, xylanase, laccase, and peroxidase. The total bacterial dry matter accounts for 35%–45%, and the compound enzyme system accounts for 55%–65%. The preparation method includes: step S1, bacterial culture and powder preparation; step S2, bacterial powder mixing and compounding; step S3, enzyme powder preparation; and step S4, mixing and sieving. This invention achieves efficient degradation of lignocellulose, enrichment of crude protein, and efficient chemical degradation of aflatoxin B1, zearalenone, and vomitoxin through dynamic pH control and metabolic flux distribution. When used for corn cob treatment, this fermentation agent significantly improves the production performance, nutrient digestibility, and antioxidant and immune functions of beef cattle.
