The invention belongs to the technical field of livestock and poultry breeding and feed formulas, and particularly relates to feed for improving the meat quality of Songliao black pigs by cooperatively replacing soybean meal with fermented miscellaneous meal and application. The feed is prepared from the following components in parts by mass: 60 to 65 parts of corn, 8 to 12 parts of fermented peanut meal, 6 to 10 parts of fermented sesame seed meal, 3 to 5 parts of soybean meal, 4 to 6 parts of bran, 3 to 5 parts of rice bran, 1 to 2 parts of fish meal, 0.8 to 1.2 parts of stone powder, 0.6 to 0.9 part of calcium hydrogen phosphate, 0.3 to 0.5 part of table salt, 0.2 to 0.4 part of amino acid premix, 0.1 to 0.2 part of vitamin premix, 0.1 to 0.2 part of mineral premix and 0.05 to 0.1 part of compound enzyme preparation, wherein the total mass of the feed is 100 parts. Wherein the mass ratio of the fermented peanut meal to the fermented sesame meal is (1.0-1.5): 1, the proportion of the fermented peanut meal and the fermented sesame meal for synergistically replacing the soybean meal is 70%-85%, the crude protein content of the feed is kept at 16%-18%, and the feed meets the protein requirement of the Songliao black pigs in the fattening period. The feed can meet the growth and metabolism requirements of the Songliao black pigs, and the meat quality is remarkably improved while the breeding cost is reduced.

The invention discloses a compound microbial agent for ensiling miscanthus sinensis and application of the compound microbial agent. The microbial agent is prepared from lactobacillus plantarum LW8 (CGMCC NO.28108) and lactobacillus plantarum K3 (CGMCC NO.34845) according to the viable count ratio of (1.5 to 2.5): 1. The method comprises the following steps: chopping miscanthus sinensis, adjusting the water content, spraying a zymophyte solution prepared from the complex microbial inoculant and brown sugar, and carrying out vacuum sealing and anaerobic fermentation to obtain the miscanthus sinensis silage. The complex microbial inoculant utilizes rapid acid production of LW8 and later-stage stability of K3 to synergistically promote lactic acid fermentation, can rapidly reduce the pH value, significantly inhibit protein degradation (ammoniacal nitrogen / total nitrogen is less than or equal to 0.70%) and reduce the fiber content, and finally obtains miscanthus silage with stable fermentation quality and high nutritional value.

The present application belongs to the field of microbial application and feed processing technology, and discloses a bacillus subtilis, named bacillus subtilis YT1, which is preserved in China Center for Type Culture Collection, located at Wuhan University, No. 299, Bayi Road, Wuchang District, Wuhan City, Hubei Province, with a preservation number of CCTCC NO: M 20242767 and a preservation date of December 10, 2024. The present application also discloses a microbial preparation and the application of the bacillus subtilis or the microbial preparation in the processing of silage. The present application first simultaneously possesses high efficient lignocellulose degradation ability, excellent fermentation promotion characteristics, significant antioxidant activity and good probiotic characteristics in a strain of bacillus subtilis. This characteristic enables a single bacterial agent to achieve multiple goals such as fiber degradation, fermentation promotion, oxidation protection, which traditionally requires multiple compounded bacterial agents, and fundamentally overcomes the problems of poor compatibility between strains, unstable synergistic effect and high application cost of existing compounded additives.

The invention discloses a composite biological fermentation feed and a preparation method thereof, and belongs to the technical field of feed processing.
