The application provides a pediococcus acidilactici M4 for low-moisture fermented feed and an application thereof, and belongs to the field of microbial application and feed technology. The application uses the pediococcus acidilactici M4 to prepare fermented total mixed ration. The bacteria have the characteristics of high osmosis and fast acid production, and can reduce the pH value of the fermentation system in a short time; have strong broad-spectrum bacteriostatic effect on escherichia coli, chicken white dysentery salmonella and staphylococcus aureus; and perfectly adapt to the fermentation of low-moisture total mixed ration. The strain is used as the fermentation strain of low-moisture total mixed ration, can significantly reduce the content of acid detergent fiber and neutral detergent fiber, improve the crude protein level, and then improve the digestibility of the daily ration, increase the content of probiotics such as lactic acid bacteria and yeast in the daily ration, reduce the content of pathogenic bacteria such as escherichia coli in the daily ration, and also can improve the content of volatile fatty acid in the daily ration, improve the quality of the daily ration, and improve the feeding value of the daily ration.

The application discloses a preparation method of bio-modified wheat bran containing xylo-oligosaccharide, and comprises the following steps: fermenting wheat bran by using mixed strains and composite enzymes; wherein the mixed strains comprise lactic acid bacteria, Saccharomyces cerevisiae and Bacillus licheniformis; and the composite enzymes comprise cellulase and xylanase. The preparation method provided by the application effectively reduces the contents of crude fiber and neutral detergent fiber in the wheat bran, increases the contents of crude protein and xylo-oligosaccharide in the fermented wheat bran, which are beneficial to the growth and development of animals, and improves the nutritional value of the wheat bran, so that the proportion of the wheat bran in feed application can be increased, and the addition amount of corn and soybean meal can be reduced.

The application discloses a compound microbial agent for improving fiber utilization of broilers and application thereof, and belongs to the technical field of microorganisms. The compound microbial agent is compounded by Lactobacillus casei R7-6 and Lactobacillus rhamnosus R5-8 at a volume ratio of 1:0.5-2. The two known strains are compounded for the first time, and it is found that the compounded strains have a synergistic effect within the range of 1:0.5-2, and the effect is significantly reduced beyond the range. The compound microbial agent has selective fermentation characteristics for different fiber source substrates, and the fermentation effect of the compound microbial agent on purple elephant grass and Guimin elephant grass is significantly better than that on alfalfa and Gegen. After fermentation, the content of crude protein is increased, and the content of neutral detergent fiber is reduced. When the compound microbial agent is used for feeding the purple elephant grass or the Guimin elephant grass, the daily average weight gain of broilers is increased, the feed conversion ratio is reduced, and the abdominal fat rate is reduced. The application provides an efficient microbial solution for high-value utilization of agricultural by-products such as purple elephant grass, Guimin elephant grass and other fibers.

The present application provides a kind of animal feed with bamboo instead of grain.The feed includes 15%-22% of crude protein, 12%-18% of crude fiber, 0.5%-1.5% of bamboo leaf flavonoids, 0.03%-0.10% of gamma-aminobutyric acid, 2%-5% of lactic acid, the degradation rate of neutral detergent fiber is greater than or equal to 40%, and does not contain exogenous added antibiotics.The preparation method of the feed includes mechanical-thermal two-stage pretreatment, enzymolysis, solid two-stage fermentation, directional metabolic regulation, low-temperature drying and compounding.The present application significantly improves the degradation rate of bamboo fiber and the content of functional ingredients through mechanical-thermal synergistic pretreatment and directional metabolic regulation, and realizes the high-value utilization of bamboo processing residues.

The present application relates to the field of plant genetic engineering technology, and particularly relates to the application of algal NySAT2 gene in regulating alfalfa crude protein and washing fiber. The present application uses gene synthesis and codon optimization technology to obtain the sequence of the coding region of the codon-optimized NySAT2 gene, constructs an algal NySAT2 gene overexpression vector, introduces the target gene into the alfalfa genome through the Agrobacterium rhizogenes-mediated genetic transformation method, and obtains the transgenic plant using the genetic transformation system. Through molecular identification and phenotype analysis, it is found that the alfalfa plants overexpressing the NySAT2 gene have a significantly increased crude protein content compared with the wild-type alfalfa plants, while the contents of acid detergent fiber and neutral detergent fiber are significantly reduced, effectively improving the forage quality and feeding value of alfalfa.
