4results about How to "Improve digestive enzyme activity" patented technology

The application discloses a kind of fermented feed fermented by three strains of probiotics of Bacillus YA ( Bacillus sp ), yeast Y ( Saccharomyces cerevisiae ) and capsular red bacteria R3 ( Rhodobacter capsulatus ), and preparation method and application in aquaculture thereof, and viable count is not less than 1×10 7 CFU / g.The fermented feed is replaced ordinary feed according to certain proportion, and feeding result shows that aquaculture water quality is significantly improved after adding fermented feed, and fish growth performance, digestive enzyme activity, immunity, and muscle quality are also obviously improved.Using the feed in suitable range can shorten growth cycle, reduce cost, improve aquaculture environment, reduce antibiotic use, and improve muscle quality of farmed animals, with good economic and ecological benefits, simple fermentation process, low cost, and suitable for industrial large-scale production.

The application provides a composition for improving intestinal digestive enzyme activity and application thereof, and belongs to the technical field of animal medicine. The composition is composed of double-kidney polysaccharide, ginsenoside Rb1 and ginsenoside Rg1. In the composition, the mass ratio of the double-kidney polysaccharide, the ginsenoside Rb1 and the ginsenoside Rg1 is 90:5:5 or 95:2.5:2.5, preferably 90:5:5, and the intestinal digestive enzyme is specifically duodenal trypsin and amylase. Experimental results show that the composition can significantly synergistically improve the activities of the duodenal trypsin and amylase of laying hens, improve the feed utilization rate, thereby improve the egg production rate, improve the egg weight and the eggshell strength, and effectively improve the breeding benefit of the laying hens.

This application discloses a marine fish feed and its preparation process, relating to the field of aquaculture feed technology. It includes 73.2-82.8 parts by weight of protein components, 10.8-13.2 parts by weight of energy components, 4.5-5.6 parts by weight of fortifying components, 2.5-3.5 parts by weight of functional additives, and 33.5-40% by weight of a compound bacterial solution. The protein components include 28-32 parts by weight of red fish meal, 40-43 parts by weight of modified compound protein, 4-6 parts by weight of soybean protein concentrate, and 1.2-1.8 parts by weight of compound enzymatically hydrolyzed fish lysate. The modified compound protein is a biparental composite modified protein grafted with hydrophilic and hydrophobic monomers. This application achieves the effect of gentle dissolution of the feed in seawater through the combination of biparental composite modified protein and fortifying components, along with the synergistic effect of specific components, thereby improving nutrient utilization and digestibility, reducing fish meal dependence and aquaculture costs, and promoting fish growth.

This invention relates to the field of microbial fermentation feed technology, and discloses a zero-wastewater feed ingredient production method based on two-stage fermentation. The method includes inoculating *Bacillus bellis* into a liquid fermentation medium for liquid fermentation to obtain a liquid fermentation mixture; centrifuging all of the liquid fermentation mixture to obtain *Bacillus bellis* cells and collecting the supernatant containing the remaining *Bacillus bellis*; adding yeast and lactic acid bacteria to the collected supernatant, then mixing it with solid fermentation raw materials to form a solid-liquid mixture; adding purified water or solid fermentation raw materials to control the fermentation moisture content; and then fermenting the moisture-adjusted solid-liquid mixture under sealed conditions to obtain a pre-fermented mixture as the feed ingredient. This invention avoids wastewater generation during the production process and improves the digestive enzyme activity of the product.
