Problems solved by technology

However, common tartary buckwheat husks are used as raw materials to produce feed additives that contain anti-nutritional factors, which can cause digestive and absorption dysfunction, disorder, flatulence, and diarrhea in livestock and poultry, especially intestinal damage in young animals, and nutritional diarrhea in young animals. Occurrence, immunocompromised
These anti-nutritional factors can also cause problems such as reduced protein utilization, environmental pollution and increased breeding costs.

Abstract

The invention provides a preparation method for a feed additive with an antioxidation function, which is characterized by comprising the specific steps of: first step: preparing a bacterium fermentation culture medium, inoculating Bacillus natto to the fermentation culture medium and culturing to obtain a seed liquid; second step: cleaning Fagopyrum tataricum shell, sterilizing, adding molasses, calcium carbonate, magnesium sulfate and calcium chloride to be used as a fermentation substrate, inoculating the seed liquid obtained in the first step to the fermentation substrate, placing the fermentation substrate in a fermentation tank and carrying out solid-state fermentation; and third step: drying the fermentation product obtained in the second step, crushing and screening to obtain the feed additive with the antioxidant function. The preparation method provided by the invention performs solid-state fermentation on the Fagopyrum tataricum shell by Bacillus natto, degrades the anti-nutritional factors in the Fagopyrum tataricum shell, improves the contents of rutin, SOD (superoxide dismutase) and soluble dietary fibers, produces a certain amount of organic acids and endows feed a special flavor, improves the oxidation resistance of feed, and improves the resistance and the meat quality of pork pig.

Description

technical field [0001] The invention relates to a preparation method of a feed additive with antioxidant function, and belongs to the technical field of microbial fermentation. Background technique [0002] Free radicals are intermediate metabolites of various biochemical reactions in life activities. They have high chemical activity and are an effective defense system for the body. If they cannot be maintained at a certain level, they will affect the body's life activities. However, if free radicals are produced too much and cannot be removed in time, they will attack life macromolecules and various organelles in the body, causing various damages at the molecular level, cellular level and tissue and organ level, and accelerating the aging process of the body. and induce various diseases. [0003] Antioxidants can scavenge free radicals, prevent the oxidation and rancidity of feed organic matter, especially unsaturated fatty acids, and prevent the oxidation and titer reduct...
