A kind of animal feed additive and preparation method thereof

Abstract

The invention discloses an animal feed additive and a preparation method thereof. The additive comprises 20 g of codonopsis pilosula, 20 g of astragali radix, 10 g of malt, 10 g of fructus crataegi(stir-fried), 250 g of bean pulp, 250 g of cottonseed meal, 250 g of rapeseed meal, 100 g of sweet pepper pulp and 90 g of chrysanthemum powder. The preparation method of the additive comprises the following steps: firstly, conducting primary fermentation on the codonopsis pilosula, the astragali radix, the malt and the fructus crataegi(stir-fried) through using lactobacillus bulgaricus, wherein liquid fermentation is adopted in the primary fermentation, and the bacterium-inoculating amount is 20%; secondly, conducting secondary fermentation on the product subjected to the primary fermentation with 250 g of bean pulp, 250 g of cottonseed meal, 250 g of rapeseed meal, 100 g of sweet pepper pulp and 90 g of chrysanthemum powder through using saccharomycetes, so that a finished additive is obtained. According to the invention, effective ingredients in the traditional Chinese herbal medicines can be fully released during the primary fermentation; cellulose, protein and carbohydrates in the traditional Chinese herbal medicines and enriched plant materials can be resolved and converted during the secondary fermentation, as a result, rich organic acid and amino acid are produced, the nutrient content is further enriched, and the mouthfeel of the animal feed is better.

Description

technical field [0001] The invention relates to the field of animal feed additives, in particular to an animal feed additive and a preparation method thereof. Background technique [0002] Chinese herbal medicine contains a variety of chemical components. It is a natural combinatorial chemical library, rich in protein, amino acids, vitamins, various trace elements, and a large number of organic acids, enzymes, alkaloids, polysaccharides, glycosides, tannins, etc. and growth-promoting active substances, but due to the obstruction of plant cell walls, a large amount of active ingredients are difficult to release. Microorganisms can produce a large amount of digestive enzymes during the growth process. Utilizing the characteristics of microorganisms and using fermentation can effectively improve the efficacy of medicines and achieve the effect of health care. [0003] At present, the fermentation of Chinese herbal medicines commonly used in the market is one-time fermentation,...
