Microorganism feed additive capable of promoting goose liver development and preparation method thereof

Abstract

The invention relates to a method for preparing microbial feed additive used for promoting growth of goose liver. All of the microbial strain is screened out from the animal intestinal tract. The method comprises culturing all the strains on the same culture medium through combined culture, constituting powerful compound microbial community by using mixed sync solid fermentation process, and forming effective enzyme producing ability to make the product has amount of physiologic metabolite such as organized enzyme for analysing cellulose and fructose, peptide, antioxidants, free amino acid, and vitamin. The invention can promote feed digestion and absorption of animal, promote synthesize and utilization of protein, enhance immunologic competence of livestock, fowl and aquatic livestock, and improve feed conversion ratio and production capacity of breed animal. The inventive product has good practicability and pertinency.

Description

technical field [0001] The invention relates to a microbial feed additive for promoting the development of foie gras and a preparation method thereof, which can improve the lecithin synthesis ability in the foie gras and belongs to the technical field of agricultural biological products. Background technique [0002] Goose is mainly fed with green feed and rarely uses drugs. In the minds of consumers, goose meat has gradually been listed as green and safe food. The most edible part of the goose body is foie gras, which contains 40% to 60% fat, and 65% to 68% unsaturated fatty acid, which can reduce the cholesterol content in human blood and inhibit the absorption of other fats. It is extremely beneficial to the human body; every 100 grams of foie gras contains up to 4.5-7 grams of lecithin, which has the effects of softening blood vessels, delaying aging, and preventing and treating cardiovascular and cerebrovascular diseases; It cannot be synthesized in the body. At the sa...

Problems solved by technology

[0003] However, because geese mainly eat fresh green feed, the main component of which is plant fiber, which decomposes very slowly in the animal body, mainly because of the lack of cellulase, hemicellulase and xylase that decompose these fibers, so The breeding period of geese is longer than that of other poultry. The French who are good at gourmet food have come up with a method of intensive feeding for 4 weeks with feed mixed with wheat, corn, fat and salt, so that the geese have "liver lesions". This kind of foie gras is big, plentiful, and pure in color, and is deeply loved by Chinese people. However, it is difficult to rest assured when eating this kind of "disease" foie gras
