Bifidobacterium bifidus feed additive

Abstract

The invention discloses a bifidobacterium bifidus feed additive. The bifidobacterium bifidus feed additive is characterized by being prepared by uniformly mixing bifidobacterium bifidus, sea-buckthornfreeze-dried powder, roxburgh rose freeze-dried powder, wintercherry freeze-dried powder, blackcurrant freeze-dried powder and cactus freeze-dried powder, then adding the balance of carbonized eggshell powder, then uniformly mixing, compounding and packing. Per 1000g of the feed additive is prepared from 1000-12000 billions of bifidobacterium bifidus, 5-50g of sea-buckthorn freeze-dried powder, 5-50g of roxburgh rose freeze-dried powder, 3-30g of wintercherry freeze-dried powder, 3-30g of blackcurrant freeze-dried powder, 50-150g of cactus freeze-dried powder and the balance of carbonized eggshell powder. According to the bifidobacterium bifidus feed additive, the living bacteria are clear; application and quantification selection of the user are facilitated; the sea-buckthorn freeze-dried powder, the roxburgh rose freeze-dried powder, the wintercherry freeze-dried powder, the blackcurrant freeze-dried powder, the cactus freeze-dried powder and the carbonized eggshell powder are usedas base materials of the additive; the stability, the trophism and the adsorptivity of the bacteria in the additive can be improved; meanwhile, the nutrition value of the additive is increased; the bifidobacterium bifidus feed additive is capable of accelerating the metabolism of animals, improving disease resistance of organisms, accelerating the growth of the animals and finally increasing the economic benefit of the breeding industry.

Description

technical field [0001] The invention belongs to the field of feed additives and relates to a Bifidobacterium microbial feed additive for breeding animals. Specifically relates to a bifidobacterium bifidobacterium feed additive. Background technique [0002] Bifidobacterium was first isolated by Tissier in 1899 and is a Gram-positive bacillus. There are more than 30 known species of Bifidobacterium. Compared with lactic acid bacteria, bifidobacteria have the following disadvantages: (1) strict and complex requirements for nutrients, the medium must contain auxin or yeast extract to grow; (2) anaerobic conditions are more stringent; (3) at pH The survival time is short in low environment. Bifidobacteria can ferment sugars to produce a large amount of acetic acid and lactic acid, thereby inhibiting the growth and reproduction of potentially pathogenic Enterobacteriaceae and gradually achieving the balance of intestinal microorganisms. When the animal breeding environment, f...

Compared with lactic acid bacteria, bifidobacteria have the following disadvantages: (1) strict and complex requirements for nutrients, the medium must contain auxin or yeast extract to grow; (2) anaerobic conditions are more stringent; (3) at pH Short survival time in low environment

[0005] In order to keep the pH value in the stomach of the animals relatively constant, so that the fed food can continue to achieve the effect of acidification after entering the small intestine, acidulants such as citric acid, lactic acid, hydrochloric acid, and fumaric acid are often used in the product at the same time, but these acidulants Not only does it directly cause excessive acidity to the part of the microorganisms contained in the additive, which affects the survival of the bacteria, but at the same time, these acidified substances have no nutritional value for direct use of the farmed animals. At the same time, they are harmful to the gastrointestinal The props are very irritating, and its compatible application is not ideal
