Bifidobacterium longum feed additive

Abstract

The invention relates to a bifidobacterium longum feed additive. The bifidobacterium longum feed additive is characterized by being prepared by uniformly mixing, compositing and packaging bifidobacterium longum, hippophae rhamnoides freeze-dried powder, roxburgh rose freeze-dried powder, wintercherry freeze-dried powder, blackcurrant freeze-dried powder, and cactus freeze-dried powder as well as the balance of fermented eggshell powder, wherein in every 1,000g of feed additive, 1,000 billion to 12,000 billion bifidobacterium longum, 5 to 50 g of hippophae rhamnoides freeze-dried powder, 5 to 50 g of roxburgh rose freeze-dried powder, 3 to 30 g of wintercherry freeze-dried powder, 3 to 30 g of blackcurrant freeze-dried powder, 50 to 150 g of cactus freeze-dried powder and the balance of fermented eggshell powder are added. The bifidobacterium longum feed additive is a single feed additive, is definite in viable count, and favorable for the user to have clear application and quantitativeselection. The freeze-dried powder of hippophae rhamnoides, roxburgh rose, wintercherry, blackcurrant, cactus and the fermented eggshell powder are used as a matrix of the additive, so that not onlycan the nutritional value of the bifidobacterium longum additive be increased, but also the metabolism of the animal can be promoted at the same time, the disease resistance of the body can be improved, the growth of the animal can be promoted, and finally the economic benefit of the breeding industry can be increased.

Description

technical field [0001] The invention belongs to the field of feed additives and relates to a bifidobacterium feed additive for breeding animals. Specifically relates to a bifidobacterium longum 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, feed, disease, abuse...

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
