Bifidobacterium feed additive

Abstract

The invention discloses a bifidobacterium feed additive. The bifidobacterium feed additive is characterized by uniformly mixing bifidobacterium, fructus hippophae rhamnoides freeze-dried powder, fructus rosa roxbunghii freeze-dried powder, fructus physali alkekengi.L freeze-dried powder, fructus ribes nigri freeze-dried powder, herba opuntiae strictae freeze-dried powder, adding the balance of carbonized egg shell powder, compounding and packaging as follows: every 1000 g of feed additive is added with 1000 to 12000 billions of bifidobacterium, 5-50 g of fructus hippophae rhamnoides freeze-dried powder, 5-50 g of fructus rosa roxbunghii freeze-dried powder, 3-30 g of fructus physali alkekengi.L freeze-dried powder, 3-30 g of fructus ribes nigri freeze-dried powder and 50-150 g of herba opuntiae strictae freeze-dried powder, and the balance of carbonized egg shell powder. The bifidobacterium feed additive contains definite viable organisms, is beneficial for user application and quantized selection, utilizes the fructus hippophae rhamnoides freeze-dried powder, the fructus rosa roxbunghii freeze-dried powder, the fructus physali alkekengi.L freeze-dried powder, the fructus ribes nigri freeze-dried powder, the herba opuntiae strictae freeze-dried powder and the carbonized egg shell powder as substrates of the additive, can improve stability, trophism and adsorption of thalli contained in the additive, improves the nutrient value of the product, promotes metabolism of animals, improves disease resistances of the organisms, promotes growth of the animals, and finally improves economic benefits of the livestock breeding.

Description

technical field [0001] The invention belongs to the field of feed additives and relates to a single-type bifidobacterium feed additive for breeding animals. Specifically relates to an animal 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, feed, d...

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
