Problems solved by technology

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, lac

Embodiment 1

[0050] Preparation of seabuckthorn freeze-dried powder, prickly pear freeze-dried powder, Physalis freeze-dried powder, blackcurrant freeze-dried powder, cactus freeze-dried powder:

[0051] Take fresh and mature seabuckthorn, prickly pear, physalis, black currant, cactus, remove impurities such as fruit stems and rotten fruits, rinse with 40°C aqueous solution containing 0.1% citric acid by weight, and rinse for 15 minutes under constant stirring. Rinse in pure water for 3 times, remove and dry the water; put seabuckthorn, prickly pear, physalis, blackcurrant, and cactus into plates and put them into the freezer, and quickly cool down to below -45°C; freeze the frozen seabuckthorn and prickly pear respectively , physalis, blackcurrant, and cactus are moved into the sublimation dryer, the sublimation temperature is controlled at -22--32°C, and the vacuum degree is 120-150Pa, so that the material is dried to moisture 100 mesh to obtain freeze-dried seabuckthorn powder, freeze-dr...

Embodiment 2

[0053] Preparation of carbonized eggshell powder:

[0054] First, clean the eggshell, dry the water, put it in an electric oven, and dry it with hot air at 200°C for 2 hours. Spray the prepared salt solution with a weight ratio of 25% on the coarse shell powder (that is, eggshell powder: 25% salt solution = 1:0.5 ratio), mix while spraying, leave it for 6 hours after mixing, and then mix evenly again , and put it aside for another 6 hours; put the impregnated eggshell powder raw material into a rotary carbonization pot, and rotate it at 420°C for 80 minutes until the raw material turns black completely (the carbonization process is provided with an automatic rotating scraper in the carbonization pot) slices to prevent the raw materials from sticking to the pan and agglomerating during the carbonization process); quickly move the carbonized raw materials to the activation furnace, and pass in CO 2 Gas, drive out the air in it, anaerobic activation at 760°C for 80 minutes (set ...

Embodiment 3

[0056] Preparation of carbonized eggshell powder:

[0057] First, clean the eggshell, dry the water, place it in a far-infrared dryer, and dry it at 300°C for 1 hour. After taking it out and letting it cool, grind it into a 30-mesh coarse powder, and put it on the eggshell at a weight ratio of 1:0.5. Spray the prepared salt solution with a weight ratio of 25% on the coarse powder (that is, eggshell powder: 25% salt solution = 1:0.5 ratio), mix while spraying, leave it for 7 hours after mixing, and then mix evenly again, Place it for another 7 hours; put the impregnated eggshell powder raw material into a rotary carbonization pot, and rotate it at 450°C for 70 minutes until the raw material turns black completely (the carbonization process is equipped with an automatic rotating scraper in the carbonization pot) , to prevent the raw materials from sticking to the pan and agglomerating during the carbonization process); quickly move the carbonized raw materials to the activation ...

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...
