Problems solved by technology

[0009] 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

Embodiment 1

[0055] Preparation of seabuckthorn freeze-dried powder, prickly pear freeze-dried powder, Physalis freeze-dried powder, blackcurrant freeze-dried powder, cactus freeze-dried powder:

[0056] 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

[0058] Preparation of carbonized eggshell powder:

[0059] 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

[0061] Preparation of carbonized eggshell powder:

[0062] 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 lactic streptococci feed additive. The lactic streptococci feed additive is characterized by being prepared by uniformly mixing lactic streptococci, sea-buckthorn freeze-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 3000-15000 billions of lactic streptococci, 5-50g of sea-buckthorn freeze-dried powder, 5-50g of roxburghrose 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 lactic streptococci 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 used as base materials ofthe 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 lactic streptococci 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 probiotic feed additive for breeding animals. Specifically relates to a feed additive for Streptococcus lactis. Background technique [0002] Lactic acid bacteria (LAB) There are more than 100 known species of lactic acid bacteria. The application history of lactic acid bacteria is very long, such as the production and production of dairy products, pickles, silage, etc. There are a large number of lactic acid bacteria in the intestines of humans and animals. Lactic acid bacteria preparation is a preparation containing live lactic acid bacteria called Lactobacillus. Lactic acid bacteria grow and develop in the intestinal tract, decompose sugars to generate lactic acid and form an acidic environment, thereby inhibiting the proliferation of harmful bacteria in the intestinal tract, and preventing toxin production and disease-causing. The strains for preparing the lactic acid bacteri...
