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

[0056] Preparation of seabuckthorn freeze-dried powder, prickly pear freeze-dried powder, Physalis freeze-dried powder, blackcurrant freeze-dried powder, cactus freeze-dried powder:

[0057] 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

[0059] Use the corresponding optimized medium, use liquid culture fermentation equipment to separately culture Candida utilis, Candida tropicalis, brewer's yeast, brewer's yeast and feed yeast, and then use a high-speed centrifuge to separate the bacteria in the fermentation broth, Dry the sludge by vacuum freeze-drying to obtain Candida utilis dry powder with a live bacteria content of 20 billion / g, Candida tropicalis dry powder with a live bacteria content of 20 billion / g, and a live bacteria content of 200 Brewer's yeast dry powder with a live bacteria content of 20 billion / gram, brewer's yeast dry powder with a live bacteria content of 20 billion / gram, and feed yeast dry powder with a live bacteria content of 20 billion / gram.

Embodiment 3

[0061] Preparation of fermented eggshell powder:

[0062] Clean egg shells or one or more mixed egg shells of duck egg shells, goose egg shells, and quail egg shells, dry the water, put them in an oven, and dry them with hot air at 240°C for 1.5 hours, then take them out and let them cool. Grind into 45 mesh powder; weigh 80 kg of eggshell powder, add an appropriate amount of pure water to make the water content of the material 50% (W), then add 20 kg of dry feed yeast powder obtained in Example 2, mix well and put on a plate , placed in a fermentation room, and fermented at a temperature of 31-33°C for 60-72 hours. After the fermentation is over, the fermentation material is adjusted to a temperature of 82°C-92°C and a temperature of 80-90%. Ammonia reaction for 22-28 days, and then the material is dried in an electric oven at no more than 100°C until the moisture content is less than 5% (W), crushed with a universal grinder, and passed through 100 sieves to obtain fermented ...

Abstract

The invention discloses a streptococcus lactis feed additive, per 1000 g of which is characterized by being prepared by the following steps of uniformly mixing 3-15 trillion of streptococcus lactis, 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 50-150g of herba opuntiae strictae freeze-dried powder, then adding the balance of fermented egg shell powder for uniform mixing, and performing composite packaging. The streptococcus lactis feed additive is a single type streptococcus lactis feed additive, is clear and definite in content of living bacteria and facilitates a user to have clear and definite application and quantization selection. For the streptococcus lactis feed additive provided by the invention, by utilizing 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 fermented egg shell powder as a substrate of the additive, the nutritive value of the streptococcus lactis additive is increased, the metabolism of animals is promoted at the same time, the disease resistance of an organism is improved, the growth of the animals is promoted, and the economic benefit of the breeding industry is increased finally.

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...
