Abstract
The invention relates to a method for preparing a microbial feed additive. Feather meal, mannitol, glucose, sodium citrate, sodium chloride and the like are taken as raw materials, and inoculated with Bacullus subtilis YYW-1 with the number of CGMCC NO.2396 to prepare the microbial feed additive by submerged fermentation and spin flash drying technology. The active ingredients of the microbial feed additive are the Bacullus subtilis and cultures thereof, and the cultures contain metabolites such as keratinase capable of efficiently degrading feather. The product can be used in the breeding industry and the feed industry, and has the advantages of improving intestinal flora, improving digestion and absorption capacity of animals and the feed conversion and utilization rate, particularly promoting the digestion, absorption and utilization of protein materials such as the feather meal, and reducing cost.
Description
Technical field
The present invention relates to a kind of additive for microbe feedstuff and preparation method thereof, belong to agricultural biological technical field.
Background technology
Additive for microbe feedstuff is a kind of safe, green novel fodder additive; Have and promote growth, disease resistance, improve product quality, be of value to effect such as environment, be applied to modern animal husbandry as production safety livestock products important safeguards technique and Antibiotic Additive substitute products.
China has been livestock products production and big export country at present, but in recent years livestock products particularly the outlet of meat is limited repeatedly, mainly be exactly reasons such as antibiotic and medicament residue, epidemic prevention and control system imperfection.Use antibiotic to make the history of growth promoter and existing over half a century of disease preventing and treating in its feeding; Over nearly 30 years; The prolonged application antibiotic is caused the generation of animal autogenous infection or suprainfection, antibody-resistant bacterium; Livestock and poultry cellular immunity, humoral immune function are descended and antibiotic residual in livestock products meat, egg, milk, direct threats side effect such as human body health has had deep understanding.National governments pay close attention, and many developed countries promulgate a decree, and limit or ban use of antibiotic as feed addictive.European Union's legislation forbids that from January 1st, 2006 all antibiotic use as feed addictive.Meanwhile, to overcoming all drawbacks of antibiotic, nontoxic, have no side effect, the microbe additive of noresidue paid attention to day by day, some developed countries have realized industrialization.
China is later relatively to the research and the industrialization development of additive for microbe feedstuff; Begin animal microecology research the eighties in 20th century; The end of the nineties, additive for microbe feedstuff got into industrialization development and application, and aspects such as product yield, quality, industrialization level are compared with international most advanced level and also had big gap at present.Main cause is owing to lack efficient bacterial strain and corresponding production technology preparation method.CN1682599 (200410031196.7) discloses a kind of additive for microbe feedstuff; Specifically relate to a kind of additive for microbe feedstuff of being made up of multiple beneficial microorganism and its metabolite (like protease, lipase, amylase, cellulase etc.), this additive for microbe feedstuff is that bacillus subtilis, Bacillus cercus, Bacillus acidi lactici and S. cervisiae are carried out the zymotic fluid of deep liquid high density fermentation cultivation or the mixture of dry powder respectively.CN 101638627A (200910034843) discloses a bacillus subtilis and the application in biology feed additive thereof, and related bacillus subtilis HF-A1 (CGMCCNo3241) obtains near screening in the content of mucous membrane from the intestines and stomach that pick up from healthy sucking pig; This feed addictive contains bacillus subtilis (HF-A1), lactic acid bacteria and saccharomyces cerevisiae.CN1934989 (200610037429.3) discloses a kind of additive for microbe feedstuff, is to contain bacterial population 5.0～6.0 * 10 for bacterial classification through what preparation processes such as purebred enlarged culture, liquid fermentation and culture, the cultivation of solid second order fermentation obtained with Trichoderma, Aspergillus, actinomyces, bacillus, S. cervisiae Li 1012 (Saccharomyces cerevisiae Li1012)
7Cfu/g, yeast count 4.0～5.0 * 10
4Cfu/g, fungi count 2.0～3.0 * 10
4The additive of cfu/g, the water content of additive≤10%; Product quality is high, sneaks into the good stability behind the feed.The bacillus that utilizes that above patent document has produces enzyme performance; Like protease, lipase etc.; Or utilize the composite production feed addictive of bacillus subtilis and other bacterium; Fermented and cultured based raw material and drying mode all are extensive uses in conventional the production, are not the preparation methods to specific function bacterial classification (as decomposing feather keratin matter function) and special drying mode (both having guaranteed that high number of viable also can keep metabolite activity).
