Abstract
The invention discloses an efficient feed compound probiotics preparation and a preparation method of the probiotics preparation, belonging to the field of biotechnology. The compound probiotics preparation is prepared by mixing the respectively fermented bacillus licheniformis, streptococcus thermophilus, and saccharomyces cerevisiae hansen according to a ratio, and the number of effective microorganisms reaches 8-120*108CFU/mL. The compound probiotics preparation is scientific and reasonable in strain compatibility, can kill or inhibit pathogenic bacteria in an animal body, promotes feed digestion and absorption, and can greatly reduce the use of antibiotic in the feed.
Description
Technical field
The present invention relates to a kind of feed addictive, relate in particular to a kind of efficient compound probiotic agent of forming by complex microorganism.
Background technology
In modern animal husbandry, add antibiotic in the feed and start from the fifties, to disease preventing and treating, promote growth, save feed, improve the culturing economic benefit and play an important role.But, along with the feed midium or long term is added antibiotic and chemical synthetic drug in large quantities, pathogenic microorganism generation drug resistance in the animal body has appearred in breeding production, and effect reduces, and production cost strengthens; Produce pharmacological dependence in the animal body, the immunity function of self suppresses, and immunity and premunition reduce; Beneficial bacterium is suppressed in the animal body, and flora imbalance forms autogenous infection; Animal product and excreta medicament residue jeopardize health; The diffusion of drug-fast bacteria causes significant problems such as public safety in the animal body, needs to be resolved hurrily.
Therefore, from the eighties beginning, relevant probio is in the application study fast development of aquaculture.At present, probio research both at home and abroad relates to a kind surplus the row beneficial bacterium 80." the feed addictive kind catalogue (2006) " of China's promulgation granted totally 16 of use beneficial bacteriums.The bacillus preparation that promote the domestic market has cereobiogen, whole intestines life, antibacterial life, newborn Kang Sheng etc.; Lactobacillus preparation is based on genus lactubacillus and Bifidobacterium.Probio is as a kind of bioactive additive of new type natural, and is nontoxic, the no resistance to the action of a drug, and noresidue, and have enhancing immunity, and promote growth, improve the effect of efficiency of feed utilization, substitute antibiotic and use in the breeding production.
At present, probiotics preparation is applied to breeding production, but remains aspect technology of preparing in problems: (1) product standard disunity, and manufacturing enterprise sets up standard voluntarily, lacks scientific basis, and probio too high levels or low excessively influences result of use; (2) produce the bacterial classification source and fail to understand that most of enterprises produce and mutually transfer with bacterial classification, do not pass through isolation and selection, spawn degeneration is serious, and physiologically active reduces; (3) the bacterial classification compatibility lacks scientific basis, single bacterial strain, and two bacterial strains, even the random proportioning of many bacterial strains can not illustrate the reasonability of compatibility between bacterial strain not reach the bacterial strain merit that complementary by reasonable compatibility, concertedness is poor; (4) production technology confusion can not be cultivated by the different physiological property differences of bacterial classification, and many manufacturing enterprises adopt many bacterial classifications Mixed culture, and without fermentation tank, very the person adopts and heaps fermentation, causes the probio growth few, and assorted flora is given birth to.
Summary of the invention
In order to solve the not problem of science, synergy difference of compatibility that above probiotics preparation exists, the invention provides the good efficient composite probiotics preparations of scientific and reasonable, the mutual synergistic action effect of a kind of compatibility.
Another object of the present invention provides the preparation method of described efficient composite probiotics preparations.
