Description
Technical field
The present invention relates to a kind of fermented concentrated feed technical fields, more particularly to a boar fermented concentrated feed and its system
Preparation Method.
Background technique
Since antibiotic is found, just largely used by the mankind always, antibiotic improve breeding performonce fo animals and
There is positive effect in terms of disease resistance, but large dosage is actually a double-edged sword using antibiotic, is killing body pathogenic bacteria
While, the colony balance in animal intestinal tract is also destroyed, intestine microenvironment disorder is made, drug Resistance of Pathogenic Microorganism from Surface increases
By force, or even the residual of antibiotic in meat products is caused, directly injures mankind itself's health.With mentioning for people's living standard
Height, food-safe problem pay attention to day by day, strict control and the use for reducing antibiotic are inevitable.From in January, 2006, Europe
Alliance has completely forbidden adds antibiotic in animal feed.It in recent years, is biological feed fermentation agent bacterium with microorganism, complex enzyme
Kind, microbial bacteria body protein, bioactive micro peptide amino acid, microbial activity probiotics, compound is converted by feedstuff
Enzyme preparation is integrated biological fermentation feed and is gradually received by industry, has become one of important substitute of antibiotic.
Biological feedstuff is proved to that raw material nutritive value can be improved, mycotoxin of degrading, by vegetalitas, animality and mineral
Property substance in anti-nutritional factors decompose or conversion, generate the digestion that can more be searched for food by livestock, absorb nutrient is higher and nonhazardous
The feedstuff of effect.However, product of microorganism fermented forage is very different at present, application effect feedback is ideal not to the utmost, mainly
The reason is that raw material proportioning is improper, strain and enzyme preparation selection collocation are unreasonable, zymotechnique is unstable, viable bacteria is colonized in enteron aisle
Ability is poor, finished product index is unqualified etc..
