Description

A kind of composite microorganism type forage additives and application thereof improving fresh-water fishes growth rate
Technical field
The invention belongs to aquatic feeds technical field, relate to feed addictive, be specifically related to a kind of composite microorganism type forage additives and the application thereof that improve fresh-water fishes growth rate.
Background technology
Animal raw materials day by day in short supply, makes the development of aquatic feeds face significant challenge.At present, vegetable raw material is being widely used in aquatic feeds.But freshwater fish, to vegetable raw material digestibility and utilization ability, as freshwater fish lacks phytase, can not make full use of phytate phosphorus etc.; Lacking endogenous non-starch polysaccharide enzyme causes alimentary canal chymeviscosity to increase, and have impact on digesting and assimilating of nutriment.Research shows, the complex enzymes such as usable fibers element enzyme, zytase, phytase carry out enzymolysis, stimulate endogenous digestive ferment to secrete, improve the digestibility of vegetable protein, starch, promote the growth of aquatic livestock.Containing acid protease, cellulase, pectase etc. in aspergillus niger solid fermentation complex enzyme, enzyme system enriches, low production cost is aided with commercial neutral proteinase, cellulase, zytase and phytase again, the deficiency of the digested enzyme of fish digestive tube can be supplemented, and then sufficient enzymolysis is carried out to feed, improve efficiency of feed utilization.By adding bacillus subtilis and bacillus cereus, its breeding in enteron aisle can change fish gastrointestinal micro-flora, improves micro-ecological environment in body, makes beneficial bacterium occupy advantage, suppress the growth and breeding of pathogenic microorganism, reduce and prevent the generation of enterogastric diseases.
Summary of the invention
The present invention is directed to the situation of fresh-water fishes to forage plant property raw material digestion power difference, provide a kind of composite microorganism type forage additives and the application thereof that improve fresh-water fishes growth rate, utilize feed addictive of the present invention can significantly improve the growth rate of fresh-water fishes.
For achieving the above object, the present invention adopts following technical proposals to be achieved:
Improve a composite microorganism type forage additives for fresh-water fishes growth rate, described composite microorganism type forage additives comprises following component:
