Background technology
Spirulina is a class rudimentary plant, belongs to Cyanophyta, Oscillariaceae.The nutritive value of spirulina is very high, contains rich in protein, and is abundanter than the food nutrition on the universal up to 60~70%, also exceeds several times than soybean, beef, egg etc.; The trace element that contains multiple needed by human, calcium, magnesium, sodium, potassium, phosphorus, iodine, selenium, iron, copper, zinc etc., iron deficiency can cause anaemia, scarce zinc can cause depauperation, selenium can activate the DNA repairase, and free radical is caught in the generation of immune stimulatory globulin and antibody, reduce or opposed body in the toxicity of some metal, suppress the carcinogenesis of some carcinogens.Selenium can also prevent mountain sickness; The cell membrane of spirulina is very thin, and thickness only has 40-60 μ m, and is made of mucopolymer, easily is degraded and digests and assimilates; Contain very high acid and gamma-linolenic in the spirulina, have and promote calcium to absorb, improve immunity, prevent metabolic disorder and prevent old and feeble function, acid and gamma-linolenic is the precursor of prostaglandin, under the effect of oxygenase, become prostaglandin, prostaglandin is to reproduction, and cardiovascular, breathing, digestion and nervous system all have effect; Polysaccharide in the spirulina has radiation-resistant function, and by strengthening immunity of organisms.Spirulina polysaccharide can improve the activity of the SOD in the blood plasma in addition, reduces the generation of MDA, and antidotal effect is arranged.Spirulina is a kind of nourishing additive agent of very high-quality, and it all has good nutrition health-care functions to various animals in existing a large amount of experimental results show that.Also have some documents can confirm that it can improve the quality of cultivated animals meat, egg, milk, fur as the poultry feed application facet, but it is never used widely.The main cause that restricts its application is exactly its price.
Because the algae mud water content behind the collection of spirulina is very high, usually all between 93~99%, and will smellyly go bad in several hours under the normal temperature, present method dries spirulina mud to preserve and use with spray-dired method quick high-temp exactly, and present day by day rise along with oil price and electricity price, the dry expense of spirulina powder per ton is all more than 8000 yuan, and the price of high-quality fish meal per ton is like this only, so spirulina powder is difficult to promote at feedstuff industry.
Summary of the invention
The present invention aims to provide a kind of can the solution and expensive spirulina is put into problem in the poultry feed, prepares to be of high nutritive value and the method for the chicken feed that palatability is strong.
This preparation method may further comprise the steps:
1) in container, adds water content at 20%~99.99% spirulina mud;
2) streptococcus acidi lactici fermented solution is joined in the container, it is stirred with spirulina mud, get mixed material, described spirulina mud and streptococcus acidi lactici fermented solution are to be that 1: 0.01~1: 1000 ratio is mixed according to mass percent, and the concentration of lactic acid bacteria is 1 * 10 in the described streptococcus acidi lactici fermented solution
4Cfu/ml~1 * 10
10Cfu/ml;
3) allow the mixed material that stirs in container, ferment;
The mixed material that 4) will ferment carefully mixes with the chicken feed, form to mix the chicken feed, and described mixing chicken feed is to be that 0.01~20% ratio is mixed with the chicken feed according to the spirulina powder mass percent.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation, it is characterized in that, described spirulina mud and streptococcus acidi lactici fermented solution are to be that 1: 0.01~1: 1000 ratio is mixed according to mass percent, and wherein optimal ratio is 1: 0.5~1: 10.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation is characterized in that the concentration of lactic acid bacteria is 1 * 10 in the streptococcus acidi lactici fermented solution
4Cfu/ml~1 * 10
10Cfu/ml, wherein optimal concentration is 1 * 10
6~1 * 10
8Cfu/ml.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation is characterized in that the mixed material that stirs can be preserved more than 7 days in feed reservoir vessel or feed pond.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation, it is characterized in that, described mixed material is that 0.01~20% ratio is mixed with the chicken feed according to the spirulina powder mass percent, and wherein optimal ratio is 0.1%~5%.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation, it is characterized in that, described streptococcus acidi lactici fermented solution, lactic acid bacteria comprises Lactobacillus, streptococcus, Bifidobacterium, genus lactobacillus acidophilus, Mycosphaerella or lactococcus, and this lactic acid bacteria can be a kind of or youngster's kind wherein.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation is characterized in that, can be added into saccharomycete and bacillus at streptococcus acidi lactici fermented solution.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation, it is characterized in that, described lactic acid bacteria can be used separately or youngster plants and compositely uses according to any mass percent, and wherein the bacterial classification of high-quality and ratio are that Lactobacillus casei and the content of streptococcus in streptococcus acidi lactici fermented solution respectively account for 50% mass percent.
Preferably, the described preparation method who mixes the chicken feed through the spirulina mud of microbial fermentation, it is characterized in that, described lactic acid bacteria can be used separately or youngster plants and compositely uses according to any mass percent, and wherein the bacterial classification of high-quality and ratio are that micrococcus, galactococcus and the streptococcus content in streptococcus acidi lactici fermented solution accounts for respectively 50%, 20% and 30% mass percent.
The key of present technique is to screen can carry out microbial fermentation corrosion-resistant lactobacillus, the spirulina mud that the natural antibacterial that relies on lactobacillus to produce the sour sour environment that forms and generation usually carries out high-moisture is anticorrosion, avoided the too high formed cost barrier of dry expense, can commercial application in the poultry feed industry.
Simultaneously, owing to containing a large amount of lactic acid bacterias in the fermentation spirulina mud, these probios can also together enter in the livestock and poultry body with feed, in livestock and poultry alimentary tract, form optimum micro-ecological environment, reduce the generation of livestock and poultry, build up one's resistance to disease, reduce the epidemic prevention cost, improve food conversion ratio, improve meat, Egg―qualites.
Beneficial effect of the present invention, the spirulina of employing microbial fermentation technology Preservation Treatment can obviously improve bird meat, Egg―qualites when feeding bird.The feed for preparing with this microbial fermentation processes is used for feeding the family chicken, and nursing its hair color of chicken out is bright-coloured, the full delicacy of muscle is flexible, the bright perfume (or spice) of mouthfeel.Add its protein concentration of this Spirulina Additive and obviously improve in laying hen, viscosity is high, and is strong to the parcel of yolk; The color of yolk increases redly than control group is obvious, and the yolk shape is perfectly round but not oblate, and the toughness of membrane of yolk strengthens, and boils very sweet-smelling of rear mouthfeel, the fine and smooth and larynx of not choking of yolk, and cholesterol level is the highest to descend 31%.
