In recent years, with the scale of our country, intensify the gradual popularization of the aquaculture, the sea water cultivates the disease day by day seriously, often bring the deadly blow to feeding . And the security of" entry " aquatic products, is often the question that people care about at first. Some antibiotic medicines, residue in aquatic animal’s organism of active material of living beings, often influencing the human health directly. It must establish the environmental protection idea to solve this problem fundamentally, develop , develop and popularize function of use strong , price low , performance excellent, nonpoisonous side effect, benefit green fodder additive of aquatic products of environmental protection in a more cost-effective manner. This subject aims at developing a kind of new-type natural bait additive, this additive takes Nisin as the core, have put into the traditional Chinese medicine of antivirus which increases the immunity. For this reason, we have carried on a series of tests: Getting blue and overcast to leather, positive restrain of fungus test; Toxicity is tested; To bait antiseptic research that keep fresh, and is it test to throw in, and to take with citric acid for acid pharmaceutical make preliminary research. The result is as follows:1. Nisin has remarkable inhibition on such G+ funguses as little coccus of gamboge , golden yellow staphylococcus ,etc; Although a haemolysis vibrio is a G- fungus , Nisin has very strong restraining the fungus result to it; Between Nisin and colon bacillus , have a liking for aqueous vapor form afterbirth fungus , fluorescence false form afterbirth fungus ,etc. G" fungus have no bacteriostasis.2. Between citric acid and packs of haemolysis vibrio , have a liking for aqueous vapor form afterbirth fungus , fluorescence false form afterbirth fungus have bacteriostasis. Nisin dissolve on citric acid improving three fungus these separately to citric acid , sensitiveness of Nisin obviously after the solution. Nisin and traditional Chinese medicine compound liquid together to G+ fungus if gamboge little coccus , golden yellow staphylococcus, and to G- fungusif packs of haemolysis vibrio , have a liking for aqueous vapor form afterbirth fungus , fluorescence false form afterbirth fungus , colon bacillus have bacteriostasis. Traditional Chinese medicine density does not change, is it compound with fungus to Nisin and traditional Chinese medicine sensitiveness of the liquid strengthen with increase of Nisin density to test.3. Nisin and traditional Chinese medicine compound liquid feed black carp test together. Fodder add Nisin contrast group increase weight rate high 15.2% compared with group of medicine made of two or more ingredients of traditional Chinese medicine, demonstrate the obvious function of increasing weight. Dissect the black carp, observe the liver pancreas. It is unusual to discover having, it is obvious Nisin and traditional Chinese medicine compound the liquid is that the security has no one that is poisonned.4. Through bait microorganism , pH value and survey , sense organ of quality is it examine Nisin , citric acid , traditional Chinese medicine compound between liquid and antiseptic application result that keeps fresh of bait to come correctly. When Nisin , citric acid , traditional Chinese medicine are used alone or jointly, on the basis of the inhibition in various degree to the microorganism, and influence pH value and sense organ quality further. Nisin , citric acid and traditional Chinese medicine cooperate with the result of use to be best, the adding amount is respectively 0.02%, 0.15%, 1%.5. Nisin and traditional Chinese medicine compound liquid is it mix to go on with proportion of lg:25mL , cooperate and use feeding Luo’s natural pond shrimp, the adding amount is 1%. Additive feed Luo result, natural pond of shrimp indicate , the additive has good urging to grow, improve shrimp’s body immunity , resistance against diseases , is able to bear the result which is short of oxygen , can increase production .
