The spiral algae widely distributes in the world various sea areas and the land pale, in the salt water lake, is nucleus biology which the float is self-supportive, is the blue-green algae oscillatoria item oscillatoria branch. The algae body as a result of assumes the green including the algae blue element, the microscope observation assumes the thin filiform helix. The world known has 36 kinds, at present on the international factorization production mainly obtusely goes against the spiral algae nucleus enormous spiral algae 2 fresh water types. The spiral algae is the present commonly used micro algae (chlorella, green alga, spiral algae) the protein content is highest, the nutrition most entire, the digestion absorption and the palatability best algae, moreover the edible security, the discovery poison side effects and so on has not until now had any toxicity to the animal or sends. First, The spiral algae's nutrition characteristic 1, the protein content high spiral algae reaches as high as including the protein 55%-70%, also excellent in quality, easy to digest the absorption, does not contain any digestion absorption barrier factor. According to reported its protein true nutritive value is approximately above 75%, the biology value is 79.5%-87.7%. Beijing Aquatic product Research institute obtains the grass carp and the young shrimp surpasses 80% to its protein absorption rate. In the spiral algae protein includes 18 kind of amino acids, each kind must the amino acid content be all high, only then the methionine content is low, but also is higher than other albumen. 2: In the carbohydrate component special spiral algae contains the carbohydrate 15%-25%, in which mannitol 7%-9%, methyl sugar 7%, alginic acid 24%-29%,Mouse Li sugar 5%-6%, ***ermination sugar 14.4%. This is completely different with the conventional vegetative feed component, specially the alginic acid and the manna acid for the aquatic product precious animal must, the polysaccharide which contains have adjust and enhance orga |
