Efficient feed capable of improving fleshy taste of freshwater penaeus vanmamei and preparation method of efficient feed

Abstract

The invention belongs to a fermentation feed for aquaculture, and particularly discloses an efficient feed capable of improving the fleshy taste of freshwater penaeus vanmamei. The efficient feed is characterized by comprising the following components in parts by weight: rice chaff, sodium iodide-enriched pickle fermentation liquid drying powder, coarse eucommia ulmoides powder, mannan oligosaccharide, nori polyphenol, loofah sponge, DHA micro-algal oil, pollens, propolis PM polypeptide hydrogel with a three-dimensional meshed structure, activated beer yeast powder and the like. Aiming at the demands of penaeus vanmamei for high quality, large quantity and efficient breeding, the invention provides columnar compactly fermented feed granules which are prepared by mixing a fermentation main material, glucosan, mannan oligosaccharide, nori polyphenol and the like and have spiral grooves in the surfaces; furthermore, the grooves are filled with waterproof materials at first, and the materials cover the outer layer of the whole product, so that the nutrition of the feed is guaranteed, the water resistance of the feed is improved, the dissolve-in-water rate is reduced, the loss is reduced, the attractant effect and the food taking effect are enhanced, the shrimp meat quality can be effectively improved, the yield can be increased, and efficient aquaculture is realized.

Description

technical field [0001] The invention belongs to the field of Penaeus vannamei feed, and in particular relates to a high-efficiency feed capable of improving the meat quality and taste of freshwater Penaeus vannamei and a preparation method. Background technique [0002] Penaeus vannamei (Penaeus vannamei), scientific name Litopenaeus vannamei, is one of the three largest species of farmed shrimp in the world. Penaeus vannamei was originally distributed in Central and South America, and the waters along the Pacific Ocean. my country introduced it from the United States in 1988 and succeeded in artificial batch breeding in 1994. The meat of Penaeus vannamei is fresh and tender, with a meat yield of over 65%. It is rich in nutrition, fast in growth, wide in salt range (0-40‰), high temperature resistant, and strong in disease resistance. Variety. In recent years, the cultivation of Penaeus vannamei in my country has made some progress whether in seawater, low-salinity seawate...

Problems solved by technology

Second, in the process of large-scale intensive farming, Penaeus vannamei is in a state of stress, resulting in low immunity. It is necessary to reduce stress and improve immunity through feed, rather than spraying drugs on the cultured water to prevent the occurrence of some common diseases.

Fifth, the requirement for prawn feed is green and environmentally friendly, and it cannot pollute the breeding water body, nor can there be drug residues in the body of Penaeus vannamei, causing food safety problems
