Efficient feed capable of promoting shelling growth of penaeus vanmamei and preparation method

Abstract

The invention belongs to the field of aquatic fermented feeds, and particularly discloses an efficient feed capable of promoting shelling growth of penaeus vanmamei. The efficient feed is characterized by being prepared from the following components in parts by weight: coconut cakes, full fat rice bran, pea protein powder, papain, a shelling element, beer yeast, bacillus subtilis, propolis-glucan gel microspheres, acylation emulsified oil powder and the like. The coconut cakes, the full-fat rice bran and the like which serve as fermented primary materials are matched with glutamine serving as a nutritional substance to prepare columnar compact fermented feed particles with a spiral type groove in the outer surface; then the groove is filled with a waterproof material to cover the whole product; the efficient feed is rich in nutrition, high in water resistance and good in feeding attraction effect; absorption and utilization of penaeus vanmamei are facilitated; by the matching of the added shelling element, shelling growth of the penaeus vanmamei can be promoted, and efficient aquaculture of the penaeus vanmamei can be jointly promoted.

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 promoting shelling and growth of 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 seawater or fresh water. ...

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
