Efficient feed capable of promoting immunity of penaeus vannamei boone and preparation method

Abstract

The invention belongs to the field of aquatic product fermented feeds and particularly discloses an efficient feed capable of promoting the immunity of penaeus vannamei boone. The efficient feed is characterized by being prepared from the following components in parts by weight: peanut meal, apple seed meal, euphausia superba shrimp head meal, resveratrol, astragalus extract, enveloped allicin, crushed bacillus, aminophylline, loofah sponge, propolis-polylactic acid hydrosol and a microorganism compound bacteria liquid. Aiming at the efficient cultivation requirements of the penaeus vannamei boone, the invention provides a columnar compact fermented pellet feed which is prepared by combining fermented main materials capable of improving the immunity with nutrient substances and has a spiral groove on the surface; furthermore, the spiral groove is filled with waterproof materials, and a whole outer layer is covered, so that the water resistance of the feed is improved; and the nutrients of the feed can be easily kept, the food calling effect is improved, the immunity of the penaeus vannamei boone is improved and the cultivation efficiency is improved.

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 immunity 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. The cul...

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
