Special puffed feed for penaeus vannamei

Abstract

The present invention provides a special puffed feed for penaeus vannamei. The special puffed feed for the penaeus vannamei comprises the following components in parts by weight: 15-35 parts of fish meal, 13-24 parts of wheat flour, 3-5 parts of soybean lecithin, 16-23 parts of fermented soybean meal, 10-20 parts of green alga powder, 2-4 parts of lactic acid bacteria, 2-4 parts of mineral flour, 4-9 parts of fish dissolved pulp proteins, 1.2-2.5 parts of monocalcium phosphate, 11-24 parts of peanut meal, 8-13 parts of cottonseed proteins, 4-10 parts of shrimp shell flour, 4-8 parts of soybean oil, 0.3-0.8 part of non-starch polysaccharide enzyme and 1-3 parts of an attractant. The feed is reasonable in nutrition proportions, can effectively promote growth of the penaeus vannamei, improves immunity and anti-stress ability of the penaeus vannamei, improves a survival rate, reduces a cost of feeding, is also high in stability in water and low in feed coefficients, and can also maintain good algal facies in water body, remove ammonia nitrogen content in water and purify water quality.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a special extruded feed for Penaeus vannamei. Background technique [0002] The adult Penaeus vannamei can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. The legs are often chalky, so they are called white-legged shrimps. The distribution belongs to Arthropod (Arthopoda), Crustacea (Crustacean), Decapoda (Decapoda), Swimming suborder (Natantia), Penacidae (Penacidae), Penaeus (Penaeus), Litopenaeus subgenus. It is a wide-temperature and wide-salt tropical shrimp. [0003] Since 1988, my country has carried out the introduction, adaptive breeding and large-scale promotion of Penaeus vannamei in China; In 1994, a small batch of shrimp fry was successfully cultivated; until 1999, Tianjun Industry, a national-level agricultural leading company in Shenzhen, Guangdong Province, cooperated with a ...

Problems solved by technology

The microbial fermented feed for Penaeus vannamei of the invention is suitable for the period of rapid increase in the feeding amount of Penaeus vannamei in the middle and late stages of culture. It is a health function to improve feed utilization and digestion and absorption rate, protect the liver of Penaeus vannamei, and promote the balance of intestinal bacteria. However, the fermentation strains of this feed are not comprehensive, and the quality of feed fermentation may not be high. After feeding, it may cause indigestion of Penaeus vannamei, which may affect the growth of Penaeus vannamei
