Fermented feed for penaeus vannamei

Abstract

The invention provides a fermented feed for penaeus vannamei. The fermented feed is prepared from the ingredients in parts by weight: 15-35 parts of wheat flour, 13-24 parts of maize flour, 2-6 parts of soybean lecithin, 15-27 parts of fermented soybean meal, 10-20 parts of schizochytrium powder, 8-17 parts of leavening agent, 3-6 parts of composite mineral substances, 4-9 parts of fish soluble extract, 10-22 parts of peanut meal, 8-13 parts of cottonseed protein, 6-12 parts of shrimp shell powder and 3-8 parts of growth promoter. According to the feed, nutritional ingredients in the feed are converted into micromolecular substances by using the leavening agent, so that the digestive absorption of the penaeus vannamei is promoted; the nutritional proportioning ratio is reasonable, so that the growth of the penaeus vannamei can be effectively promoted, and the immunity is improved; the feed utilization ratio is high, so that the economic value of culture is increased; the feed has high stability in water and can be used for maintaining a good algal phase for a water body, removing ammonia nitrogen content from the water and purifying the water.

Description

technical field [0001] The invention belongs to the scope of aquatic feed, in particular to a fermented feed for Penaeus vannamei. Background technique [0002] Penaeus vannamei is mainly distributed in the tropical waters of the western Pacific coast of the United States, from the Gulf of Mexico to the central part of Peru, and is more concentrated in the waters near Ecuador. Penaeus vannamei has a thin shell, its normal body color is blue, and it has no markings all over its body. Its shape is similar to that of Penaeus chinensis. It naturally inhabits sea areas with a water depth of 0-70m and is omnivorous. It has delicious meat, high meat yield, wide salinity, and high temperature resistance. Its seedlings can grow into adults after more than 100 days of cultivation, and the body length can reach 24cm. [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 shri...

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
