Compound feed for penaeus vannamei

Abstract

The invention discloses a compound feed for penaeus vannamei and belongs to the field of formulas of feeds for shrimps. The compound feed is prepared from the following components in parts by weight: 50-70 parts of corn, 30-40 parts of bran, 10-20 parts of shell powder, 3-10 parts of brewer's grains, 2-5 parts of salt, 3-6 parts of spirulina, 3-6 parts of soybean oil, 10-20 parts of reed powder, 5-10 parts of amino acid mixture, 2-6 parts of microelement, 5-10 parts of binder, 1-5 parts of calcium hydrophosphate, 3-5 parts of eggshell, 2-5 parts of yeast powder and 2-5 parts of complex vitamins. The compound feed for penaeus vannamei is used for solving the problems of slow growth, weak disease resistance and low survival rate of the penaeus vannamei; the compound feed provides comprehensive and sufficient nutrition for the penaeus vannamei, can be quickly ingested by the penaeus vannamei and also can be effectively digested, absorbed and utilized, and therefore, the penaeus vannamei is promoted to grow quickly and the survival rate of the penaeus vannamei is high; the compound feed is good in stability in water and can be ingested by the penaeus vannamei better; as a result, the loss of nutrient substances is effectively reduced, the eutrophication pollution on the aquatic water is reduced and the sustainable development of the shrimp industry is effectively promoted.

Description

technical field [0001] The invention relates to the formulation of animal feed, in particular to a compound feed for Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. Penaeus vannamei is native to the Pacific coast of South America. Professor Zhang Weiquan of the Institute of Oceanology, Chinese Academy of Sciences first introduced this shrimp from the United States. Jiangsu, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted breeding. [0003] The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, the suitable temperature range is wide, it can grow at 18-32 ℃, and the salt range is also wide, and it can grow under the condition of salinity 1-40‰. desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has ...

AI Technical Summary

Problems solved by technology

Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in southern my country. During the breeding process of Penaeus vannamei, due to the unbalanced nutrition and poor food attraction of the existing Penaeus vannamei compound feed, etc. defects, and poor stability in water, which is not conducive to fast and effective feeding of Penaeus vannamei, resulting in slow growth, weak disease resistance, and low survival rate of Penaeus vannamei. Therefore, the existing feed of Penaeus vannamei is difficult to meet the requirements of Feeding requirements are not conducive to the healthy and sustainable development of the vannamei farming industry
