Penaeus vannamei compound feed and processing method thereof

Abstract

The present invention relates to a penaeus vannamei compound feed which includes the following raw materials in parts by mass: schizochytrium limacinum meal 15-20 parts, fish meal 20-25 parts, shrimp shell powder 2-4 parts, cuttlefish powder 2-4 parts, peanut meal 10-15 parts, soybean meal 15-20 parts, flour 15-20 parts, complex vitamins 0.3-0.4 part, choline chloride 0.3-0.4 part and zeolite powder 2-3 parts. The replacement of part of fish meal with the schizochytrium limacinum meal reduces the feed costs; The addition of the schizochytrium limacinum meal enables the amino acids of the feed to be more balanced and complementary, therefore improving the feed efficiency; the schizochytrium limacinum meal is rich in active substances which can enhance the immune function of the penaeus vannamei, prevent the occurrence of diseases, reduce drug use in shrimp farming, improve the survival rate and growth rate of the penaeus vannamei. The schizochytrium limacinum meal contains DHA, significantly reduces or completely doesn't require the addition of fish oil, reduces the excessive reliance on fish meal and fish oil, and the marine fish resources are protected, at the same time the feed cost is reduced and the shrimp farming benefit is improved.

Description

technical field [0001] The invention relates to a prawn feed, in particular to a compound feed of Penaeus vannamei and a processing method thereof. Background technique [0002] Vannamei white shrimp scientific name vannamei ( Penaeus vannamei Boone), native to the waters of the Pacific coast of the Americas. Penaeus vannamei has the advantages of strong adaptability, wide salt tolerance, rapid growth, long breeding period, strong disease resistance, delicious meat, and high yield of processed meat. It is recognized as one of the excellent varieties of prawn farming in the world. It has developed rapidly since it was introduced into my country in 1988. At present, both the aquaculture area and the total output rank first among the aquaculture species of prawns. With the continuous development of the aquaculture industry, the research and development work on the nutrition of Penaeus vannamei and its feed has also increased, mainly focusing on the demand for protein, amino ...

Problems solved by technology

[0006] One of the current research directions for prawn feed is to use plant protein to replace animal protein in fish meal. However, in the existing prawn feed, peanut meal, soybean meal, and flour all contain a large amount of plant protein, and plant protein is used instead of fish meal. The effect of animal protein is not ideal, it will inhibit the growth and feed conversion rate of prawns
