Abstract

The present invention discloses a low-protein prawn feed containing yeast nucleotides. The low-protein prawn feed comprises 18-35 parts of fishmeal, 2-3 parts of squid paste, 3-8 parts of shrimp shellpowder, 6.7-8.3 parts of soybean protein concentrate, 1-2 parts of blood powder, 4-6 parts of peanut bran, 3-5 parts of soybean meal, 32-32.8 parts of flour, 2-5 parts of fish oil, 1.5-3 parts of soybean lecithin oil, 0.1-0.3 part of cholesterol, 0.1-0.3 part of 35% Vc ester, 1-3 parts of calcium dihydrogen phosphate, 2-5 parts of zeolite powder, 0.1-0.5 part of 50% choline chloride, 0.1-0.5 partof a vitamin premix, 0.3-1 part of a mineral premix, 1-4 parts of a bonding agent, 5-8 parts of a filler, 0.2-0.5 part of crystal methionine and 0.8-2 parts of 5% yeast nucleotides. A protein contentin the feed is lower than that in commercially available feeds, and the low-protein prawn feed does not produce adverse effects on growth of the prawns, and is high in protein utilization and low incosts.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a low-protein prawn feed containing yeast nucleotides. Background technique [0002] Litopenaeus vannamei is one of the largest economically farmed prawns in the world. It has the characteristics of fast growth, high temperature resistance, miscellaneous food habits, wide-salinity, short breeding cycle, and high meat yield. China is the country with the highest shrimp farming area and output. [0003] In shrimp farming, the cost of feed accounts for about 50%-60%, and the use of protein raw materials determines the cost of feed. NRC (2011) recommends that the protein requirement of Litopenaeus vannamei is 35%-40%, but the protein content in the current commercial formula generally requires more than 42%, and high protein does not necessarily lead to efficient breeding returns. [0004] High protein content in feed does not mean high utilization rate of protein. In the ...
