[0003] In recent years, the price of fishmeal has been maintained at a high level due to the influence of supply and demand, which has greatly affected the production and sales of prawn feed, and the relative decline in the benefits of farmers
Therefore, under the premise of ensuring the normal growth of prawns, using fermented soybean meal to partially replace fish me

Abstract
The invention relates to an aquatic feed and in particular relates to an improved litopenaeus vannamei feed. The litopenaeus vannamei feed is prepared from the following ingredients in percentage by weight: 18-23 percent of flour, 18-24 percent of imported fish meal, 3-7 percent of shrimp head meal, 3-7 percent of beer yeast, 10-20 percent of soybean meal, 8-13 percent of fermented soybean meal, 10-15 percent of peanut bran, 1-5 percent of soybean soil, 2-6 percent of phospholipid, 1-2 percent of monocalcium phosphate, 2 percent of a prawn compound premix, 0.1-0.3 percent of Lys hydrochloride (78%) 0.05-0.15 percent of L-methionine and 0.3-0.5 percent of choline chloride (50%). The litopenaeus vannamei feed has the characteristics that the contents of protein, fat, calcium, phosphorus, Lys and Met in the feed basically remain unchanged compared with the current feed, and the cost is greatly reduced.
Description
technical field [0001] The invention relates to aquatic feed, in particular to the improvement of feed for Penaeus vannameim. Background technique [0002] Shrimp is an important aquaculture species in my country. According to the 2011 China Fishery Statistical Yearbook, the output of Litopenaeus tavannamei in my country in 2010 exceeded 1.22 million tons, and the aquaculture area was about 250,000 hectares. In order to meet the healthy growth of Penaeus vannamei, the feed for Penaeus vannamei must contain protein, fat, calcium, phosphorus, Lys, Met, etc. The current feed for Penaeus vannamei mainly consists of flour, imported fish meal, shrimp head powder, beer yeast , soybean meal, peanut bran, soybean oil, phospholipid powder, calcium dihydrogen phosphate, prawn compound premix, choline chloride (50%), etc., and their mass percentages are respectively 18-23, 27-33, 5- 10, 3~7, 10~20, 10~15, 1~5, 2~6, 1~2, 2, 0.3~0.5 (the sum of the mass percentage of each component is 1...
