Problems solved by technology

Feed protein accounts for the largest proportion of the entire fish feed cost. Fishmeal has a complete range of amino acids, a reasonable proportion, and high nutritional value. It is the preferred protein raw material for aquatic feed. Expensive, leading to high prices of aquatic feed
The use of fishmeal will gradually be limited
Although plant-based protein generally has the disadvantages of poor quality, poor palatability and more anti-nutritional factors, etc.

Abstract

A Paralichthys olivaceus juvenile feed comprises 45-55% of fish meal, 15-20% of bean meal, 3-8% of alpha-starch, 1-4% of shrimp peel meal, 2-5% of brewers' yeast, 2-5% of corn protein powder, 2-5% of soybean phospholipids, 0.5-1.5% of squid internal organ powder, 0.5-1.5% of blood powder, 10-15% of wheat flour, 0.1-0.2% of betaine, 0.1-0.3% of choline chloride, 1-1.5% of fish oil, 0.1-0.3% of multiple vitamins and 1-3% of minerals. The Paralichthys olivaceus juvenile feed prepared in the invention adopts botanical white bean meal to substitute parts of animal proteins, so the cost of the feed is reduced; and the proportion of the bean meal is controlled to be 15-20%, so balanced nutrition of the feed is guaranteed, and the growth performance of Paralichthys olivaceus juveniles is not influenced.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to a feed for juvenile flounder fish. Background technique [0002] Flounder is an important species of marine culture in my country, which requires a high level of feed protein and is highly dependent on animal protein. Currently, the proportion of fishmeal used in commercial feed for flounder accounts for more than 50%. In order to reduce feed costs, feed Also added a certain proportion of plant-based protein raw materials. Protein is the material basis for the growth and development of fish, mainly derived from animal and plant protein raw materials. Feed protein accounts for the largest proportion of the entire fish feed cost. Fish meal has a complete range of amino acids, a reasonable proportion, and high nutritional value. It is the preferred protein raw material for aquatic feed. Expensive, leading to high prices of aquatic feed. The use of fishmeal will gradually be limited. Al...
