specific Embodiment approach 1

[0008] Specific embodiment 1: The feed used in the opening stage of sturgeon and salmon in this embodiment is composed of 10-15 parts of dextrin, 8-12 parts of whole milk powder, 8-12 parts of blood meal, 45-50 parts of white fish meal, 3-8 parts of soybean protein, 2-3 parts of soybean lecithin, 0.5-1.5 parts of L-alanyl-L-glutamine, 0.5-1.5 parts of hydroxymethyl cellulose It is composed of plain sodium and 1-2 parts of premix.

specific Embodiment approach 2

[0009] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the feed of sturgeon and salmon in the open period is composed of 11-14 parts of dextrin, 9-11 parts of whole milk powder, 9 ~11 parts of blood meal, 46 to 48 parts of white fish meal, 4 to 7 parts of soybean protein, 2.2 to 2.8 parts of soybean lecithin, 0.7 to 1.2 parts of L-alanyl-L-glutamine, 0.7 to It is composed of 1.2 parts of sodium hydroxymethyl cellulose and 1.2 to 1.8 parts of premix. Other components are the same as in the first embodiment.

specific Embodiment approach 3

[0010] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the feed of sturgeon and salmon in the open period is composed of 12.2 parts of dextrin, 10 parts of whole milk powder, 10 parts of blood meal, 47 parts white fish meal, 6 parts soy protein, 2.5 parts soy lecithin, 1 part L-alanyl-L-glutamine, 1 part sodium hydroxymethylcellulose and 1.5 parts premix . Other components are the same as in the first embodiment.

Abstract

The invention provides a feedstuff for sturgeon and hucho taimen at mouth - open period, which solves the problems of the conventional feedstuff that the growth rates of the sturgeon and hucho taimen are slow and the survival rates are low. The feedstuff comprises: dextrin, full cream milk powder, blood powder, white fish meal, soy protein, L-alanyl-L-glutamine, methylol cellulose and ore-mixing agent. When the feedstuff is used the for sturgeon and hucho taimen at mouth - open period, the growth rates and the survival rates of the sturgeon and hucho taimen are increased and the special growth rates of the sturgeon and hucho taimen are 1.5%-6.2% and the survival rates are more than 98%.

Description

technical field [0001] The present invention relates to a feed for sturgeon and salmon. Background technique [0002] Sturgeon and salmon are cold-water fish, and due to overfishing and environmental damage, wild sturgeon and salmon have been depleted in China. Therefore, artificial breeding of sturgeon and salmon is carried out to carry out resource proliferation and improvement. Artificial domestication is a very urgent task. The quality of the domestication effect in the opening period directly affects the success or failure of cultivating seedlings. The main factor that determines the growth of sturgeon and salmon in the opening period is the feed used in the opening period. There are problems with slow growth and low survival rate of sturgeon and jellyfish when they eat the existing conventional open-stage feed. SUMMARY OF THE INVENTION [0003] In order to solve the problems of slow growth rate and low survival rate of sturgeon and jellyfish when they eat convention...
