Embodiment

[0018] A low-protein diet to improve growth performance of Litopenaeus vannamei:

[0019] 1) The ingredients of the low-protein feed include: nucleotides (5'-cytidylic acid, 5'-adenylic acid, 5'-inosinic acid disodium, 5'-uridine acid disodium, 5'- Disodium guanylate and disodium 5′-thymidylate are mixed at a mass ratio of 1:1:1:1:1:1, the ratio can be adjusted according to the actual situation, and the amount of each nucleotide used is controlled at 15-25 %), fish meal, squid paste, shrimp shell powder, soybean protein concentrate, blood meal, peanut bran, soybean meal, flour, fish oil, soybean lecithin oil, cholesterol, 35% VC ester, calcium dihydrogen phosphate, zeolite powder, 50% chloride Choline, vitamin premix, mineral premix, sodium carboxymethylcellulose, cellulose, and crystalline methionine;

[0020] In this implementation case, an experimental group and a control group (4 groups in total) were respectively set up with the feed of the low-protein group and the high...

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a low-protein feed for improving growth performance of litopenaeus vannamei and application thereof. The low-protein feed comprise nucleotide, and is used for improving the digestion and absorption capacity of the litopenaeus vannamei to nutrient substances in feed, improving growth performance of the litopenaeus vannamei, improving the body composition and serum biochemical indexes of the litopenaeus vannamei and improving immunity of the litopenaeus vannamei. The nucleotide comprises 5'-cytidylate, 5'-adenylate, disodium 5'-inosinate, disodium 5'-uridylate, disodium 5'-guanylate and disodium 5'-thymidylate. The low-protein feed of the present invention is mainly used for improving crude fat content,serum glutamic oxalacetic transaminase and glutamic-pyruvic transaminase, hepatopancreatic glutamic-pyruvic transaminase, blood cell count, serum PO activity and the total protein content in stomachsand intestinal tracts of the litopenaeus vannamei.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a low-protein feed for improving the growth performance of Litopenaeus vannamei and an application thereof. Background technique [0002] my country is a big aquaculture country, and its aquaculture output has ranked first in the world for many years. Feed protein is the main energy source for aquatic animals. The protein resources (such as fishmeal) used by my country's aquatic feed industry have been in short supply for a long time, and the degree of dependence on imports is high, which restricts the sustainable development of my country's aquatic feed industry and aquaculture. However, with the rapid development of aquaculture in my country, the industrial model is gradually changing to high-density and intensive intensive farming. The increase in wastewater in the breeding process is likely to cause water pollution and damage the ecological environment, which...
