Application of clostridium autoethanogenum protein in promoting growth of litopenaeus vannamei and improving intestinal flora

Abstract

The invention belongs to the technical field of aquatic feed application, and discloses application of clostridium autoethanogenum protein in promoting growth of litopenaeus vannamei and improving intestinal flora. According to the invention, litopenaeus vannamei is taken as a research object, the influence of clostridium autoethanogenum protein as a partial replacement source of fish meal on the litopenaeus vannamei is researched, and the result shows that the clostridium autoethanogenum protein has positive influence on the growth performance, immune performance, muscle fatty acid synthesis, intestinal flora and other aspects of the litopenaeus vannamei; and therefore, a theoretical basis is provided for taking the clostridium autoethanogenum protein as a partial replacement source of the fish meal.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed application, and more specifically relates to the application of Clostridium ethanol protein in promoting the growth of Litopenaeus vannamei and improving intestinal flora. Background technique [0002] Litopenaeus vannamei, commonly known as Penaeus vannamei, is a wide-temperature, wide-half tropical shrimp. The shrimp has delicious meat and high unit yield, and is one of the most important breeding objects in my country at present. Studies have shown that Litopenaeus vannamei has a high demand for protein, and the optimum protein level of the shrimp feed is 35% to 40%. As a marine animal protein raw material, fishmeal is irreplaceable or special in aquatic animal diets. The use of high-quality fishmeal is the main method to meet the high protein requirement of Litopenaeus vannamei. Fish meal is a representative raw material from marine fish. It has advantages in the composition mode of n...

Problems solved by technology

[0003] Animal protein, vegetable protein, and microbial protein are important protein sources. Animal protein sources such as blood meal, chicken meal, and meat and bone meal have high protein content and can replace part of fish meal, but they have essential amino acids such as isoleucine and lysine The acid content is insufficient, and the fat saturation in animal protein sources is high, which affects the palatability of fish; plant protein sources such as soybeans, rapeseed meal, and plant protein isolates have high protein content and mineral elements and vitamins It is rich and can partially replace fishmeal, but anti-nutritional factors in plant protein sources such as hemagglutinin and trypsin inhibitors will affect the growth of aquaculture animals and the flavor of feed; microbial proteins often come from bacteria, fungi, yeast, Single-cell algae, etc., single-cell protein is a kind of microbial protein, which has high protein content and balanced amino acid ratio, but the digestibility is low, and the safety needs to be further confirmed
