Problems solved by technology

[0003] For alternative sources of fishmeal protein sources, there are plant-based protein sources and animal-based protein sources to replace fishmeal protein sources, while traditional plant-based protein sources (soybean meal, wheat flour, etc.) have various nutritional shortcomings, such as: lysine, methionine , threonine and other essential amino acids are low, and contain anti-nutritional factors such as gossamol, saponin, phytic acid, etc., traditional animal protein sources (meat and bone meal, blood meal, etc.), the amino acid composition ratio is unbalanced, and its composition is unstable and Disadvantages such as poor palatability

Embodiment 1

[0022] Tenebrio molitor powder, commonly known as "breadworm", has high nutritional value, high fat content, rich in inorganic salts and vitamins, rich in active functional substances, high in protein content, comprehensive and reasonable proportion of amino acids, and essential amino acids. The ratio accounts for more than 40% of the total amino acid ratio, which meets the requirements of FAO for excellent protein (as shown in Table 1). In addition, the special Tenebrio molitor used in this experiment is an excellent new variety (F88) specially bred for industrialized farming, and has the advantages of high protein content, low environmental pollution, water saving and land saving, etc. Pretreatment of the medium can increase the utilization rate of the medium by more than 15%.

Abstract

The invention belongs to the technical field of aquatic feed application, and discloses application of tenebrio molitor in promoting growth of litopenaeus vannamei, increasing nutritional value and improving intestinal flora. The litopenaeus vannamei is taken as a research object, the influence of the tenebrio molitor powder serving as a partial replacement source of the fish meal on the litopenaeus vannamei is researched, and the result shows that the tenebrio molitor powder has positive influence on the growth performance, immune performance, muscle fatty acid synthesis, intestinal flora and other aspects of the litopenaeus vannamei; therefore, a theoretical basis is provided for taking the tenebrio molitor powder 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 Tenebrio molitor in promoting the growth of Litopenaeus vannamei, improving the nutritional value and improving intestinal flora. Background technique [0002] With the rapid development of the aquaculture industry, the demand for aquaculture feed is increasing year by year. The supply of fishmeal as the main protein source of feed is in short supply, and due to the insufficient production of domestic fishmeal, the raw materials of fishmeal mainly rely on foreign imports, and the price of imported fishmeal High is one of the important factors for the high cost of breeding. Fishmeal has always been the most widely used source of high-quality protein in aquafeeds. Fishmeal not only has the advantage of high protein content, but also contains essential amino acids, and the amino acid composition is also very comprehensive. Litopen...
