Problems solved by technology

[0004] At present, the feeds fed to pangasius juveniles are general-purpose fish feeds, also known as open feeds. Because they contain a lot of fat, protein and vitamins, a large amount of anti-oxidant and antibacterial agents are added during production. Commonly used artificial Antioxidants are butylated hydroxytoluene, butylated hydroxymethoxybenzene, tocopherol, ethoxyquine, especially ethoxyquine is widely used in fish feed, these antioxidants reduce free radicals or reduce oxidase activity To slow down the oxidation of feed, but it will also affect the development of the fish's own organs and metabolism, especially in the juvenile stage of organ development, resulting in the unsound development and loss of function of some juvenile organs, which in turn affects the juvenile stage survival rate

Abstract

The present invention discloses a special compound feed for juvenile Basa fish and a preparation method thereof. By using natural antioxidants and natural antifungal agents to replace traditional synthetic chemical antioxidants and antifungal agents, the method not only effectively prevents feed oxidation and mildew, but also eliminates the influence of synthetic chemical antioxidants on the development of Basa fish in a juvenile stage, thereby improving the survival rate of juvenile Basa fish; through the addition of tea, folium eucommiae and garlic, the compound feed is natural and green, and has no side effects on the development of juvenile fish, but also improves the immunity and digestive capacity of the juvenile fish; and through the rational combination of fat, protein and vitamins, the compound feed effectively provides essential nutrients for the growth and development of Basa fish during the juvenile stage, and is more suitable for the healthy development of various organs.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a special compound feed for juvenile pangasius and a preparation method thereof. Background technique [0002] Pangasius is an important freshwater aquaculture species in Southeast Asian countries. It has the characteristics of fast growth, high yield, low oxygen resistance, and strong disease resistance. It has strong adaptability to water quality and environment and does not require high breeding technology. The main ingredients of boiled fish, pan-fried fish, Western-style fried fish steak, baked fish steak, etc. With the rapid growth of pangasius in my country's terminal consumption market and the huge profits Vietnam pangasius has gained in my country's market, domestic investment in pangasius farming has continued to increase, especially the rapid rise of Guangxi, Guangdong and Hainan. [0003] In the pangasius breeding stage, the most critical period is the juvenile per...
