Liver-protecting gallbladder-protecting expanded grass carp compound feed and preparation method thereof

Abstract

A liver-protecting gallbladder-protecting expanded grass carp compound feed and a preparation method thereof belong to the field of fish feed. The expanded grass carp compound feed includes the following raw materials by mass: 5-20% of animal protein raw materials, 38-55% of vegetable protein raw materials, 2-10% of single cell protein raw materials, 7.5-24.5% of energy raw materials and the balance ingredients. The vegetable protein raw materials include fermented soybean meal. The ingredients include carnitine, complex vitamins, complex mineral salts and emulsifiers. The preparation method includes mixing and granulating the raw materials of the expanded grass carp compound feed. The needs of grass carp culture in different seasons, especially in high temperature seasons for nutrition, gastrointestinal conditioning and hepatobiliary care can be met.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to a liver-protecting gallbladder-protecting extruded grass carp compound feed and a preparation method thereof. Background technique [0002] The extruded feed is the feed in the environment of high temperature, high pressure, high shear force and high water content, through continuous mixing, conditioning, heating, pressurization, curing, extrusion die hole and sudden pressure reduction to form a bulky and porous feed. Compared with pellet feed: low feed coefficient, lower feed cost; low powder content, less waste; fully ripened, good absorption effect, good breeding effect. [0003] However, in the middle and late stages of grass carp farming, with the continuous increase of food intake, grass carp grows rapidly, especially in summer, the water temperature is high, which leads to frequent occurrence of hepatobiliary syndrome and greatly reduces the survival rate of grass carp farming, wh...

Problems solved by technology

[0003] However, in the middle and late stages of grass carp farming, with the continuous increase in food intake, grass carp grows rapidly, especially in summer, when the water temperature is high, causing grass carp to frequently suffer from hepatobiliary syndrome and greatly reducing the survival rate of grass carp farming. This has become the current grass carp farming industry. technical bottlenecks
