Growth-promoting and disease-preventing compound feed for herrings

Abstract

The invention relates to a growth-promoting and disease-preventing compound feed for herrings. The growth-promoting and disease-preventing compound feed for the herrings comprises the following raw materials in parts by mass: 20-24 parts of corn bran, 18-22 parts of sweet potato starch, 15-18 parts of shrimp meal, 12-14 parts of soybean meal, 6-8 parts of river snail meat meal, 1-3 parts of wall-broken yeast powder, 1-2 parts of radix astragali powder,1-3 parts of spirulina powder, 0.5-1 part of edible salt, 3-5 parts of carrot powder, 2-4 parts of earthworm powder, 1-2 parts of fish oil, 2-4 parts of liquorice root powder, 0.5-1 part of vitamin C, 2-4 parts of hawthorn fruit kernel powder, and an appropriate amount of water. The compound feed disclosed by the invention provides nutrients suitable for growth demands of the herrings in a targeted way according to the growth habits and the physiological characteristics of the herrings, so that the compound feed is capable of promoting development of the herrings. The compound feed is capable of increasing appetite of the herrings so as to realize rapid growth of the herrings. Moreover, the compound feed is also capable of improving disease resistance of the herrings so as to prevent fish diseases and reduce disease incidence rates.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a herring compound feed for promoting growth and preventing diseases. Background technique [0002] Herring is a fish with a green color, mainly distributed in the plains south of the Yangtze River in my country, and relatively rare in the north of the Yangtze River; it is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river and the main breeding object in lakes and ponds , which is one of the "four major fish" in freshwater farming in my country. Herring is also known as black carp and snail green. Osteophytes, Cyprinidae. The body is sub-cylindrical, the individual is large, the growth is rapid, and the meat is delicious. It is the main freshwater fish breeding target in China. In recent years, the market demand is also very large, mainly because the breeding method is artificial breeding in fresh water,...

AI Technical Summary

Problems solved by technology

At present, fish feed generally has deficiencies such as insufficient nutrients, lack of nutrients, unreasonable distribution ratio of each component, weak disease resistance, high cost, etc., which affect the healthy and rapid growth of herring

In addition, herring may excrete a large amount of pollutants that are harmful to the environment after eating feed, which is very unfavorable to the growth of herring
