Compound feed for acipenser ruthenus juveniles and preparation method thereof

Abstract

The invention relates to a compound feed for acipenser ruthenus juveniles, and further relates to a preparation method of the compound feed for the acipenser ruthenus juveniles. The compound feed for the acipenser ruthenus juveniles comprises the following ingredients in parts by mass: 20-30 parts of bean curd shred powder, 4-13 parts of silkworm chrysalis powder, 6-15 parts of alfalfa seed powder, 5-14 parts of Qula, 4-13 parts of willow shoots, 6-14 parts of mulberry leaves, 5-16 parts of Maonicai (a kind of wheat-field wild herbs in northern Anhui Province and Henan Province of China), 4-14 parts of purple flower holly leaves, 5-14 parts of gardenia jasminoides, 6-16 parts of cortex fraxini, 3-9 parts of plantago depressa, 2-9 parts of chicken's gizzard-skin, 3-10 parts of fish oil, 1-6 parts of honey, 2-6 parts of olive oil and 1-4 parts of complex multi-vitamins. The compound feed for the acipenser ruthenus juveniles is provided by the invention according to energy metabolism modes and nutrient requirements of the acipenser ruthenus juveniles, so that fish meal is completely replaced. The acipenser ruthenus juveniles fed with the compound feed are high in survival rates, low in feed coefficients and high in specific growth rates.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for juvenile sturgeon; the invention also relates to a preparation method of the compound feed for juvenile sturgeon. Background technique [0002] The body of the sterlet is long conical, and the body is covered with 5 rows of bone plates, and small comb-like particles are scattered between the bone plates. The rostrum is slightly blunt or pointed, the mouth is small and transversely split, and the middle part of the lower lip is broken. The distinguishing features from other sturgeons are: a small mouth in the middle of the lower collar, more than 50 lateral bone plates, and a small sturgeon body The color changes greatly, the back is often dark grayish brown, and the abdomen is yellowish white. [0003] At present, fishmeal is widely used as the main protein source in the compound feed of juvenile sturgeon. Fishmeal is the closest to the amino acid ratio required by aquatic ani...

AI Technical Summary

Problems solved by technology

Fishmeal is the closest to the amino acid ratio required by aquatic animals. Adding fishmeal can ensure the rapid and healthy growth of aquaculture animals. When other protein sources are used instead of fishmeal to prepare compound feed for juvenile sturgeon, the quality of the feed is often difficult to guarantee. Can affect the normal growth and development of juvenile sturgeon

However, with the rapid development of the aquaculture industry, the demand for aquatic feed has increased rapidly, and the problem of the shortage of domestic fishmeal resources has become increasingly prominent. During the growth process of fish, due to lack of resistance, various fish diseases will occur, which will affect the survival rate of sterlets. Sturgeon juvenile growth and disease-resistant formula feed for sterlet juveniles is an urgent problem to be solved in the current sterlet breeding industry
