Application of Antarctic krill powder in respect of preparing starter feed for blood parrots

Abstract

The invention discloses an application of Antarctic krill powder in the respect of preparing a starter feed for blood parrots and a special starter feed for the blood parrots. The starter feed is prepared from the following components in percentage by mass: 5-75% of Antarctic krill powder, 1-20% of soybean protein concentrate, 1-10% of silkworm chrysalis meal, 1-7% of cricket powder, 5-24% of low-gluten flour, 2-10% of beer yeast powder, 1-5% of a yeast extract, 4-20% of artemia salina, 2-4% of soybean lecithin, 2-4% of betaine, 1-2.5% of a vitamin mixture, 2-5% of a mineral element mixture, 1-5% of bacillus subtilis, 1-5% of an immunopotentiator and 0.1-1% of pagodatree flowers, wherein the fluorine content of the Antarctic krill powder is lower than 1mg / kg. The special starter feed is researched and developed in accordance with the physiological digestion characteristics, the growth characteristics and the ingestion preference of young blood parrots at a starter stage, has excellent food calling properties, can sufficiently meet nutritional requirements of the young blood parrots at the starter stage, and can improve the immunity, the stress resistance and the survival rate of blood parrot fingerlings.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to the application of Antarctic krill powder in the preparation of blood parrot mouth feed. Background technique [0002] The blood parrot is commonly known as the red god of wealth and the fish of wealth. Its adult body is 15 to 20 centimeters long, with a wide and thick body and an oval shape. The whole body of the blood parrot is bright red, with a chubby body and soft fins. The color is red and very pleasing. It is an important ornamental fish. [0003] The breeding of blood parrot fry has considerable economic benefits, and the opening of fry is of great significance, which has a crucial impact on the survival rate and weight gain rate of fry. Before hatching, fry are greatly affected by the environment, and the mortality rate is high; after hatching, various survival indicators increase significantly. Therefore, in the breeding and production of this kin...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the lack of research on the existing blood parrot fry opening technology and the problem of high fluorine content in Antarctic krill meal, prepare Antarctic krill meal with a fluorine content of less than 1mg / kg, and then optimize a The special opening material for blood parrots is developed for the growth, physiological digestion characteristics and feeding preferences of blood parrot seedlings at the opening stage. The special opening materials have good food-attracting properties for blood parrot seedlings, which can fully meet their nutritional needs during the opening stage and improve Immunity, anti-stress ability, survival rate and weight gain rate of blood parrot fry
