Embodiment 1

[0052] Example 1 Preparation of low-fluorine Antarctic krill meal

[0053] 1. Preparation of modified bagasse powder:

[0054] (1) bagasse is pulverized and sieved to obtain bagasse powder after being dried or sun-dried;

[0055] (2) Soak bagasse powder in 25% sodium hydroxide solution for 6.5 hours, wash and filter;

[0056] (3) Soak in 1.7g / L potassium permanganate solution and react at 60°C for 2 hours;

[0057] (4) Washing, filtering, and drying the processed product in (3) to obtain modified bagasse powder.

[0058] 2. Preparation of low-fluoride Antarctic krill meal:

[0059] (1) Antarctic krill was thawed, screened, and cleaned in still water, kept in 80°C water for 10 minutes, then immersed in distilled water with a pH of 4.8, and pre-defluorinated by 100W ultrasonic treatment for 4 hours. During the treatment, the distilled water was changed every 1 hour;

[0060] (2) Use modified bagasse powder for defluorination treatment: add the modified bagasse powder into di...

Embodiment 2

[0064] Embodiment 2 Low-fluorine Antarctic krill meal preparation process optimization

[0065] 1. Effect of modified bagasse powder on the fluorine content of Antarctic krill powder

[0066] (1) Effect of concentration of sodium hydroxide solution on fluorine content in krill meal

[0067] According to the method for preparing modified bagasse powder in Example 1, a series of modified bagasse powders were prepared with the concentration of sodium hydroxide solution as the single variable. Then follow the method for preparing Antarctic krill meal in Example 1 to obtain a series of Antarctic krill meal. Determination of fluorine content in Antarctic krill meal and calculation of shrimp meal yield.

[0068] The results are shown in Table 1. When the concentration of sodium hydroxide solution is 25-35%, the fluorine content of Antarctic krill meal is lower.

[0069] Table 1 Effect of concentration of sodium hydroxide solution on fluorine content in krill powder when bagasse po...

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...
