Description

Technical field

[0001] The invention belongs to the field of feed for snakehead fish and a preparation method thereof, and in particular relates to a formula and a preparation method of an extruded compound feed for snakehead fish.

Background technique

[0002] There are only two genera and 8 species of snakeheads in my country, among which snakeheads and snakeheads have become important economic fish in freshwater aquaculture in my country. The meat of the snakehead is delicate, delicious, with fewer thorns and more meat, and rich in nutritional value. It has medicinal functions such as removing blood stasis and promoting body fluid, nourishing and recuperating, removing dampness and diuresis, promoting muscle and blood, and healing wounds. Channa, also known as Seven Star Fish, is a hot-selling aquatic product in the markets of Guangdong, Hong Kong, Macao and Southeast Asian countries, and it is also a famous and high-quality aquatic product that earns foreign exchange...

Examples

Embodiment 1

[0014] Embodiment 1: Preparation of puffed compound feed 1 for Channaidae fish

[0015] A. Weigh 48kg of steamed fish meal, 15kg of fermented soybean meal, 6kg of meat and bone meal, 5kg of blood meal, 3kg of beer yeast, 3kg of mantis shrimp paste, 2kg of fish oil, 15kg of high-gluten flour, 1kg of liquid phospholipid, 0.5kg of calcium dihydrogen phosphate, and multivitamin ( Commercially available) 0.5kg, compound minerals (commercially available) 0.5kg, choline chloride 0.5kg;

[0016] B. After mixing evenly, it is pulverized by a superfine pulverizer, so that all ingredients can pass through the 80-mesh sieve;

[0017] C. The pulverized material is fed into the modem with 16kg of steam at 90°C for 7 minutes, and then the raw material enters the extruder pelletizer at a temperature of 105°C for granulation;

[0018] D. Dry the extruded feed pellets at 90°C.

Embodiment 2

[0019] Embodiment 2: Preparation of puffed compound feed 2 for Channaidae fish

[0020] A. Weigh 50kg of steamed fish meal, 20kg of fermented soybean meal, 5kg of blood meal, 3kg of beer yeast, 4kg of mantis shrimp paste, 2kg of fish oil, 12kg of high-gluten flour, 1kg of liquid phospholipid, 1kg of calcium dihydrogen phosphate, and 1kg of multivitamin (commercially available), Compound minerals (commercially available) 0.7kg, choline chloride 0.3kg;

[0021] B. After mixing evenly, it is pulverized by a superfine pulverizer, so that all ingredients can pass through a 100-mesh sieve;

[0022] C. The pulverized material is fed into the modem with 16kg, 95°C water vapor for 6 minutes, and then the raw material enters the extruding extruder granulator at a temperature of 100°C for granulation;

[0023] D. Dry the extruded feed pellets at 98°C.

Embodiment 3

[0024] Embodiment 3: Preparation of puffed compound feed 3 for Channaidae fish

[0025] A. Weigh 35kg of steamed fish meal, 20kg of fermented soybean meal, 10kg of meat and bone meal, 5kg of silkworm chrysalis powder, 2kg of beer yeast, 3kg of fish oil, 20kg of high-gluten flour, 2kg of liquid phospholipid, 1kg of calcium dihydrogen phosphate, and 1kg of multivitamin (commercially available), Compound minerals (commercially available) 0.5kg, choline chloride 0.5kg;

[0026] B. After mixing evenly, it is pulverized by a superfine pulverizer, so that all ingredients can pass through the 80-mesh sieve;

[0027] C. The pulverized material is fed into the modem with 16kg, 93°C water vapor for 5 minutes, and then the raw material is granulated at a temperature of 102°C into the extruder granulator;

[0028] D. Dry the extruded feed pellets at 95°C.
