Problems solved by technology

At present, most of the artificial cultured salmon are fed with fresh miscellaneous fish or chilled fish, but natural bait is generally difficult to meet the supply. When the supply of chilled fish or fresh miscellaneous fish is insufficient in actual production, some farmers use The feed feeding of other fish species has become the biggest limiting factor for the expansion of salmon production and the promotion of large-scale farming
However, the use of chilled fis...

Embodiment 1

[0022] Weigh 30 kg of commercially available fish meal, 20 kg of cottonseed protein, 10 kg of fermented soybean meal, 10 kg of brewer's yeast, 5 kg of cottonseed meal and 5 kg of rapeseed meal, put them into a coarse grinder, and crush them to obtain aniseed ingredients; 20 kilograms of commercially available high-gluten flour, 2.0 kilograms of calcium dihydrogen phosphate, 1.5 kilograms of vitamin and mineral salt mixture, 1.5 kilograms of choline chloride, and 200 ppm of DMPT are put into a superfine pulverizer together, and superfine pulverization can pass through 100 Mesh sieve powder, then move the powder into the modem, add water, the amount of water added is 1 / 4-5 of the total weight of the powder, stir evenly, and prepare under 90 ° C steam for 4-6 minutes. Finally, extruding and puffing granulation is carried out at 100°C to obtain puffed wet granules; the puffed wet granules are put into a horizontal drying box, and dried at 75°C until the puffed granules have a moist...

Embodiment 2

[0024] It is basically the same as Example 1, except that 40 kilograms of fish meal, 20 kilograms of cottonseed protein, 10 kilograms of fermented soybean meal, 10 kilograms of beer yeast, 5 kilograms of cottonseed meal and rapeseed meal are crushed into large ingredients, and then mixed with high-gluten flour 10 kilograms kg, 2.0 kg of calcium dihydrogen phosphate, 1.0 kg of vitamin and mineral salt mixture, 1.5 kg of choline chloride, and 150 ppm of dimethyl-β-thiatin propionate are superfinely pulverized together into powder.

Embodiment 3

[0026] It is basically the same as Example 1, except that 50 kilograms of fish meal, 15 kilograms of cottonseed protein, 5 kilograms of fermented soybean meal, 10 kilograms of brewer's yeast, 2.5 kilograms of cottonseed meal and rapeseed meal are pulverized into large ingredients, and then mixed with high-gluten flour 10 kilograms kg, 2.0 kg of calcium dihydrogen phosphate, 1.5 kg of vitamin and mineral salt mixture, 1.5 kg of choline chloride, and 100 ppm of dimethyl-β-thiatin propionate are superfinely pulverized together into powder.

Abstract

The invention discloses a complete extruded formula feed for Hucho taimen and a preparation method thereof. The complete extruded formula feed is made from the following raw materials: fish meal, cottonseed protein powders, fermented bean cake, bread flour, beer yeast, calcium dihydrogen phosphate, a vitamin-mineral salt mixture, choline chloride, dimethylpropiothetin (DMPT), or a cotton cake/rape cake mixture, wherein the cotton cake/rape cake mixture is composed of cotton cake and rape cake at a weight ratio of 1:1. The preparation method of the complete extruded formula feed for Hucho taimen comprises the steps as follows: roughly grinding large-sized raw materials to coarse powders, mixing all materials, micronizing to powders which can pass through a 100-mesh sieve, compounding, extruding to make pellets, and oven-drying. The preparation method is simple and practical and is favorable to industrial production. The complete extruded formula feed for Hucho taimen has the advantages of good palatability, high domestication speed, lower feed coefficient and good stability.

Description

technical field [0001] The invention relates to an artificial feed for fish, in particular to a full-price puffed compound feed for salmon and a preparation method thereof. Background technique [0002] Jero salmon is a cold-water freshwater carnivorous fish, mainly distributed in northern Asia. Zheluo salmon are ferocious and large in size. They prey on fish and frogs, snakes, rodents and birds that live in water. Zheluo salmon is delicious, tender and nutritious. It is a high-quality cold-water fish with high protein and low fat. It is also a special product in alpine regions and is a precious food in the production area. At present, most of the artificial cultured salmon are fed with fresh miscellaneous fish or chilled fish, but natural bait is generally difficult to meet the supply. When the supply of chilled fish or fresh miscellaneous fish is insufficient in actual production, some farmers use The feeding of other fish species has become the biggest limiting factor f...
