Embodiment 1

[0019] An extruded mixed feed for grass crucian carp, comprising the following components by weight: 5 kg of fermented soybean meal, 25 kg of rapeseed meal, 10 kg of coconut meal, 10 kg of palm meal, 5 kg of corn DDGS, 5 kg of kelp residue, and secondary powder 33 kg, 0.5 kg of calcium hydrogen phosphate, 2 kg of premix for omnivorous fish, 3 kg of fish oil, 0.5 kg of crystalline methionine, and 1.0 kg of crystalline lysine.

[0020] The preparation method of the above-mentioned grass crucian carp polyculture extruded feed comprises the following steps:

[0021] A, take each component by weighing according to above-mentioned formula and mix evenly;

[0022] B, the above-mentioned mixture is pulverized, so that all ingredients can pass through a 50-mesh sieve;

[0023] C. The pulverized material is fed into the modem with water vapor with a total mass of 14kg and 95°C for 5 minutes, and then the raw material enters the extrusion granulator at a temperature of 98°C for granulat...

Embodiment 2

[0027] A polyculture extruded feed for grass crucian carp, including the following components by weight: 15 kg of fermented soybean meal, 30 kg of rapeseed meal, 3 kg of coconut meal, 5 kg of palm meal, 4 kg of corn DDGS, 3 kg of kelp residue, and secondary powder 34.7 kg, 0.5 kg of calcium hydrogen phosphate, 2 kg of premix for omnivorous fish, 2 kg of fish oil, 0.3 kg of crystalline methionine, and 0.50 kg of crystalline lysine.

[0028] The preparation method of the above-mentioned grass crucian carp polyculture extruded feed comprises the following steps:

[0029] A, take each component by weighing according to above-mentioned formula and mix evenly;

[0030] B, above-mentioned mixture is pulverized, makes all ingredients all can pass through the sieve of 60 meshes;

[0031] C. The pulverized material is fed into the modem with water vapor with a total mass of 15 kg and 98°C for 6 minutes, and then the raw material is granulated at a temperature of 102°C into an extrusion...

Abstract

The invention discloses a grass carp and crucian carp polyculture expanded feed and a preparation method thereof. The feed comprises the following components in percentage by weight: 5 to 15 percent of fermented soybean meal, 20 to 30 percent of rapeseed meal, 3 to 10 percent of coconut meal, 5 to 10 percent of palm kemel cake, 4 to 9 percent of distillers dried grains with soluble (DDGS), 3 to 9 percent of kelp residues, 15 to 40 percent of wheat middling, 0.5 to 1 percent of calcium hydrophosphate, 1 to 2 percent of premix for omnivorous fish, 1 to 3 percent of fish oil, 0.2 to 0.5 percent of crystal methionine, and 0.5 to 1.0 percent of crystal lysine. The polyculture expanded feed can float on the water surface, so that enough ingestion time is provided for cultured fish, the waste of the feed is reduced, meanwhile, the feed expanded at high temperature has high stability in water and difficultly pollutes culture water.

Description

technical field [0001] The invention relates to a fish feed, in particular to a mixed cultured puffed feed for grass crucian carp and a preparation method thereof. Background technique [0002] Allogenetic gibel crucian carp and grass carp are important freshwater aquaculture species in my country. In order to give full play to the production potential of water bodies, according to the different ecological niches of gibel crucian carp and grass carp, many farmers in Jiangsu and Zhejiang adopt the mixed culture of grass carp and crucian carp, and have achieved good breeding benefits. [0003] The quality of feed is one of the key technologies for the development of freshwater aquaculture. For the polyculture mode of freshwater fish, someone has designed the compound feed of fresh water polyculture fish, discloses a kind of compound feed of fresh water polyculture fish as Chinese invention patent application CN1947556A, is mainly aimed at green, grass, silver carp, bighead fo...
