Embodiment 1

[0026] A mixed feed for improving the body shape of grass carp and crucian carp, including compound premix and mixed feed, the compound premix includes the following raw materials in terms of weight percentage, vitamin premix 0.1-0.5%, trace element premix 0.2-2% %, choline chloride 0.1-0.3%, calcium dihydrogen phosphate 1.5-2.5%, compound enzyme preparation 0.1-0.5%, feed additive 0.1-0.5%, fermentation raw material 2-4%; compound feed preferably includes the following raw materials: Imported fish meal, soybean meal, rapeseed meal, cotton meal, secondary flour, wheat, rice bran, soybean oil, compound premix.

[0027] in:

[0028] The trace element premix is: 25% copper sulfate pentahydrate 0.3-1.0%, 30% ferrous sulfate monohydrate 10-30%, 34.5% zinc sulfate monohydrate 5-15%, 31.8% manganese sulfate monohydrate 2- 5%, 1% cobalt chloride 0.05-0.15%, 1% potassium iodide 1-5%, 1% sodium selenite 0.5-1.5%, 15% magnesium sulfate heptahydrate 10-30%, and the balance is medical sto...

Embodiment 2

[0072] Disclosed in this embodiment is a preparation method of a mixed feed for improving the body shape of grass carp and crucian carp. The production of compound feed comprises the following process steps:

[0073] A. Select imported fishmeal, soybean meal, rapeseed meal, cotton meal, secondary meal, wheat and rice bran according to the mass percentage, and after removing impurities, use a sieve crusher with an aperture of 1.0mm to pulverize;

[0074] B. After mixing the pulverized raw materials obtained in step A uniformly, the soybean oil, the compound premix and the uniformly mixed raw materials are mixed uniformly again to obtain a powdered compound feed;

[0075] C. Perform steam conditioning on the uniformly mixed powdered compound feed obtained in step B. The steam pressure is 0.25-0.4 MPa, the conditioning temperature is above 90°C, and the conditioning time is 60s, so that the powdered compound feed is steamed. The moisture content after conditioning is about 16%; ...

Abstract

The invention discloses a compound feed capable of improving body shape of grass carps and crucian carps and a preparation method thereof, and a mixed feed prepared by adopting the compound feed capable of improving body shape of the grass carps and the crucian carps. The compound feed capable of improving body shape of the grass carps and the crucian carps comprises the following raw materials inpercentage by weight: 2-8% of imported fish meal, 15-30% of soybean meal, 15-30% of rapeseed meal, 5-10% of cottonseed meal, 8-15% of middlings, 10-20% of wheat, 5-15% of rice bran, 1-3% of soybean oil, and 1-5% of a compound premix. The compound feed is capable of solving the problems of the grass carps and the crucian carps, namely short and fat body, high aquaculture feed cost, and low aquaculture benefits.

Description

technical field [0001] The invention belongs to the field of freshwater fish feed, and in particular relates to a compound feed for improving the body shape of grass carp and crucian carp, a preparation method thereof, and a mixed feed made by using the compound feed. Background technique [0002] After years of development, China's modern aquaculture industry has become a pivotal industry. Now, China's aquaculture production has reached 43 million tons, 50% of which are not dependent on feed, among which filter-feeding species, herbivorous species exceed 50%, plus a large number of omnivorous species, these three types account for all species 92% of the species, only 8% of the carnivorous species. China's aquaculture is low-trophic. We use very few fishery resources to raise a large amount of aquatic products. China consumes about 1.6 million tons of fishmeal every year, of which 1 million tons is imported, but since 2000, the amount of fishmeal imported by China has stop...
