Embodiment 1

[0024] (1) Feed settings:

[0025]

[0026] Described fish meal is the white fish meal of American Seafood Company, purchased from Wuhan Gaolong Feed Co., Ltd.;

[0027] Described fish oil is Peruvian anchovy oil, purchased from Wuhan Gaolong Feed Co., Ltd.;

[0028] The vitamin premix is ​​(g / kg feed): vitamin A, 110; vitamin B1, 20, vitamin B2, 20; vitamin B6, 20; vitamin B12, 0.02; vitamin C, 100; vitamin D, 20; Vitamin E, 50; Vitamin K, 10; Folic Acid, 5; Calcium Pantothenate, 50; Inositol, 100; Niacin, 100; Biotin, 0.1; Cellulose, 645.2.

[0029] Described mineral salt premix is ​​(gram / kg feed): sodium chloride NaCl, 500; Magnesium sulfate heptahydrate MgSO 4 ·7H 2 O, 8155.6; Sodium dihydrogen phosphate dihydrate NaH 2 PO 4 2H 2 O, 12500.0; Potassium dihydrogen phosphate KH 2 PO 4 , 16000.0; Calcium hydrogen phosphate dihydrate CaHPO 4 2H 2 O, 7650.6; Iron sulfate heptahydrate FeSO 4 ·7H 2 O, 2286.2; Calcium lactate pentahydrate C 6 h 10 CaO 6 ·5H 2 O,...

Embodiment 2

[0043] (1) Feed formula

[0044] Its feed formula is identical with embodiment 1.

[0045] (2) Processing and preparation method

[0046] Its processing preparation method is identical with embodiment 1.

[0047] (3) Feeding method

[0048] Its feeding method is the same as that of Example 1, the cultured fish is bream, and the culture experiment lasts for 8 weeks.

[0049] (4) Breeding effect

[0050] The result is as follows:

[0051]

[0052] The results showed that: at the end of the 8-week test, the body weight, food intake, food intake rate and specific growth rate of bream in the experimental group were not significantly different from those in the control group; the feed efficiency (87.69%) of the experimental group was significantly higher than that of the control group (81.54%) ); at the end of the experiment, the fish body protein content, fat content, ash content and water content of the experimental group had no significant difference with the matched grou...

Abstract

The invention provides a preparation method and application of a feed for reducing fat deposition rate of freshwater fishes. The feed comprises white fish meal, casein, soybean oil, fish oil, corn starch, a vitamin premix, choline chloride, a mineral salt premix, carboxymethyl cellulose (CMC) and cellulose. Although the fish meal content is low, the feed conversion efficiency is still very high, and the breeding feed cost is reduced. The freshwater fish fed with the feed provided by the invention can effectively reduce the fat deposition rate of the fish body, reduce the liver-body ratio and is beneficial to liver health.

Description

[0001] This application is based on the divisional application of the invention patent application submitted on January 19, 2018 with the application number 201810055668.4 and the invention titled "A Feed for Improving Feed Conversion Efficiency and Protein Deposition Rate of Freshwater Fish and Its Application" . technical field [0002] The invention belongs to the field of aquaculture feed, and in particular relates to a preparation method and application of a feed for reducing the fat deposition rate of freshwater fish. Background technique [0003] China is the largest producer of aquatic products in the world, and the growing total of aquatic products mainly comes from aquaculture. According to the statistics of FAO (2006), China's aquaculture production accounts for about 70% of my country's total aquatic production, accounting for the world's About 70% of total aquaculture production. In 2016, the total output of aquatic products in my country was 691,250 tons, of wh...
