A feed for improving feed conversion efficiency and protein deposition rate of freshwater fish and its application

A technology for feed conversion efficiency and freshwater fish, which is applied in the field of feed to improve the feed conversion efficiency and protein deposition rate of freshwater fish. It can solve the problems of polluting aquaculture water, low feed conversion efficiency, and residual bait entering the water body, so as to reduce liver damage. Ratio, beneficial to the health of the liver and reducing the cost of breeding feed

[0022] (1) Feed settings:

[0023]

[0024] Described fish meal is the white fish meal of American Seafood Company, purchased from Wuhan Gaolong Feed Co., Ltd.;

[0025] Described fish oil is Peruvian anchovy oil, purchased from Wuhan Gaolong Feed Co., Ltd.;

[0026] Described vitamin premix is ​​(gram / kg feed): vitamin A, 110; Vitamin B 1 , 20, vitamin B 2 , 20; Vitamin B 6 , 20; Vitamin B 12 , 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.

[0027] 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 2H2O, 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...

Embodiment 2

[0041] (1) Feed formula

[0042] Its feed formula is identical with embodiment 1.

[0043] (2) Processing and preparation method

[0044] Its processing preparation method is identical with embodiment 1.

[0045] (3) Feeding method

[0046] Its feeding method is the same as that of Example 1, the cultured fish is bream, and the culture experiment lasts for 8 weeks.

[0047] (4) Breeding effect

[0048] The result is as follows:

[0049]

[0050] 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 discloses a feed for improving feed conversion efficiency and protein deposition rate of freshwater fish and its application. The feed includes: white fish meal, casein, soybean oil, fish oil, cornstarch, vitamin premix, and chole chloride Alkali, mineral salt premix, CMC (hydroxymethylcellulose) and cellulose. Although the feed of the present invention has a low content of fishmeal, the feed conversion efficiency is still very high, which reduces the cost of aquaculture feed, and the freshwater fish fed with the feed provided by the present invention can effectively reduce the fat deposition rate of the fish body and reduce the liver-to-body ratio. Good for liver health.

Description

technical field [0001] The invention belongs to the field of aquaculture feed, in particular to a feed for improving feed conversion efficiency and protein deposition rate of freshwater fish and an application thereof. Background technique [0002] 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 which the aquaculture output was 51.4239 million tons, and the freshwater aquaculture output was 31.7926 million tons, accounting for 61.82% of the total aquaculture output (China Fishery Statistical Yearbook, 2017). The rapid development of the aquaculture industry is highly dependent on the development of the ...
