Embodiment 1

[0010] Weigh 45kg of flaxseed, 30kg of chitosan oligosaccharide, 20kg of L-carnitine and 5kg of hydroxymethionine, grind them into powder respectively, pass through a 120 mesh sieve, and then mix them evenly in a mixer, and make the coefficient of variation of the obtained mixture ≤5%, It is the feed additive capable of reducing the visceral fat content of grass carp of the present invention. Grass carp were cultured in the indoor recirculating culture system of four experimental sites in different regions, and the initial weights of the fish were: 8.68±0.75 g, 18.92±1.36 g, 51.63±2.61 g and 80.63±3.78 g. The feed additive that can reduce grass carp viscera fat content of the present invention is all not added in the feed that control group is used; Simultaneously common feed (equal protein level) is used as contrast, and each control group has 4 repetitions; 0.15% (mass percentage) of the product of the present invention, also set up 4 repetitions under each experimental grou...

Embodiment 2

[0012] Weigh 35kg of flaxseed, 35kg of chitosan oligosaccharide, 23kg of L-carnitine and 7kg of hydroxymethionine, grind them into powder respectively, pass through a 120-mesh sieve, and then mix them evenly in a mixer, and make the coefficient of variation of the obtained mixture ≤5%, It is the feed additive capable of reducing the visceral fat content of grass carp of the present invention. The field breeding experiments were carried out in three places in different regions, and the breeding experiments of fish (initial weight 31.63±2.15 g) in the three places were carried out in 4 ponds, and the average area of ​​each pond was 9 mu. The feed additives of the present invention that can reduce the visceral fat content of grass carp were not added to the feed used in the control group; at the same time, ordinary feed (equal protein level) was used as a control. Add 0.3% product of the present invention in the experimental feed. After a 60-day feeding experiment, the visceral ...

Embodiment 3

[0014] Weigh 42kg of flaxseed, 25kg of chitosan oligosaccharide, 25kg of L-carnitine and 8kg of hydroxymethionine, grind them into powder respectively, pass through a 120 mesh sieve, and then mix them evenly in a mixer, and make the coefficient of variation of the obtained mixture ≤5%, It is the feed additive capable of reducing the visceral fat content of grass carp of the present invention. Grass carp were cultured in the indoor recirculating culture system of four experimental sites in different regions, and the initial weights of the fish were: 8.68±0.75 g, 18.92±1.36 g, 51.63±2.61 g and 80.63±3.78 g.

Abstract

The invention relates to a feed additive capable of reducing the fat content of the grass carp viscus. The feed additive comprises the following ingredients in percentage by mass: 35 to 45 percent of flaxseed, 25 to 35 percent of chitosan oligosaccharide, 20 to 25 percent of L-carnitine and 5 to 8 percent of hydroxymethionine. The fat content of the grass carp viscus can be obviously reduced, thebody protein deposition rate is improved, the edible rate is improved by 14 to 23 percent, the resources of the used ingredients are stable, the price is low, and the production process is simple.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a feed additive capable of reducing the visceral fat content of grass carp. Background technique [0002] Grass carp is an excellent freshwater aquaculture species, and it is the second largest fish in the world, second only to silver carp. Grass carp is also the main economic aquaculture species in my country, accounting for about 21% of the total freshwater aquaculture. Because of its fast growth, delicious meat, rich and comprehensive nutrition, and good economic benefits, it is deeply loved by farmers and consumers. However, in recent years, due to the rapid development of high-density intensive breeding models, grass carp feeds are required to adopt high-energy and low-protein feed strategies; in addition, unreasonable or large-scale use of plant protein sources in feeds has negative effects on the physiological functions of grass carp hepatopancreas. influences. ...
