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, the body 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
The present invention relates to the animal-breeding technical field, particularly relate to a kind of feed addictive that can reduce the grass carp harslet fat content.
Background technology
Grass carp is a kind of good freshwater aquiculture kind, is second largest fish of output in the world, is only second to silver carp.Grass carp is also China's Main Economic breed variety, accounts for 21% of freshwater aquiculture total amount.Delicious, nutritious and comprehensive because of fast growth, meat flavour, good in economic efficiencyly liked by numerous culturists and consumer.But in recent years, due to the fast development of high density culture pattern, require feed of grass carp to adopt the feed strategy of the low albumen of high-energy; In addition, in feed, unreasonable or a large amount of uses of plant protein source bring negative effect to the physiological function of grasscarp liver.These factors cause the grass carp harslet fat deposition to increase, and affect efficiency of feed utilization, have restricted the growth of grass carp, reduce again edible ratio and the quality of grass carp.Reducing the aquiculture animal visceral adipose is to improve its important channel to nutrient utilization.Therefore, a kind of feed addictive that can effectively reduce the cultured fishes visceral adipose of exploitation is an important step that improves the fish culture benefit.There is no so far the correlative study report.
Summary of the invention
The purpose of this invention is to provide a kind of feed addictive that can reduce the grass carp harslet fat content, it not only can promote nutrient digestion, alleviate burden of liver, can also effectively improve grass carp to reasonable utilization and the distribution of nutriment, improve feed efficiency, keep the sustainable development of grass carp aquaculture.
A kind of feed addictive that can reduce the grass carp harslet fat content of the present invention, its component and quality percentage composition are as follows:
Linseed 35-45%, chitosan oligosaccharide 25-35%, l-cn 20-25%, hydroxy methionine 5-8%.
The present invention is a kind of, and to reduce the preparation method of feed addictive of grass carp harslet fat content simple: take each component, the difference grinds, cross 120 mesh sieves, then mix in mixer, make the coefficient of variation of gained mixture≤5%, be the feed addictive of reduction grass carp harslet fat content of the present invention.
A kind of using method that can reduce the feed addictive of grass carp harslet fat content of the present invention is that as the preparing grass carp feed additive use, addition is the 0.15-0.30% of feeding quality.
A kind of feed addictive that can reduce the grass carp harslet fat content of the present invention has following advantage: can obviously reduce the grass carp harslet fat content, increase the deposition of body protein, improve edible ratio 14-23%; Raw materials enjoy stable sources used, cheap, production technology is simple.
The specific embodiment
Embodiment 1:
Take linseed 45kg, chitosan oligosaccharide 30kg, l-cn 20kg and hydroxy methionine 5kg, grinds, cross 120 mesh sieves respectively, then mixes in mixer, and make the coefficient of variation of gained mixture≤5%, be the feed addictive that can reduce the grass carp harslet fat content of the present invention.Carry out the cultivation of grass carp everywhere in test site indoor circulation cultivating system in zones of different respectively, the initial weight of fish is respectively: 8.68 ± 0.75 g, 18.92 ± 1.36 g, 51.63 ± 2.61 g and 80.63 ± 3.78 g.All do not add the feed addictive that can reduce the grass carp harslet fat content of the present invention in the feed that control group is used; Simultaneously normal diet (waiting protein level) in contrast, each control group is divided into 4 repetitions; All add the 0.15%(mass percent during experimental group is feeds utilized) product of the present invention, each experimental group is divided into 4 repetitions equally.After the raising experiment of 60 days, the visceral adipose of the grass carp of the experiment feed of feeding everywhere is significantly lower than control group and commercial feed group, and the body protein deposition improves 8-15%, and edible ratio improves 16-21%.
Embodiment 2:
Take linseed 35kg, chitosan oligosaccharide 35kg, l-cn 23kg and hydroxy methionine 7kg, grinds, cross 120 mesh sieves respectively, then mixes in mixer, and make the coefficient of variation of gained mixture≤5%, be the feed addictive that can reduce the grass carp harslet fat content of the present invention.Carry out the land for growing field crops culture experiment at zones of different three places respectively, the culture experiment of three place fishes (initial weight 31.63 ± 2.15 g) carries out on 4 mouthfuls of pools respectively, and the average area on every mouthful of pool is 9 mu.All do not add the feed addictive that can reduce the grass carp harslet fat content of the present invention in the feed that control group is used; Simultaneously with normal diet (waiting protein level) in contrast.Add 0.3% product of the present invention in the experiment feed.After the raising experiment of 60 days, the visceral adipose of grass carp is significantly lower than control group and commercial feed group, and the body protein deposition improves 9-17%, and edible ratio improves 15-22%.
Embodiment 3:
Take linseed 42kg, chitosan oligosaccharide 25kg, l-cn 25kg and hydroxy methionine 8kg, grinds, cross 120 mesh sieves respectively, then mixes in mixer, and make the coefficient of variation of gained mixture≤5%, be the feed addictive that can reduce the grass carp harslet fat content of the present invention.Carry out the cultivation of grass carp everywhere in test site indoor circulation cultivating system in zones of different respectively, the initial weight of fish is respectively: 8.68 ± 0.75 g, 18.92 ± 1.36 g, 51.63 ± 2.61 g and 80.63 ± 3.78 g.All do not add the feed addictive that can reduce the grass carp harslet fat content of the present invention in the feed that control group is used; Simultaneously normal diet (waiting protein level) in contrast, each control group is divided into 4 repetitions; All add the 0.2%(mass percent during experimental group is feeds utilized) product of the present invention, each experimental group is divided into 4 repetitions equally.After the raising experiment of 60 days, the visceral adipose of the grass carp of the experiment feed of feeding everywhere is significantly lower than control group and commercial feed group, and the body protein deposition improves 8-16%, and edible ratio improves 18-21%.
