Abstract

The invention provides a compound feed capable of improving the body color of golden pomfret. The compound feed comprises a base feed and a coloring agent, wherein the coloring agent consists of pine needle leaves, coprinus comatus, cape jasmine fruit and wolfberry in the weight ratio of 3-5:1-3:1-2:0.5-2. According to the compound feed, the four components of the pine needle leaves, the coprinus comatus, the cape jasmine fruit and the wolfberry are added to the conventional feed, so that the pigment deposition of the golden pomfret can be improved remarkably and the golden pomfret can reach a natural body color; the feed also helps to improve the survival rate of the golden pomfret, increase non-specific immunity, improve the growth rate of the golden pomfret, and reduce feed coefficient.

Description

A kind of mixed feed that can improve golden butterfish body colour

Technical field

The invention belongs to technical field of aquaculture, be specifically related to a kind of mixed feed that can improve golden butterfish body colour.

Background technology

Gold butterfish, formal name used at school egg-shaped pompano (Trachinotusovatus), is famous and precious edible fishes, has higher economic worth.Gold butterfish is in high density intensive culture process, culture-cycle shortens, nutriment is mainly derived from mixed feed, in addition in feed, effective pigment source is less and unstable, gold butterfish can not obtain sufficient natural colouring matter source, cause fish body body colour bright-coloured not as good as naive individuals, have a strong impact on the value of product.At present in order to improve the body colour of golden butterfish, usually in golden butterfish feed, add synthetic food color, these Prof. Du Yucang speed can not be got rid of external by the biodegradation of fish body self or be converted into innocuous substance, after people is edible, by crisis human health.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of natural, green, safe a kind of mixed feed that can improve golden butterfish body colour.

Technical scheme provided by the invention is a kind of mixed feed that can improve golden butterfish body colour, and it comprises basal feed and colouring agent, and described colouring agent is made up of pine needle, coprinus comatus, cape jasmine and the fruit of Chinese wolfberry, and its weight ratio is 3 ~ 5:1 ~ 3:1 ~ 2:0.5 ~ 2.

Pine needle is the needle of Siberian cedar, black pine, Chinese pine, Korean pine, Huashan pine, pinus yunnanensis, pinus khasys, masson pine etc. in Pinaceae pine genus plant.

Cape jasmine (formal name used at school: GardeniajasminoidesEllis) is called: Yellow Fructus Gardeniae, mountain Cape jasmine, white toad are the fruits of madder wort cape jasmine.

Coprinus comatus, also known as coprinus comatus, Classification system is Copyindscomatus (MUII.Fr) Gray.

Basal feed is generally made up of fish meal, dregs of beans, the dish dregs of rice, cotton dregs, peanut meal, secondary powder, flour, rice bran, rape oil, mineral substance premix, calcium dihydrogen phosphate and salt, those skilled in the art suitably can increase and decrease component according to prior art, and the proportioning of each component is also ordinary skill in the art means.

As preferably, the weight ratio of pine needle, coprinus comatus, cape jasmine and the fruit of Chinese wolfberry is 4:2:1.5:1.5.

The weight ratio of described colouring agent and basal feed is 0.1 ~ 0.2:100.

Compared with prior art, the present invention has following beneficial effect:

1) in conventional feed, add the survival rate that pine needle, coprinus comatus, cape jasmine and the fruit of Chinese wolfberry four kinds of components contribute to golden butterfish, and reduce feed coefficient.

2) interpolation of pine needle, coprinus comatus, cape jasmine and the fruit of Chinese wolfberry four kinds of components can significantly improve golden butterfish tissue digestion enzymatic activity, strengthens non-specific immunity, improves the golden butterfish speed of growth.

3) color additive of the present invention is well below conventional levels, can significantly improve golden butterfish pigment deposition, makes golden butterfish reach natural body colour, and natural, environmental protection, health.

Detailed description of the invention

The present invention is further elaborated for following specific embodiment, but not as a limitation of the invention.

Experimental example

1, select health, body weight is raised in recirculating aquaculture laboratory at golden butterfish 4000 tail of 5 ± 0.1g, be divided into 4 groups at random, often organize 1000 tails, be respectively control group, experimental group 1 ~ 3.Control group is thrown and is raised the basal diet of embodiment 1, and experimental group 1 ~ 3 is thrown something and fed the mixed feed that embodiment 1 ~ 3 is made respectively.Every day, throwing raised 3 times, and the time is respectively 6:30,13:00 and 18:00, and throwing the rate of raising is 3%, and ingest time controls at 20 ~ 30min, and fish is had enough, as far as possible not residual bait, adopted circular flow water system to raise, every day more than oxygenation 10h.Experimental session average temperature is 24 DEG C, and breeding cycle is 90d.

2.1 production performance index determinings

Experiment claims fish initial weight, experimental session record food ration when starting, and it is heavy that experiment terminates rear title fish end, and observe fish body colour pool, and record food ration and death condition, be calculated to be motility rate, rate of body weight gain and feed coefficient, concrete condition is in table 1.

Survival rate (%)=test last fish body sum/experiment just fish body sum × 100;

Rate of body weight gain (%)=(fish body end weight-fish body initial weight)/fish body initial weight × 100;

Feed coefficient=Feed consumption/(fish body end weight-fish body initial weight).

2.2 physiological index determining

Random choose 3 ~ 4 tail fish from each group, arteria caudalis gets blood, and refrigerated centrifuge (1500r/min, 10min) collects serum, is placed in 0 DEG C of refrigerator and preserves; Fish solution is taken liver pancreas weigh, volume ratio 1:9 carries out ice bath homogenate by weight, centrifugal (3000r/min, 10min), and collection supernatant is put into 0 DEG C of refrigerator and preserved, and completes mensuration in 48h.

1) liver pancreas ALT vitality test

Liver pancreas ALT activity is carried out according to kit description, result adopts Ka Menshi unit meter (KU), Ka Menshi unit definition for: 1ml serum, reactant liquor total capacity 3ml, wavelength 340nm, 1cm optical path, 25 DEG C, the pyruvic acid produced in 1min, make NADH be oxidized to NAD ⁺and cause absorbance decline 0.001 to be a unit.

Liver pancreatic tissues homogenate crude protein content measures ginseng coomassie brilliant blue, and determination step carries out according to kit description.

2) activity of SOD in serum measures

Adopt xanthine oxidase to measure activity of SOD in serum, SOD vigor is defined as: when in every ml reactant liquor, SOD inhibiting rate reaches 50%, corresponding SOD amount is 1 SOD unit of activity (U).Determination step carries out according to kit description.

3) serum LSZ determination of activity

Adopt blank method, determination step is undertaken by kit description.
