Compound feed for seawater white pomfret
[technical field]
The present invention relates to a kind of feed, relate in particular to a kind of compound feed for seawater white pomfret.
[background technology]
The growth of seawater butterfish is fast, and is disease-resistant strong, belongs to ominivore-fish, and its delicious meat is of high nutritive value, and is subjected to liking of consumers in general deeply, along with the raising of people's living standard, to the also constantly increase of demand of seawater butterfish.The aquaculture of seawater white pomfret becomes a kind of industry of emerging development, and it is particularly urgent that the development of compound feed for seawater white pomfret also becomes.Seldom there is compound feed for seawater white pomfret to sell in the market, the raiser replaces with other marine fish feeds the breed of seawater butterfish is many, or the iced trash fish of throwing something and feeding, this has caused the serious wasting of resources and environmental pollution, also make the seawater butterfish can not absorb reasonable sufficient nutrition composition, can not bring into play its good growth performance, direct losses raiser's economic benefit.The raiser needs a kind of reasonable mixture ratio, and is balanced in nutrition, can satisfy the mixed feed of seawater butterfish growth.
[summary of the invention]
The purpose of this invention is to provide a kind of reasonable mixture ratio, balanced in nutrition, can satisfy the compound feed for seawater white pomfret of seawater butterfish growth.
A kind of compound feed for seawater white pomfret of the present invention, form by following raw material and quality percentage composition thereof: steam fish meal 28~37%, fermented bean dregs 25~35%, peanut meal 4~10%, cuttlefish cream 3~5%, Strong flour 15~25%, shrimp head powder 3~5%, fish oil 1~2%, vegetable oil 1~2%, composite mineral matter 0.2~0.5%, B B-complex 0.1~0.2%.
Wherein preferred raw material and quality percentage composition thereof consist of: steam fish meal 30~35%, fermented bean dregs 28~31%, peanut meal 4~10%, cuttlefish cream 3~5%, Strong flour 17~22%, shrimp head powder 3~5%, fish oil 1~2%, vegetable oil 1~2%, composite mineral matter 0.2~0.5%, B B-complex 0.1~0.2%.
Most preferred raw material of the present invention and quality percentage composition thereof consist of: steam fish meal 31%, fermented bean dregs 29%, peanut meal 8.5%, cuttlefish cream 3%, Strong flour 20%, shrimp head powder 4.9%, fish oil 1.5%, vegetable oil 1.5%, composite mineral matter 0.5%, B B-complex 0.1%.
Wherein, described steam fish meal is commercially available, and its parameters index is: albumen: 65--66%; Fat: below 12%; Moisture: below 10%; Free fatty: below 10%; Sand and salt: 5% (its medium sand is below 2%), ash: below 17%; VBN/TVBN:120Mg/g.
Described Strong flour is that protein content is at the flour more than 11.5%.
Composite mineral matter and B B-complex can be selected commercially available composite mineral matter and B B-complex, also can get 50g MgSO

7The IU vitamin A, 150g vitamin E, 20g vitamin K, 12.5g biotin, 5g folic acid, the 104g inositol, 60g nicotinic acid, 50g calcium pantothenate, 12g vitamin B1, the 15g vitamin B2, the 15g vitamin B6, the thin wheat skin of 530.5g, mixing and stirring is made the 1000g B B-complex.
The preparation method of a kind of compound feed for seawater white pomfret of the present invention is:
(1) takes by weighing raw material;
(2) pulverize fermented bean dregs, peanut meal, make it can be by the sieve of 2mm;
(3) fermented bean dregs after will pulverizing and other components in peanut meal and the raw material mix;
(4) raw material after will mixing is pulverized once more, makes all components can both be by 80 purposes sieve;
(5) material after pulverizing feeds 90 ℃ modified 5 minutes of steam, and raw material is granulated down at 85 ℃, and made granular size is 1-3mm;
(6) 100 ℃ of oven dry down.
The modulation step of step (5) is preferably finished in modulator; The granulation step of step (5) is preferably finished in the extrusion granulator.
Mixed feed of the present invention is used for directly throwing something and feeding white pomfret, and feeding volume needs to decide according to the size and the cultivation density of white pomfret, and a general day feeding volume is 3.5% of a white pomfret body weight.
Carried out 5 months by a definite date seawater white pomfret culture experiment in May, 2008 in national 863 sea-farming seed engineerings bases, south (Zhanjiang Evergreen Southern Ocean Technology Co., Ltd.).Result of the test shows, use feed of the present invention after, the orbfish fry of 50g cultures that weight can reach 800 grams after 5 months, feed coefficient is below 1.5.
This feed is according to the growth characteristics of seawater white pomfret and nutritional need is refining forms, comprehensive nutrition, and attractant is strong, can at utmost discharge the growth potential of seawater orbfish, this feed has added several mineral materials and vitamin, can improve intestinal immunological barrier, strengthens immunologic function.Compound feed for seawater white pomfret of the present invention has following advantage:
(1) comprehensive nutrition promotes growth; (2) strengthen immunity, resisting stress; (3) protection fish body enteron aisle prevents that disease from taking place; (4) feed coefficient is low, the digestibility height; (5) the feed water stability is good, is difficult for polluting breeding water body water quality.
