Abstract
The invention discloses a kind of feed preparation method of threonine chelated selenium, this method belongs to feed additive field, and producing the raw material that the product uses includes: threonine, selenium powder, 10% sodium hydrate aqueous solution；Product is made by techniques such as the chelatropic reaction of the production of aqueous solution, threonine and selenium powder, separation drying, technological advantage is: the threonine chelated selenium of industrialized production, simple process, manufacturing cost is low, easy to operate without increasing important equipment, easy to spread；Trace elements of selenium is extremely important to the life of animal, selenium is the active constituent for constituting glutathione peroxidase, it can prevent beta Cell of islet Oxidative demage, keep its function normal, promote sugared part metabolism, reduce the glucose and hemoglobin level in urine, it is that the absorptivity of one of indispensable microelement and threonine chelated rear animal greatly increases in animal feed.
Description
Technical field
The invention belongs to feed additive fields, and in particular to a kind of preparation method of the threonine chelated selenium of feed.
Background technique
Microelement is one of essential nutrient during growth of animal, and initial microelement is with inorganic salts
Form is introduced directly into feed, such as ferrous sulfate, although inorganic salts are water-soluble very well, in animal alimentary canal easily with feeding
Common phytate anion, oxalate anion form corresponding solubility very little by the intracorporal biochemical reaction form of animal in material
Salt, be not easy by intestinal absorption.With the development of feed industry, trace mineral supplement amino-acid trace element chelate etc. is gradually
It is developed, its feature is stable, efficient, small toxicity, and the absorption easy to digest in enteron aisle is conducive to growth of animal, energy
Prevent and treat trace element deficiency, improve the immunity of organisms of animal, and in feed nutrition composition using beneficial, it is also simultaneous
There is high-protein agent.The present invention is the chelate of threonine and selenium, and threonine is second or the third limitation of livestock and poultry
Acidic amino acid, have promote growth, improve immunity function, lack threonine, can lead to animal feed intake reduction, growth retardation,
Efficiency of feed utilization decline, immunity function such as inhibit at the symptoms, and threonine is that animal itself cannot synthesize, but highly desirable ammonia
Base acid, can only be entered in animal body by feed, and addition threonine also can reduce tryptophan or the excessive caused growth of methionine
Inhibit.Trace elements of selenium be to the life of animal it is extremely important, selenium be constitute glutathione peroxidase active constituent,
It can prevent beta Cell of islet Oxidative demage, keep its function normal, promote sugared part metabolism, reduce the glucose and blood red egg in urine
White level is that the absorptivity of one of indispensable microelement and threonine chelated rear animal greatly increases in animal feed.
Summary of the invention
Present invention mainly solves the problem of be to provide a kind of chelate with threonine and selenium, produce the original that the product uses
Material includes: threonine, selenium powder, 10% sodium hydrate aqueous solution.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of the threonine chelated selenium of feed, it is characterized in that being made of following steps:
(1) threonine: selenium powder: water in molar ratio 16-18:8:74-76 ratio be sent into chemical reaction kettle, the temperature remains within the normal range, opens
Dynamic blender, monitors pH value at any time, is 7.0-7.2, reaction time 0.8-1.0 hour with 10% sodium hydrate aqueous solution tune pH value.
(2) reactant is sent into centrifugal separator separation, removing the solid obtained after moisture removal is threonine chelated selenium, will be revived
Propylhomoserin chelating selenium obtains finished product after being sent into drying machine sealing drying 1.0-1.2 hours.
Threonine purity described in above-mentioned steps (1) is 90%.
Selenium powder purity described in above-mentioned steps (1) is 90%.
The drying temperature of drying machine described in above-mentioned steps (2) is 50 DEG C -60 DEG C.
The beneficial effects of the present invention are:
(1) the threonine chelated selenium of industrialized production, simple process, manufacturing cost is low, easy to operate without increasing important equipment,
It is easy to spread；
(2) the feed palatability of product configuration is good, and absorptivity is high, easily transports, and threonine chelated selenium fills the effect of growth of animal
Get performance, trace elements of selenium be to the life of animal it is extremely important, selenium is the work for constituting glutathione peroxidase
Property ingredient, it can prevent beta Cell of islet Oxidative demage, keep its function normal, promote sugared part metabolism, reduce glucose in urine and
Hemoglobin level is that the absorptivity of one of indispensable microelement and threonine chelated rear animal is big in animal feed
It is big to increase.
