Abstract
The invention discloses a kind of feed preparation method of threonine chelated ferrous iron, this method belongs to feed additive field, and producing the raw material that the product uses includes: threonine, ferrous sulfate, 10% sodium hydrate aqueous solution；Product is made by techniques such as the chelatropic reaction of the production of aqueous solution, threonine and ferrous sulfate, separation drying, technological advantage is: the threonine chelated ferrous iron of industrialized production, simple process, manufacturing cost is low, it is easy to operate without increasing important equipment, it is easy to spread；Threonine chelated ferrous iron sufficiently plays the effect of growth of animal, iron is one of indispensable microelement in animal feed, during executing oxygen carrier and storage oxygen, iron plays highly important role, ferro element is with hematopoiesis function, the synthesis of hemalbumin, cytochromes and various enzymes is participated in, iron also starts shipment oxygen therapy and the effect of nutriment in blood and the absorptivity of threonine chelated rear animal greatly increases.
Description
Technical field
The invention belongs to feed additive fields, and in particular to a kind of preparation method of the threonine chelated ferrous iron 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 ferrous sulfate, and threonine is the second or of livestock and poultry
Three limiting amino acids have promotion growth, improve immunity function, lack threonine, and can lead to animal feed intake reduces, grows
It is obstructed, the symptoms such as efficiency of feed utilization decline, immunity function inhibit, and threonine is that animal itself cannot synthesize, but extremely need
The amino acid wanted can only be entered in animal body by feed, and addition threonine also can reduce tryptophan or methionine excessively causes
Growth inhibition.Trace elements iron be to the life of animal it is extremely important, iron is present among hemoglobin and myoglobins,
During they execute oxygen carrier and storage oxygen, iron plays highly important role, and ferro element is participated in hematopoiesis function
The synthesis of hemalbumin, cytochromes and various enzymes promotes growth；Iron also starts shipment oxygen therapy and the effect of nutriment in blood；
Iron 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 with threonine and ferrous chelate, produce what the product used
Raw material includes: threonine, ferrous sulfate, 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 ferrous iron of feed, it is characterized in that being made of following steps:
(1) threonine: ferrous sulfate: the ratio of water 19-21:11:68-70 in molar ratio is sent into chemical reaction kettle, keeps normal
Temperature starts blender, monitors pH value at any time, is 7.0-7.2, reaction time 0.8-1.0 with 10% sodium hydrate aqueous solution tune pH value
Hour.
(2) reactant is sent into centrifugal separator separation, removing the solid obtained after moisture removal is threonine chelated ferrous iron, will
Threonine chelated ferrous be sent into after drying machine sealing is dried 1.0-1.2 hours obtains finished product.
Threonine purity described in above-mentioned steps (1) is 90%.
Ferrous sulfate purity described in above-mentioned steps (1) is 70%.
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 ferrous iron of industrialized production, simple process, manufacturing cost is low, without increasing important equipment, operation side
Just, easy to spread；
(2) the feed palatability of product configuration is good, and absorptivity is high, easily transports, the threonine chelated ferrous effect to growth of animal
Sufficiently being played, iron is one of indispensable microelement in animal feed, during executing oxygen carrier and storage oxygen, iron
Highly important role is played, ferro element participates in the synthesis of hemalbumin, cytochromes and various enzymes with hematopoiesis function,
Iron also starts shipment oxygen therapy and the effect of nutriment in blood and the absorptivity of threonine chelated rear animal greatly increases.
