Description
Technical field
The present invention relates to a kind of chromium supplementing feed additive having and preparation and using method of carried type, super-fine chromium, is chromium supplementing feed additive having and the preparation and the using method of the ultra-fine chromium powder of a kind of porous mineral material load specifically.
Background technology
Trace element chromium is a kind of transition metal of being found first by french chemist (Louis Vanquelin) in 1797.Nineteen fifty-seven Mertz and Schwarz propose glucose tolerance factor first, and (nineteen fifty-nine confirms that chromium is rat growth and the indispensable element of keeping GTF for glucose tolerance factor, GTF) hypothesis.The biological function of chromium:
(1) immunocompetence of raising animal: can stimulate lymphocyte after in feed, adding chromium, thereby produce the immunological stress product, improve the immunity of animal.
(2) improve the animal carcass quality: studies show that in a large number, mend chromium and can improve lean meat percentage, reduce fat, improve carcass quality.Lindemann etc. (1993) report: to store pig additional 0.1 or 0.2mg/kg chromium (methylpyridine chromium), eye muscle area and lean meat percentage improve 18% and 7% respectively, and protein content increases, and fat content reduces, and the tenth rib place thickness of backfat descends 21%.Chromium is that the important component part as insulin GTF (GTF) increases the sensitiveness to insulin, thereby reaches the effect that reduces serum insulin.The effect of insulin also has the fat of promotion synthetic except that reducing blood sugar, suppresses fat-splitting effect.
(3) cholesterol in the reduction egg: according to research reports, mend chromium and can improve the living fat speed of laying hen (comprising that aliphatic acid and glycerine are synthetic); Strengthen production performance, improve the egg protein amount, reduce the laying hen blood cholesterol levels.Lien etc. (1996) report, 0.22,0.4,0.8mg/kg in coming carrier's product layer diets in vain, adds the Organic Chromium (methylpyridine chromium) of varying level:, can make the cholesterol level in the yolk reduce by 14%, 29% and 34% respectively, and little to the laying rate influence.Chi Xinliang (2000) research thinks that trivalent chromium can stimulate glycogen synthetase and insulin active, and with GTF performance biological effect, because chromium is the reinforcing agent of insulin, insulin can promote body fat to store, suppress the hydrolysis of depot lipid, make free aliphatic acid minimizing in the blood, cholesterol level also reduces thereupon, and the cholesterol level in the egg yolk is from chicken serum, so the cholesterol in the egg yolk also reduces thereupon.
Chromium supplementing agent commonly used has chromium chloride, methylpyridine chromium, nicotinic acid chromium, yeast chromium etc.Yet, all the biological effect of chromium powder is not studied both at home and abroad.Existing research report, copper powder, metal iron powder have biological effect; And their biological value is relevant with the granularity of powder.Zhao Qiuyan (2001) has summarized the influence of iron particle size to the relative biology utilization rate of iron powder in the food, the relative biology utilization rate of 10~20 μ m, 43 μ m, 147 μ m reduced iron powders is respectively 54%, 34% and 18%, shows that the granularity that reduces iron powder can significantly improve its biology utilization rate.Chinese patent (application number 03133894.1, Granted publication CN1194668C) discloses the application of a kind of copper nanoparticle as the preparation medicament for immunity enhancement.Studies show that in a large number that in recent years the simple substance selenium of particle diameter below 200 nanometers is compared with general simple substance selenium, and the variation of essence has taken place: take place " red shift " or " blue shift ", color shows as red or orange; Become from inertia and can directly efficiently remove free radical; From the inanimate object activity become efficiently, low toxicity.But along with copper powder, metal iron powder is equigranular reduces, its non-oxidizability also decreases, and the contradiction that therefore how to solve granularity and stability is a great problem in the superfine powder practical application.
Hard template method synthesis of nano structural system, be grow up the mid-90 in 20th century a kind of new technology of constructing nanostructured by self assembly, promptly utilize and have nanometer level microporous template (being commonly called as nano die), select suitable deposition technique, directly synthesis of nano structure in the micropore of template; Because nib pore size unanimity, the material of preparation has the mono-dispersed nano structure, and synthetic method is comparatively simple, and the material of preparation is applied to many aspects such as medicine release, photocatalysis, molecular separation and bioengineering and has extremely wide application prospect.
The porous mineral material is meant that those have the mineral of abundant structures duct or pore structure, comprises natural porous mineral material and artificial synthesizing porous mineral material.The porous mineral material comprises that mainly zeolite and correlation molecule sieve material, sepiolite group clay mineral, layer column type porous material (adobe material and porous laminated dihydroxylated thing (hydrotalcite) material) etc., can show the dimensional effect and the skin effect of portalling.The porous mineral material possesses even or approximate uniform duct, aperture and opening structure, and its nanochannel structure can be used as " miniature nano-reactor ", as carrier and the media of making the nanostructured assembled material.Utilize the porous mineral material as " microreactor of confinement " nano materials, the nano material of preparation has narrow grain size and distributes, and is expected to solve preferably nano particle and reunites and stability problem suitability for industrialized production.
