Abstract
The invention discloses a sulfur compensating agent which release sulfur slowly and the method for preparing the same and the usage. The product takes hydrotalcite as carrier, with the sulfate radical proportion in total anion in hydrotalcite interlayer being 80-100%. The process comprises: inserting the sulfate radical into hydrotalcite interlayer by making use of the interlayer assembling property of hydrotalcite, or calcining the hydrotalcite to 450-550 Deg C to get bimetallic oxide, then carrying sulfate radical by using the property of bimetallic oxide adsorbing anion. The hydrotalcite can release sulfur slowly because of the features it possesses: bio-availability, compatibility to gastrointestinal tract mucosa, commutativity between layers, high surface activity and large specific surface area. The product can be used for sulfur compensation for cow, sheep, poultry and aquatic creature and can also improve the quantity and quality of wool and rabbit hair.
Description
Technical field
The present invention relates to a kind of sulfur supplementary agent and preparation method and purposes of controlled release type sulphur.
Background technology
Sulphur is the essential nonmetalloid of organism, and in distribution each cell in animal body, mainly the form with organic sulfur is present in methionine, cystine, the cysteine.In addition, also be present in chondroitin sulfate and mucoitinsulfuric acid in biotin, thiamine, the mucopolysaccharide, and in heparin, coacetylase, fibrinogen and the sweet phthalein of paddy Guang.Also contained element sulphur in the keratin such as the quilt hair of animal, hoof tips, angle.Sulphur in the various in vivo tissues all exists with the form of sulfate or sulfuric acid ester, comprising chondroitin, cholyltaurine, heparin and sulfate.
Sulphur participates in synthetic rumen microorganism mycoprotein; Participate in the biosynthesis of keratin protein; Sulphur compound is the activator of some enzyme (as dehydrogenase and esterase), participate in the synthetic of body protein and lactoprotein, and fat metabolism and carbohydrate metabolism, be present in polypeptide chain, connect collagen and connective tissue with the disulfide bond form, can also participate in acid-base balance and detoxification processes.Sulphur occupies critical role in ruminant animal nutrition, the productivity that promotes ruminant to grow and to improve ruminant is had crucial meaning.In rabbit, wool fiber, constitute between the peptide chain of hair (suede) protein and be coupled to netted big molecule by disulfide bond, sat linkage and hydrogen bond, wherein the disulfide bond connection effect that is provided by cystine is the strongest.Sulphur plays an important role to the chemical stability and the steric configuration of rabbit, wool (suede) protein molecule, and the high sulfur content and the disulfide bond structure of rabbit, wool (suede) are the material bases of physicochemical properties such as rabbit, wool.Therefore, sulphur has material impact to textile performances such as the elasticity of rabbit, wool (suede) output and hair (suede), intensity.
Under the current raising condition of China, the protein of livestock and poultry and the main source of energy or plant feed, but the amino acid contained and inorganic sulfide compound of plant feed can not satisfy the needs of body far away, the contents of essential amino acids that can supply with in the plant feed lacks 30%～40% than requirement, and wherein sulfur-containing amino acid especially needs to replenish.Therefore the sulfur additives of seeking to suit has important and practical meanings to the production performance that improves livestock and poultry.
At present, adopt artificial sulfur-containing amino acid that synthesizes and sulfate supplementary source usually as sulphur.The absorption of sulphur is different with the difference of sulfur-containing compound kind.In general, tiring of organic sulfur source is higher than the inorganic sulfur source, and when with methionine during as evaluation criterion, other sulphur sources especially inorganic sulfur source relative potency are very low.Pour into methionine (2g/d) at cud and abomasum respectively to sheep by stages, find that the cud perfusion makes production of wool improve 28%, the wool sulfur content has improved 4.5%; And the abomasum perfusion, production of wool has improved 68%, and the wool sulfur content has improved 19.7%.As seen the degradation of rumen microorganism has reduced the utilization ratio of perfusion methionine, and in order to improve the biological value of sulfur-containing amino acid, people have transferred to research emphasis on the rumen-bypass amino acid.Methionine hydroxy analog (MnA), methionine metal complex and hydroxy analogs thereof can pass through cud safely, but its cost is higher.
The control slow-released system has selectivity and controllability to release position, speed and the mode of medicine, agricultural chemicals, fertilizer, spices, can realize the target transmission and the control slowly-releasing of object, improve its utilization rate and action effect, the research and the application of control slow-releasing system will bring new technological revolution to relevant industries.The control slow release method is also representing great application prospect and theory significance aspect the research and development of feed addictive, it can promote the high performance and the environmental friendlinessization of product, will provide material and technical guarantee for sustainable development of animal husbandry on new level.
The key of control slow release method is the selection of controlled release carrier.Hydrotalcite (Hydrotalcites, or Layered DoubleHydroxides, LDHs) be the anionic inorganic functional material, possess the Modulatory character of laminate chemical composition, leafing subcategory and quantity, crystallite dimension and distribution thereof on the structure, have purposes widely at aspects such as catalysis, ion-exchange, absorption, chemical industry.In recent years, hydrotalcite has had new application at aspects such as biological medicines, and hydrotalcite is realized commercialization rapidly as the specific drug of treatment stomach trouble in Europe.Performance that the intercalation that utilizes hydrotalcite to have is assembled and good biocompatibility, its transport vehicle as the bio-pharmaceutical molecule had very high using value, hydrotalcite is considered to the spacetabs type carrier of a class formation and mechanism of action novelty, more and more is subjected to researcher's extensive concern.
