Problems solved by technology

[0004] However, although the amino acid-complexed trace elements synthesized with high-priced lysine, methionine, glycine, etc. have high biological potency, their use costs are relatively high, especially in the current competitive feed market environment. The demand for cost of use is increasingly prominent

Abstract

The invention relates to a complex compound, in particular to a complex compound obtained by complexing clacium twice, a preparation method and application of the complex compound in an animal feed additive. According to the complex compound obtained by complexing calcium twice, firstly the calcium is complexed with malt sugar, then calcium ions in waste liquid and filter residues are complexed through amino acids to guarantee that a calcium reaction is complete, and finally, a malt sugar calcium product is mixed with an amino acid complexing calcium product. The complex compound obtained by complexing calcium twice disclosed by the invention not only has the advantages of the malt sugar complexing calcium being low in cost and obvious in growth promotion effects, but also has the advantages of the amino acid complexing inorganic calcium being high in biological value, stable in chemical properties and good in palatability.

Description

technical field [0001] The invention relates to a complex, in particular to a secondary complex calcium complex, a preparation method and its use in animal feed additives. Background technique [0002] Calcium is the first mineral element in the animal body, and calcium accounts for 1-2% of the animal's body weight. 99% of calcium is found in bones and teeth, and the rest is found in soft tissue fluids. Obviously, calcium plays an important role in the development and maintenance of bones and teeth, in addition, calcium has many important biological functions. At present, in livestock production, inorganic calcium such as lime powder, calcium carbonate and calcium hydrogen phosphate are the main calcium sources. Among them, calcium carbonate is the most widely used due to its high calcium content, safety, effectiveness, and especially the advantages of low price. . Although calcium carbonate has high content and low price, due to its extremely low solubility, calcium carb...
