Preparation method of tryptophan chelated copper for feed

Abstract

The invention discloses a preparation method of tryptophan chelated copper for feed and belongs to the field of feed additives. The raw materials for producing the tryptophan chelated copper comprisetryptophan, copper sulfate and a 10% sodium hydroxide aqueous solution; through preparation of the aqueous solution, a chelation reaction of the tryptophan and the copper sulfate, separation and drying and other processes, the tryptophan chelated manganese is prepared. The technology has the advantages that industrial production of the tryptophan chelated copper is achieved, the technology is simple, and the production cost is low; the feed prepared through the tryptophan chelated copper is good in palatability and high in absorptivity; through the tryptophan, the functions of promoting ingestion, weakening a stress reaction, improving animal sleep, increasing the antibody of animal fetuses and offspring, improving the lactation of dairy animals, lowering the application amount of good-quality protein in daily ration, reducing the feed cost and the like on animals are achieved; the microelement copper is of vital importance to the animals, when the copper is sufficient, the animals generally have anemia, poor bone growth, slow growth and dysgenesis of newly-born young animals, clothing hair decolorization or abnormal growth, heart failure, stomach and intestine function disorder and the like, and after the copper is chelated with the tryptophan, the absorptivity is greatly increased.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a preparation method of tryptophan chelated copper for feed. Background technique [0002] Trace elements are one of the essential nutrients in the growth process of animals. Initially, trace elements were directly added to the feed in the form of inorganic salts, such as ferrous sulfate and copper sulfate. In the digestive tract, it is easy to form corresponding salts with low solubility with the common phytic acid anions and oxalate anions in the feed through biochemical reactions in animals, which are not easily absorbed by the intestinal tract. With the development of the feed industry, trace element additives such as amino acid and trace element chelates have been gradually developed. It is characterized by stability, high efficiency, and low toxicity. It is easy to digest and absorb in the intestinal tract, which is beneficial to animal growth and can prevent and control trace...
