Premixing feed containing organic trace elements, for chicken and preparation method of premixing feed

Abstract

The invention relates to a premix feed containing organic trace elements, for chicken and a preparation method of the premixing feed. The premix feed comprises the following raw material components ofan iron glycine complex (chelated) compound, an iron amino acid complex, a zinc methionine hydroxy analog complex (chelated) compound, a manganese methionine complex (chelated) compound, a cobalt acetate premixing agent and a carrier. The invention further relates to the preparation method of the premix feed containing the organic trace elements for chicken. The preparation method comprises the following steps of adding the obtained feed to a complete formula feed for laying hens and breeding hens according to a ratio being 1-2kg / ton for using. When the premix feed is used for the laying hens, the laying rate is high, the egg weight is high, the egg-to-feed rate is high, the strength of eggshells is high, and broken egg yield is low; and when the premix feed is used for the breeding hens, the breeding performance is high, the breeding egg fertilization rate of breeding eggs is high, the qualified rate of the breeding eggs is high, and the hatching rate is high. The premix feed disclosed by the invention has the characteristics of being high in digestivity, high in biological value, and sufficiently meets the characteristic of nutrient requirements of trace elements to the layinghens and the breeding hens, and is environmentally-friendly, so that environmental pollution pressure is reduced. The preparation method disclosed by the invention is high in mixing uniformity and simple in technology, and can effectively control the feed cost.

Description

technical field [0001] The invention relates to the field of premixed feed, in particular to an organic trace element premixed feed for chickens and a preparation method thereof. Background technique [0002] Trace elements, as components or cofactors of enzymes, participate in the metabolism of the three major nutrients (proteins, sugars and lipids) in animals, and affect the reproductive function and production performance of animals. Zinc, manganese, iron, and cobalt are trace elements necessary to ensure the healthy growth and efficient production of laying hens and breeders. Zinc deficiency can lead to malformation of breeder embryos, hypoplasia of thighs, and easy death; dysplasia of oviducts and ovaries in laying hens, decreased egg production and eggshell quality, and low hatchability. Zinc deficiency leads to weakened hormone activity and decreased immunity. Studies have shown that zinc is a cofactor for more than 200 enzymes, induces metallothionein formation, is...

AI Technical Summary

Problems solved by technology

[0003] At present, there are too many inorganic trace elements in the chicken feed on the market, which is harmful to the growth and development of chickens and environmental protection.

Especially in the existing actual production, in order to ensure a sufficient nutritional level, the use of high doses of inorganic trace elements has resulted in an increase in the residual amount of some trace elements in the body, affecting the taste of food and even threatening human health.

And most of the trace elements are excreted into the environment, increasing the environmental burden
