Abstract

The invention belongs to the technical field of feed additives, and particularly relates to a composition of ester type catechin and vitamin C palmitate for breeding pigeons and a preparation method of the composition. The composition is prepared from catechin crude extract containing EGCG, vitamin C palmitate, a composite self-emulsifying agent, curing dispersing powder and a filling auxiliary material. In the preparation of the composition, the stability and the absorbability of the catechin can be effectively ensured by utilizing an encapsulation effect formed by the vitamin C palmitate and the composite self-emulsifying agent, an efficient synergistic effect is further achieved, the bioavailability of ECGC is remarkably improved, the instability problem of conventional catechin is solved, the biological efficiency of the ECGC is remarkably improved, the usage amount is lower, and the composition is suitable for industrial production. Raw materials used in the composition are all food-grade or feed-grade raw materials, no other chemical preparations are added, and the composition can be used as an antibiotic-replacing functional additive for improving the oxidation resistance and immunity of the breeding pigeons and improving the egg quality.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a composition of ester-type catechin and vitamin C palmitate for pigeon breeding and a preparation method thereof. Background technique [0002] As a traditional delicacy material, pigeon has high nutritional value. It is not only a precious delicacy, but also a high-end nourishing product. It is known as "one pigeon wins nine chickens". With the development of my country's economy and the improvement of living standards, more and more attention has been paid to the "three highs" caused by traditional high-fat and high-cholesterol diets. Healthy, low-fat, and low-cholesterol diets are favored, coupled with diversified consumption, Thereby the pigeon industry has developed by leaps and bounds, and the food of various characteristic pigeons is put on the homes of ordinary people. However, with the expansion of the scale of the pigeon industry, the popularization of commercia...
