The invention belongs to the technical field of feed additives, in particular to a composition of ester-type catechin and vitamin C palmitate for breeding pigeons and a preparation method thereof. The composition includes: EGCG-containing catechin crude extract, vitamin C palmitate, composite self-emulsifier, solidified dispersing powder, and filling auxiliary materials; in the preparation of the composition of the present invention, vitamin C palmitate and vitamin C palmitate are used. The encapsulation effect formed by the composite self-emulsifier can effectively ensure the stability and absorption of catechins, and also has a high-efficiency synergistic effect, significantly improving the bioavailability of ECGC, overcoming the conventional catechin instability problem, significantly Improve its biological efficacy, and use less amount, so it has better biological safety; the raw materials used in this composition are all food-grade or feed-grade raw materials, without the addition of any other chemical preparations, and can be used as a replacement antibody The functional additives are used to improve the antioxidant capacity and immunity of breeding pigeons and improve egg quality. |
