The invention relates to the field of laying hen breeding, in particular to a compound feed additive for improving egg shell strength of laying hens and a preparation method of the compound feed additive. The method has the beneficial effects that the eggshell strength is the core problem of the egg breaking rate in the later egg laying period of the laying hens, and the main reason of the egg breaking rate in the later egg laying period and the main mechanism of improving the eggshell strength are clearly researched; the industrial problems are solved by comprehensive methods such as improvement of overall immunity, intestinal health, liver health, fallopian tube health, calcium and phosphorus absorption promotion, trace element supplement, direct solution of eggshell strength improvement factors and the like. 本发明涉及蛋鸡养殖领域，具体为一种改善蛋鸡蛋壳强度的复合饲料添加剂及其制备方法。本发明的有益效果：蛋壳强度是蛋鸡产蛋后期破蛋率的核心问题，本发明研究清晰了产蛋后期破蛋率的主要原因，以及改善蛋壳强度的主要机理，通过提高整体免疫力、肠道健康、肝脏健康、输卵管健康、钙磷促进吸收、微量元素补充、蛋壳强度改善因素的直接解决等综合性方法解决行业难题。
