黏土的作用机理及其在畜禽生产中的应用研究进展

A new review on mechanism and application in livestock and poultry production of clay

黏土是一类含有碱金属和碱土金属阳离子以及少量其他元素组成的结晶水合铝硅酸盐复合物,具有粒径小、表面积大、吸附性强和离子交换等特性,可改善畜禽生长性能,促进畜禽机体健康。文章就黏土的种类、作用机理及其在畜禽生产中的应用进展进行综述,为其科学推广应用提供理论依据。

Clays are crystalline,hydrated aluminosilicate molecules composed of alkali and alkaline earth cations along with small amounts of various other elements.Clay has specific physical-chemical properties such as high cation exchange capacity and standout adhesive ability due to its small particle size,large specific surface area and specific structures of porous layers,which could improve growth performance and intestinal health of livestock and poultry.This review focuses on the types of clay, mechanism of action and application prospects in livestock and poultry production,which may provide a theoretical basis for its scientific application.
