摘　　要：叙述了目前国内外的氧化锌包被技术,对包被氧化锌与高剂量普通氧化锌的作用效果进行对比,分析总结了目前已有的氧化锌包被技术优点、缺点。包被氧化锌可使氧化锌顺利通过仔猪的胃部到达肠道,在肠道中崩解被仔猪吸收,可以显著降低氧化锌的添加量。包被氧化锌还存在包被成本较高,质量不一,过胃效果不稳定等问题,有待进一步研究。This paper summarizes the current zinc oxide coating technology at home and abroad,compares the effect of coated zinc oxide with high-dose ordinary zinc oxide,analyzes and summarizes the advantages,disadvantages and future development trend of existing zinc oxide coating technology.Coated zinc oxide can make zinc oxide smoothly through the stomach of piglets to the intestinal tract,in the intestinal disintegration of piglets absorption,can significantly reduce the amount of zinc oxide.There are still some problems in coating zinc oxide,such as high cost,different quality and unstable gastric effect,which need further study.
