摘　　要：屠前停用日粮中矿物质添加剂不影响猪的生长性能、胴体品质,同时还可降低饲料成本,减少粪中矿物质元素的排泄量,降低对环境的污染,是一安全、环保、节本增效的饲养技术。主要综述了这一技术的研究结果,为该技术应用推广提供参考。Deleting the dietary mineral premix in late finishing pigs Would not affect growth performance, carcass traits and pork quality, at the same time it can decrease feed cost, fecal mineral content,environmental pollution. Omitting the dietary mineral premix before slaughter was secure, uncontaminated, lower cost and high benefit breeding practice. The article reviewed the effect of removing mineral premix from the diet of pre-slaughter pigs on growth performance, carcass characteristics, mineral metabolism in tissues, and fecal mineral excretion in order to provick a basis for application and popularization.
