摘　　要： 断奶日龄与断奶后仔猪生长发育和母猪生产性能发挥密切相关。该文回顾了国内外有关不同断奶日龄对仔猪生长发育、行为习性、消化生理与免疫机能以及母猪繁殖性能等方面的研究进展,分析了早期断奶技术在规模化养猪生产中,对改善母猪生产能力和设备利用率,降低饲料消耗,提高养猪生产效益所起的作用,断奶应激可能对仔猪生产的不良影响,以及目前有关技术研究与应用中存在的主要问题,探讨了我国在规模化养猪生产中应用早期断奶技术需解决的问题及今后的研究方向。 The weaning ages are closely related to the growth of piglets and performance of sows.The paper re- viewed the effects of different weaning ages on the growth,behavior,digestive physiology and immune function of piglets and the reproductive performance of the sows from the national and international research work.Effects of early—weaned technology on improving the sow performance and equipment efficiency,reducing feed consump- tion and increasing the benefit of pig production were analyzed.And besides,possible negative effects of early—weaned stress on the production of piglets,and the main problems in related research and technological applica- tion were also stated.Finally,some problems which need to be resolved for applying the early—weaned technolo- gy in intensive pig production and future research topics were discussed.
