摘要
早期断奶技术可通过提高母猪年生产力、饲料利用率等方式降低饲养成本,进而提高生猪养殖经济效益,对生猪养殖具有重大意义。但早期断奶技术也造成了仔猪断奶应激、腹泻率增加等问题,从而提高仔猪发病率和死亡率。文章综述早期断奶仔猪存在的主要问题,从仔猪饲养管理、生理调控和营养调控方面讨论仔猪早期断奶应激的应对策略,为缓解仔猪早期断奶应激综合征提供参考,为仔猪早期断奶技术在畜牧生产中的进一步应用提供参考。
Early weaning technology can reduce the feeding cost by improving annual productivity of sows and feed utilization rate, and thus improve economic benefits of pig breeding, which is of great significance for pig breeding.However, early weaning technology also causes problems such as weaning stress and increased diarrhea rate, thus increases the morbidity and mortality of piglets. The paper reviews the main problems existing in early weaning piglets,discusses the coping strategies of early weaning stress in terms of feeding management, physiological regulation and nutritional regulation of piglets, to provide reference for relieving early weaning stress syndrome and further application of early weaning technology in animal husbandry production.
