后备母猪“五阶段”营养与“限速不限饲”饲喂模式探索

Exploration of Gilts′Five-Phase Nutrition System and Feeding Mode of Growth Control without Restricted Feeding

在养猪生产中,随着繁殖场的规模化、标准化发展,想要保证繁殖场稳定、高效、高产,后备母猪的质量成为稳定繁殖场正常生产的保障。后备母猪的质量除了受品种品系、育种选留选育、猪场生产管理等因素的影响外,还受营养及饲喂管理的影响。文章主要对后备母猪的饲喂模式研究现状及营养需要进行综述,并阐述“五阶段”培育的营养标准以及“限速不限饲”的饲喂模式,以期为畜牧工作者提供参考。

In pig production,with the development of scale and standardization of pig breeding farms,the quality of gilts has become the guarantee for stabilizing the normal production of the breeding farms to ensure the stability,efficiency,and high reproductive performance of the farms.The quality of gilts is not only affected by pig breeds and strains,breeding and selection,and production management of the farms,but also by nutrition levels and feeding management.In this paper,in order to provide references for the industry,the research progress of nutritional requirements and feeding patterns of gilts were reviewed,meanwhile,the nutritional standards of five-phase feeding and the growth control without resteicted feeding were expounded.
