摘  要:
后备母猪种质的好坏直接影响着规模化猪场的非生产天数的多少,其中能量、蛋白质和维生素对后备母猪初情期启动机制影响很大,因此可通过精准营养供给模式合理调控后备母猪初情期启动过程.本文对影响后备母猪初情期启动的因素以及分子营养对初情期启动机制的调控进行综述,旨在为规模化猪场后备母猪营养调控提供技术参考.

摘  要:
The quality of sow germplasm directly affects the number of non-production days in large-scale pig farms. Among them,energy,protein and vitamins had a great influence on the start-up mechanism of gilts during the initial period. The start-up process of gilts was regulated reasonably by precise nutrient mode supply. This article reviewed the factors affecting the start-up of the gilts and the effects of molecular nutrition on the start-up mechanism of the gilts,aimed to provide reference for nutritional regulation of gilts in large-scale pig farms.
