光照对后备母猪生长和繁殖性能的影响研究进展

Effects of Light Exposure on Growth and Reproductive Performance of Replacement Gilts:A Review

光照在后备母猪养殖中发挥着关键作用,许多研究表明科学合理的光照管理可显著提前后备母猪的初情日龄,促进发情,从而提高养殖经济效益。但是目前在我国养猪生产中对光照管理仍然不够重视,大多依赖从业者的实际生产经验,缺乏具有权威性的光照参考标准。本文综述了光照强度、光照时间、光的波长以及不同光源对后备母猪生长和繁殖性能的影响,以期为后备母猪生产中合理利用光照提供理论参考。

Light plays a crucial role in the breeding of replacement gilts,and numerous studies from both domestic and international sources have demonstrated that scientifically sound light management can significantly improve the age at puberty and estrus of replacement gilts,thereby enhancing the economic efficiency of breeding.However,in China,there remains insufficient emphasis on light management in pig farming,with many practitioners relying on empirical knowledge rather than authoritative and convincing light standards.This article provides a comprehensive overview of the impact of light intensity,lightduration,light wavelength,and different light sources on the growth and reproductive performance of replacement gilts,aiming to offer theoretical references for the rational use of lighting in replacement gilt production.
