摘要

Abstract

Second litter syndrome(SLS)in sows is widespread worldwide.Sows with SLS have a lower litter size of the second parity than the first parity,the sows may have a lower estrus rate and a high culling rate,which waste the reproductive performance of low-parity sows,and the lifelong reproductive performance of sows with SLS is relatively reduced,while the breeding cost increases accordingly.In this paper,the causes and mechanisms of the formation of SLS are sys-tematically reviewed,and targeted prevention and treatment measures are also put forward,so as to provide theoretical basis and technical support for the stable development of sow reproductive performance,as well as the stable and healthy development of pig industry.Exploring the occur-rence mechanism of SLS in different pig farms supplies scientific research approach to deal with SLS,and to avoid the negative effect of SLS on reproductive performance in the subsequent parity.Precise feeding,nutritional regulation,and drugs research and development in reproductive regulation and their reasonable utilization will be the key points to solve the second litter syndrome.
