摘要/Abstract

摘要：

母猪二胎综合征在全球范围内普遍存在，具有二胎综合征的母猪二胎产仔数低，通常也表现出发情率低、淘汰率高，浪费了低胎次母猪的繁殖性能，且二胎综合征母猪终身繁殖成绩相对降低，养殖成本相应增加。本文综述了二胎综合征形成的原因、发生机制，并有针对性地提出了防治措施，为母猪繁殖性能稳定发挥、养猪业平稳健康发展提供理论依据和技术支撑；也为深入探究不同猪场二胎综合征的发生机理提供科学思路，以期避免二胎综合征对后续胎次繁殖性能的影响。精准饲喂、营养调控以及繁殖调控药物的研发与科学使用，将是解决二胎综合征的重点。

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 systematically 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 occurrence 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.

Key words: second litter syndrome, sow, effect, mechanism
