This review aims to provide an insight into the application and efficiency of CIDR-based protocols for ES in goats raised under tropical and subtropical environments. In temperate regions, short-term CIDR treatments are replacing long-term treatments and sponges used in earlier decades. In addition, the use of co-treatments for the induction of ovulation is gradually changing from hormonal to non-hormonal methods, given the drive towards clean, green, and ethical techniques for reproductive management. Whereas the subtropical region registers ongoing research in the development of new ES protocols, there are few reports from the tropics, particularly Africa, one of the regions with the highest population of goats. Therefore, this calls for research to develop the most appropriate protocols for these regions, since the protocols currently used are largely hormonal based, as they were developed for goats at higher latitudes. Management and environmental factors determine the breeding pattern of goats at tropical latitudes rather than photoperiods, and they are the main causes of reproductive seasonality. The use of ES methods, particularly short-term CIDR-based protocols, along with artificial insemination, may have a significant impact on the productivity of goats in these regions when these factors are controlled.
本综述旨在深入探讨基于阴道海绵栓（CIDR）的同期发情（ES）方案在热带和亚热带环境下饲养的山羊中的应用及效果。在温带地区，短期CIDR处理正在取代过去几十年使用的长期处理和海绵栓。此外，鉴于生殖管理朝着清洁、绿色和符合伦理的技术发展，诱导排卵的联合处理方法正逐渐从激素法转变为非激素法。虽然亚热带地区在新的ES方案开发方面有持续的研究，但热带地区，尤其是山羊数量最多的地区之一非洲，相关报道较少。因此，鉴于目前使用的方案主要基于激素，是为高纬度地区的山羊开发的，这就需要开展研究来为这些地区制定最合适的方案。管理和环境因素决定了热带地区山羊的繁殖模式，而非光周期，它们是生殖季节性的主要原因。当这些因素得到控制时，使用ES方法，特别是基于短期CIDR的方案，再结合人工授精，可能会对这些地区山羊的生产力产生重大影响。
