Simple Summary: There is ongoing research regarding the application and efficiency of short-term oestrus synchronisation (ES) treatments using controlled internal drug release (CIDR) in goats raised under subtropical environments, but information regarding the extent of application of these protocols in the tropical region is limited. Although short-term CIDR-based protocols have been more widely studied and applied in the subtropical region, they are still challenged by ethical, technical, and economic issues. Tropical and subtropical regions have moderately seasonal to aseasonal goat breeds, and so, efficient protocols involving a reduced hormonal supply can be developed for the management of reproduction. Therefore, this review provides a scope of the application of short-term CIDR-based protocols and co-treatments and suggests areas of improvement. 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.
