Update on the management of anoestrus and transitional phase in horses

Abstract

Background: Practitioners are regularly presented with mares in anoestrus or the transitional phase of the reproductive cycle. The first aim for the practitioner is to determine what stage of the cycle the mare is likely in and then determine the likely timescale to spontaneous cyclic activity. If it is desirable for the mare to be bred sooner than this, management and/or pharmacological strategies can be implemented in an attempt to advance cyclic activity.Aim of the article: This article aims to update the practitioner with regard to the current and future methods of management and pharmacological therapies available to stimulate cyclic activity in the mare in anoestrus or transitional phase of the reproductive cycle.
