Oestrus suppression techniques in competition mares

This presentation will describe how unwanted oestrus behaviour presents and how to determine that the unwanted behaviour is truly related to the reproductive tract of the mare or with the reproductive hormone balance as opposed to other body systems. The normal reproductive cycle of the mare will be described along with the features of the seasonal phases of reproductive activity. The techniques available to suppress oestrus will be described along with the mechanisms of action from the use of exogenous progestagens, prolonging the length of the mares owns luteal phase, through to suppressing the hypothalamic-pituitary axis through negative feedback of GnRH analogues or vaccinating against GnRH. The implications on the future reproductive performance of the mare will be discussed along with the implications of the techniques on the mare's eligibility to compete under various disciplines.
