Description:	The use of equine chorionic gonadotrophin (eCG) in oestrous induction protocols is associated with antibody production against eCG. Moreover,there are important equine welfare issues involved in its production and the development of viable protocols without eCG in dairy goats is essential.The aim of this study was to assess oestrus and ovulatory responses of short-term oestrous synchronization protocol with or without eCG innulliparous (NUL) and multiparous (MUL) dairy goats during the breeding season. In summary, in short-term protocols foroestrous synchronization in cyclic dairy goats, the addition of eCG led to a shorter interval from sponge removal to ovulation and increased number ofanimals that ovulated.
