'Department of Obstetrics and Reproduction, 'Research Institute, University of Veterinary Science, Budapest, Hungary Contents Three studies were carried out to monitor or induce ovarian activity and sexual behaviour in maiden, barren and postpartum mares during the anovulatory season. In the first study maiden and barren mares were followed up by regular blood sampling. In 39% of anoestrus mares the anovulatory season was started after December 1. Mares that stopped cycling before December 1 had significantly longer anovulatory period (P<O.OOl) and resumed cyclic ovarian activity one month later (P lodays, between 22 and 64 days) in 10 mares (43.5%). In the third study 44 mares in spring transition were treated with Altrenogest for 10 days. In 8 treated mares a GnRHchallenge (40pg Buserelin iv.) was carried out before treatment. Despite the same inclusion criteria used for all mares, in case of 11 mares (25%) the treatment was not successful and the ovulation occurred more than 20 days after the end of treatment (between 29 and 70 days). The result of the GnRH-stimulation gave an explanation for this difference.Mares that were treated successfully with Altrenogest had a higher maximum LH-response and area under the curve indicating higher LH-content of the
