Contents: The relationship between seminal plasma infusion and ovulation time in GnRH‐treated gilts was investigated. Following oestrus synchronisation with Regumate (Roussel Uclaf) and PMSG (Pregmagon Dessau) 14 gilts were injected with 75 μg GnRH (Gonavet “Berlin‐Chemie”) 80 h after PMSG. Seven gilts received an additional intracervical infusion of 80 ml seminal plasma 16 h after GnRH. The laparoscopic observation of follicular development and ovulation started 24 h after GnRH injection in 6 to 1.5 h intervals up to the completion of ovulation. The mean interval between GnRH and completion of ovulation was 40.1 1.6 h in gilts treated with seminal plasma and 40.8 0.7 h in control gilts. There was no additional seminal plasma related effect on the advancement of ovulation compared to GnRH only.
