The objectives of this project were:
1. To determine the effect of weaningtime (i.e. hour of weaning) on the interval from weaning to estrus, timing of the luteinizing hormone (LH) surge, timing and number of ovulations and subsequent reproductive performance of sows kept under short or long photoperiod.
2. To determine the feasibility of fixed time artificial insemination (AI) following this treatment.
