title: Follicular dynamics and ovulation time in gilts and post-weaning sows.
abstract: Ultrasonography was used to study follicular dynamics from the beginning of estrus to ovulation in pubertal gilts and post-weaning sows. Ultrasound turned out to be a useful tool to determine patterns of growth of preovulatory follicles, to predict ovulation time, and to design protocols for fixed time insemination.
