Direct Ovarian Observation in the Pig by Means of Laparoscopy

Summary. The development of a laparoscopy technique in the gilt which allows repeated direct observation of ovarian cyclicity with minimal surgical stress and trauma is described. Follicular activity before, during and after ovulation can be observed as well as corpus luteum development, especially during critical periods, such as oestrus. This technique may have application in studies of early embryonic growth and as a tool for investigating the cause of early embryonic death.
