In order to achieve more than one lamb crop per year, it is necessary to breed ewes during lactation or following a relatively short lactation. Many times this means conception must occur during the time when ewes are normally going into anestrus or are in anestrus. This preliminary study was conducted to evaluate breeding response of ewes subjected to controlled light following weaning at 45 to 60 days postpartum.
