Seasonal breeding in sheep limits productivity of the ewe and creates an oscillating supply of lamb. A continuous breeding season would provide a more constant supply of lambs, allowing producers, feeders and packers to use their facilities and labor more efficiently. Induction of a fertile estrus during the normal summer anestrous period in the ewe would extend the lambing season and aid in leveling out the lamb supply. Alteration of the light : dark ratio was studied as a method to induce fertile mating during the summer in Targhee (1981) and Finn x Targhee (1982) ewes.
