Data from Targhee, Suffolk x Targhee and Finnsheep x Targhee ewes which had completed a lifetime production study were used to determine the effect of lambing at 12 to 14 months on cumulative production. Ewes that lambed at 1 year of age gave birth to and weaned more lambs as well as gave birth to and weaned more pounds of lamb on a cumulative basis than ewes that failed to lamb at 1 year of age. Wool production was similar for the two groups of ewes. Ewes that produced a lamb at 1 year of age were more productive than those ewes that failed to lamb, even if the first year's production was not included.
