Adequate trace elements are necessary for optimum production in sheep. The environment (nutrition, management, weather, etc.) is heavily responsible for lambing and/or weaning success. Second only in importance to mating weight and mating condition, the trace element status of ewes at mating is the nutrition factor with the greatest influence on the number of lambs that will be born.
