Induction of Lambing at Weekly Intervals

Lambing season is the time in the sheep production year which demands the largest input of labor. Due to problems associated with the birth process, it is also one of the most critical times. By controlling the time of parturition, producers are better able to schedule labor and facilities more effectively. Ewes induced to lamb on specified days allow for more uniform groups of lambs for management practices. Flumethasone, a glucocorticoid, will induce parturition in ewes when administered late in gestation. The objective of this study was to determine the optimum range of days for once per week treatment for practical application of a grouped lambing program
