Controlled Parturition in the Ewe

The ability to control the time of parturition offers the sheep producer a valuable management tool to increase the efficiency of his operation. In small flocks controlled parturition could be used for the entire flock. In larger flocks controlled parturition could be used effectively as a clean-up tool by inducing parturition in all ewes lambing by 141 days after removal of rams from the breeding flock. Advantages which the producer might obtain from controlled lambing include more efficient utilization of available space and labor, less death loss due to increased supervision and more uniform lamb crops
