Intensive sheep production systems seem to be an appropriate means of fully using the available resources, particularly the forages, of the southern region. In such systems, ewes should lamb first at approximately 1 yr of age. Programs to accomplish this goal must be well-planned and carefully integrated and executed. The primary goal is to achieve two-thirds of the ewe's projected mature weight before exposure for breeding. General management must reduce heat stress and parasitism. Forage quality must be maintained at a level consistent with National Research Council requirements for energy and protein. Protein is not normally a limiting factor. Energy supplementation and grazing pressure can be used to maintain growth without over-condition, which reduces subsequent performance.
