Abstract
Prior work at SDSU (see previous report SHEEP 95-1) has shown the success of fall lambing performance from mature crossbred ewes. In most cases, ewes in the previous studies were spring-born ewes that had been shifted to the fall system. Thus, direct selection of progeny for fall lambing potential was not possible. More rapid progress should be made if replacements are selected from fall lambing ewes. This study was initiated to evaluate the effectiveness of selection for fall lambing under farm and range flock management systems
