Abstract
A study was undertaken to compare the effectiveness of three different selection strategies in increasing weaning weight of a Dorper flock u nder natural conditions. Data were analysed by mixed model procedures. Direct selection for weaning weight under natural conditions proved t o be effective. Selection on breed standards and selection on weaning weight under natural conditions combined with feedlot performance were not successful in increasing weaning weight. Only direct selection fo r weaning weight under natural conditions is therefore recommended.
