Extract

Selection in a commercial sire line is primarily based on improvement of broiler traits and those reproductive traits affected by the breeding male i.e. fertility, hatchability and chick quality. However some consideration in the selection programme must be given to die egg production and quality traits as the pure line must be maintained and parent sires produced. Dam lines are also selected for broiler and reproductive traits with more selection pressure being brought to bear on the egg related traits than in the sire lines. Consequently, the cross-bred progeny of these lines, which are sold as commercial breeding stock, exhibit a high performance in both egg production and meat deposition. As the primary basis of selection is to effect development of the pure-bred lines the assessment of the relationships between broiler and reproductive traits will facilitate in the advancement of the selection programme.
