Abstract

The meat production traits treated here may be subdivided into the categories of reproductive and production performance. For both the use and development of special sire lines, complementary population differences are important. Crossbred sires compared to purebreds have no influence on maternal productivity but have a favourable effect on conception rate. For the various production performance traits, special combination effects are most important. In the event of selection solely for production performance, special attention must be paid to stress resistance and meat quality traits. Given consistent selection of halothane negative animals within the dam line, halothane positive sire line boars may be used.
