| Abstract: | Duroc was selected and bred using the method of combination with close and open breeding and composed base population . Daily gain and lean meat percentage of the base population were major selective traits by the results of productive performance testing . After five years selecting , male daily gain was 856 g , famale daily gain was 833 g and increased 6.87% , 5.98 % respectively ; male lean meat percentage reached 66.2% , famale lean meat percentage reached 65.6% and progressed 2.32 % , 2.66 % respectively ; the swine's backfat thickness reduced 0.8 mm , 0.6 mm respectively . |
