Terminal sire line evaluations were conducted at a test station by collecting piglets from different sire lines and evaluating their performance up to slaughter. A minimum number of boars per line is set to avoid evaluating specific boar performance, and the piglet feeding behaviour is traced as well using a continuous data collection system. Sire lines are kept anonymous in results, but lines and suppliers are listed for each trial. In trial 1, Line A was found to higher average daily gain, less feed intake, and lower feed conversion. Line B had higher dressing and lean yield percent, less backfat, more marbling, and less drip-loss than Line A. The purpose of the evaluations were to show how different lines could be chosen for different end goals, to collect benchmark data, and to allow development or refinement of measurements.
