Performance records of 275 boars, beginning at 65 and ending at 250 lbs., were analyzed to determine correlations of performance traits. Fastest growing boars were more efficient (r=-.49). In addition, faster gaining boars also tended to have more backfat (r=.20). Backfat thickness and feed efficiency were not related (r=.0l). Average daily gain from 65 to 220 lbs. was highly correlated with average daily gain from 65 to 250 lbs. (r=.92), which suggests that boars need not be tested to heavier weights. The feed/gain ratios during both test periods likewise were highly correlated (r=.82).; Swine Day, Manhattan, KS, November 11, 1976
