Breeding performance test results were obtained from large white boars which age ranged between 10 to 24 weeks. Average daily gain, feed conversion ratio, average back fat thickness, adjusted back fat thickness and selection index were 747.54 g./days, 2.36, 0.80 inches, 0.79 inches and 56.08 respectively. The statistical correlations between average daily gain and feed conversion ratio, average back fat thickness, adjusted back fat thickness were -0.70 (P < 0.01), 0.30 and 0.13, and also between feed conversion ratio and average back fat thickness, adjusted back fat thickness were -0.36 (P < 0.05) and -0.26, respectively. The boars were trained to mount a dummy for semen collection at about 170 days of age. Correlations between average daily gain, selection index and total motile sperm in semen were 0.37 (P < 0.05) and 0.21, respectively. The correlations between average daily gain, selection index and total motile normal sperm in semen were 0.34 and 0.22 respectively. The correlations between average daily gain and libido score, copulating ability score and leg conformation score were -0.08, -0.35 and -0.37 (P < 0.05) respectively. The correlations between selection index and libido score, copulation ability score and leg conformation score were -0.04, -0.31 and -0.33 respectively. The correlation between libido score and copulating ability score was 0.40 (P < 0.05). The correlations between libido score, copulation ability score and total motile normal sperm in semen were -0.06 and 0.03 respectively.
