Thirty-two boars (16 littermates) were reared from 3Â½ to 5Â½ months in either an all-male group or with fence-line exposure to cycling sows and gilts. Exposure to females did not significantly increase testicle or accessory gland weights, sperm production, or libido score. Boars that displayed more sexual activity (mounts and sheath sniffs) from 3Â½ to 5Â½ months of age performed superiorly in mating tests at 5Â½ and 7Â½ months of age. Libido scores of littermate boars were very similar.; Swine Day, Manhattan, KS, November 13, 1980
