LEROY – About $70,000 worth of bull semen was stolen from a barn in rural LeRoy yesterday, according to  the farm’s owner. “They took the whole storage canister,” said the farmer, while rolling up his sleeves and entering the barn. “It took me over a year to save up all that semen.”  The vials of bull semen were taken from his unlocked milking parlor sometime between April 1 and  7. “It’s gonna be a long week,” the farmer added as he applied lubrication to his latex gloves and approached the bullpen. “But those bulls don’t milk themselves.” Ị
