Sperm motility of boars (n = 34) in an AI centre (experiment 2). Split semen samples were preserved in AndroStar® Premium extender and stored at 17 °C with antibiotics or at 5 °C without antibiotics. a Total motile spermatozoa (%; means ± SEM). *Values differ between storage temperature groups at a given time point (P < 0.05). b Boars (n) with sperm motility less than 65% in both semen groups
