Sperm quality of split semen samples (n = 12 boars) assigned to four groups: (1) BTS extender with antibiotics, storage at 17 °C (17 °C, BTS), (2) BTS extender with antibiotics (AB), storage at 5 °C (5 °C, BTS), (3) AndroStar Premium with AB, storage at 17 C° (17 °C, APrem), (4) APrem without AB, storage at 5 C° (5 °C, APrem). (A) Total motile spermatozoa (%; means ± SEM) after 24, 72, and 144 h of storage. (B) Plasma membrane and acrosome intact (PI-negative and FITC-PNA negative) spermatozoa (%; means ± SEM) after 72 h of storage. (C) DNA fragmentation index (DFI %; means ± SEM) after 72 h of storage. *Values of 5 °C, BTS differ from all other semen groups at a given storage time (p < 0.05).
