Table 2 Fertility data of sows (experiment 2)

Semen storage	17 °C w/AB	5 °C w/o AB	P-value
Sows, n	94	95
Pregnancy rate day 24, %	98.9	98.9	1.00
Farrowing rate, %	96.8	98.9	0.37
Total number of born piglets	15.3 ± 0.4	15.8 ± 0.3	0.51
Total number of live-born piglets	14.3 ± 0.4	14.6 ± 0.3	0.94

Data for total number of born and live-born piglets are shown as means ± SEM. Values do not differ (P > 0.05).
Sows (n = 189) were inseminated with semen pools extended split-sample in AndroStar® Premium and stored at 17 °C with antibiotics (17 °C w/AB; 0.25 g/L gentamicin sulphate) or at 5 °C without antibiotics (5 °C w/o AB).
