Figure 7.
Prevalence of non-viable sperm with normal tail morphology or with proximal or distal CD or bent tail during storage at 17 °C up to 168 h and subsequent thermic incubation at 38 °C for 3 h. Extended semen originated from samples with either enhanced (≥ 15% = high MAS; n = 15 boars) or low (< 5% = low MAS; n = 11 boars) prevalence of cytoplasmic droplets and/or bent tails. An asterisk (*) indicates a significant difference between sperm with a CD or bent tail and normal sperm within a time point (p < 0.05). There were no differences between normal sperm from high and low MAS samples (p > 0.05).
