Figure 1: Changes in (a) total motility and (b) progressive motility of boar lipid stored sperm with dietary Vitamin E during 120-h storage at different experimental week (0, 8, 12 and 16 w). Data are presented as means ± s.d. (n = 10 replicates/vitamin group, one ejaculate per replicate). *P < 0.05, compared with Vitamin E diet (200 mg kg−1). #P < 0.05, compared with week 0 (within the same storage time).
