The results of acrosome intactness are shown in the
Table 3. After incubation at 17 ◦C for 1 to 3 h, the percentage
of intact acrosome in the AA-2G group was not significantly
different from that of the control. After incubating for 4 h, a
greater (P < 0.05) proportion of spermatozoa was identified
as having intact acrosomes (60.40%) in the AA-2G group
when compared with the control (46.0%).
The capacitation rates of boar spermatozoa treated with
or without AA-2G are presented in Table 4. A decrease
