Abstract
The aim of this study was to study the effects of adding melatonin at different concentrations on the quality
of cryopreserved boar semen. Semen samples (n = 6) were collected by hand-glove technique. Semen samples
were diluted with Modena? and divided into 6 groups. According to the concentrations of melatonin at 0
(control, group A), 0.1 (group B), 0.5 (group C), 1.0 (group D), 1.5 (group E) and 2.0 mM (group F) to the lactose-egg
yolk extenders used to freeze boar semen with traditional method. Progressive motility, viability and acrosome
integrity were evaluated both before and after cryopreservation. The results showed that here was no significant
difference in percentage of progressive motility among groups. However, a higher percentage of progressive
motility was found in group D (39.17%). A higher percentage of sperm viability and acrosome integrity were
found in group F (28.33%) and group F (34.50%), respectively. In conclusion, the present results suggest that
adding melatonin between 0.1 and 1 mM during freezing yield a superior post-thawed semen qualities than
freezing without melatonin.
