The objective of this study was to determine the effects of dietary supplementation of whole garlic powder(WGP) on semen characteristics and blood antioxidant level in boars. For this study, nine Duroc boars of 12 months age were used. Semen and blood samples were collected for 13 weeks, once in each week. The boars were fed the basal diet(BD; control) or BD supplemented with 3% WGP. There were no significant differences in the semen volume and sperm concentration between control and WGP group on all collection weeks. However, total sperm number per ejaculate was higher in the WGP group than that in the control group on collection weeks 6, 7 and 8(P<0.05). Also, on collection weeks 5, 6, 7 and 8, mean of total ejaculated sperm numbers per boar were significantly higher in the WGP group compared to control group(P<0.05). On the other hand, ejaculation frequency per boar(boar’s libido) and total ejaculated sperm number per boar were significantly increased in the WGP group compared to the control group, respectively(P<0.05). Although there was no difference in polyphenol level in seminal plasma between two treatment groups, polyphenol level in blood serum was significantly higher in the WGP group on collection weeks 9, 12 and 13(P<0.05). These results indicate that dietary supplementation of 3% WGP improves boar libido and semen productivity such as ejaculation frequency per boar, total sperm number per ejaculate, mean of total ejaculated sperm number per head, and elevate the blood level of antioxidant(polyphenol) in boar serum.
