Allicin (AL) is one of the biologically active substance in garlic. Many researchers found that AL exhibits strong antioxidant activity and considered to represent anti-aging effect in vitro. The objective of this study was to investigate the effects of allicin treatment during porcine oocyte aging and their in vitro development. The oocyte was maturated in vitro for 44 h (control) without AL or 44+24 h IVM (24 h aging) with 0, 0.1, 1, 10 and 100 μM allicin (0 AL, 0.1 AL, 1 AL, 10 AL and 100 AL). The 1 AL treated group was significantly increased on maturation rate compared to the 0 AL treated groups, but the other treated groups were not different compared to the 0 AL treated group (p < 0.05). The 1 AL treated group was significantly increased on normal spindle formation and chromosome alignment compared to 0 AL treated group. We checked the effect of AL on parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) embryo development using aged oocytes. PA embryos in 1 AL treated group significantly increased the cleavage and blastocyst formation rate compared to control (p < 0.05). However, SCNT embryos of 1 AL treated group were no significant differences in embryo development. In PA embryo quality, the total cell number was significantly higher in 0.1 AL, 1 AL and 10 AL treated groups than control and DNA fragmentation rate in 1 AL was the lowest among all groups. SCNT embryo in 1 AL significantly increased total cell number and decreased DNA fragmentation. The AL treatment on aged oocyte enhanced PA and SCNT embryo developmental capacity. Therefore, AL may be helpful for assisted reproductive technology applying aged oocytes.
