Abstract

Acanthopanax senticosus, a member of the Araliaceae used as an invigorant in traditional Korean medicine, is known to relieve physical fatigue. The principal objective of this study was to evaluate the effects of eggs laid by hens fed on Acanthopanax senticosus extracts on physical endurance and reproductive parameters. Male Sprague-Dawley rats at 4 wk of age were divided into 3 groups of 15 rats each: group A (14% egg yolk powder from hens fed with Acanthopanax senticosus extracts+86% AIN-93G), group B (14% plain egg yolk powder + 86% AIN-93G) and group C (7% fat source + 93% AIN-93G), and studied for 5 wk. The rats' physical endurance was measured via forced swimming tests. According to the results, 53.3% rats of group A swam for longer than 20 min, in group B and C, only 48.9% and 46.7% of the rats achieved this. In terms of reproductive parameters, sperm motility was significantly higher in group A than in groups B and C (p<0.05). However, no differences in sperm count were detected among the groups. Additionally, the serum testosterone levels of groups A and B were higher than that of group C. Our findings suggest that rats fed with egg yolk powder from hens fed on Acanthopanax senticosus extracts may improve athletic endurance and reproductive parameters in rats.
