Effect of oral antioxidant supplementation on blood antioxidant status in trained thoroughbred horses.
Brief content of the article
The oxidant/antioxidant equilibrium of 40 trained thoroughbred horses was assessed during a period of three months under field conditions. Various markers for blood antioxidant status were measured: plasma ascorbic acid (AA), plasma anioxidant capacity of water soluble components, red blood cell superoxide dismutase, glutathione-peroxidase activity, plasma selenium, copper and zinc. The results of the field study indicated that trained thoroughbred horses undergo significant changes of several blood antioxidant markers and that oral antioxidant supplementation might partially counterbalance these changes by improving the hydrophilic, lipophilic and enzymatic antioxidant blood capacity.
