The susceptibility of erythrocyte lipid to in vitro peroxidation as measured by TBARS (thiobarbituric acid-reactive substances) and concentration of reduced glutathione (GSH) in whole blood and erythrocyte suspension before and after incubation with hydrogen peroxide was assessed in ducks, chickens and pigs. A high susceptibility of erythrocytes to peroxidation in vitro was observed in all animals tested, but this susceptibility was of different intensity. Pig erythrocytes exhibited the lowest resistance to oxidative stress in vitro as compared with that in ducks (P < 0.01) and chickens (P < 0.02). A high level of GSH in the erythrocytes of ducks and chickens offers higher resistance to oxidative stress in comparison with that in the pig erythrocytes.
