ABSTRACT
Mohebbi-Fani M, Mirzaei A, Nazifi S, Tabandeh M.,
Superoxide dismutase, glutathione peroxidase and thiobarbituric acid in erythrocytes of ewes during breeding
and pregnancy, Onl J Vet Res., 25 (12):889-901, 2021. We report anti-oxidant status in erythyrocytes of 3 to 5 year old 105 fat-tailed ewes during
breeding and early-to-mid pregnancy under drought conditions. We measured erythrocyte
superoxide dismutase (SOD), glutathione peroxidase (GPX) and thiobarbituric reactive substances (TBARS) at days 1, 7, 21
and 120 starting with introduction of rams. Ewes with ≥2.5 ng/ml progesterone
at day 120 were considered pregnant (91%). By day 21 we found that plasma SOD
declined -49% and GPX -81% (P < 0.05) but TBARS increased 71% (P < 0.05) maintaining
trends to day 120. These results suggest that increased oxidation within reproductive
tissues with protein deficiency may have reduced plasma SOD and GTX and boosted
TBARS.
