Blood oxidative status, hemoglobin and pre-weaning vitality in calves.

摘要

Oxidant/antioxidant status. hemoglobin and vitality was evaluated in 253 two to three month old pre-weaning buffalo calves. 39% of the examined calves showed pre-weaning inferior vitality with lethargy, reduced growth, rough coat and signs of scaring.These calves had high blood malondialdehyde (MDA, P<0.001) and nitric oxide (NO, P<0.001), but low catalase (CAT, P<0.001), superoxide dismutase (SOD, P<0.001), ascorbic acid (P<0.01), glutathione (GSH,P<0.001), total antioxidant capacity (TAC, P<0.001), zinc (Zn, P<0.01), copper (Cu, P<0.01), iron (Fe, P<0.05) and selenium (Se, P<0.001). Electrical conductivity and derivatives of hemoglobin did not vary. We find high correlation between oxidant/antioxidant status of buffalo-calves and pre-weaning vitality.
