title: Relation between antioxidant status and postpartum anestrous condition in Murrah buffalo.
abstract: OBJECTIVE
  Objective of the present study was to investigate the relation between antioxidant status and postpartum anestrous (PPA) condition in Murrah buffalo.
  
  
  METHODS
  Jugular blood samples were collected from two different groups of Murrah buffaloes each group consisting of 20 animals. Group I was of PPA and Group II were of cyclic buffaloes. The animals selected were examined for confirmation for cyclic and acyclic condition (>120 days) after calving by routine transrectal ultrasonography. Heard record was also used for cross confirmation.
  
  
  RESULTS
  The analysis of antioxidants in plasma and hemolysates revealed that the levels of vitamin E, β-carotene and reduced glutathione in plasma and superoxide dismutase (SOD) in hemolysate were significantly higher in cyclic animals than PPA animals. The levels of vitamin C, SOD and glutathione peroxidase in plasma did not show any significant difference among the two groups studied. The low antioxidant level in affected animals may predispose them toward PPA condition.
  
  
  CONCLUSIONS
  Stress imposed by pregnancy and lactation affected the reproductive performance in PPA animals which might be inherently more susceptible to these stressors than those who were normal cyclic as all the animals were maintained under similar feeding and management practices.
