Effect of different seasons on oxidative stress parameters in barberi and pashmina goats

The present study was undertaken to observe effect of different season on oxidative stress parameters in tropical and temperate region goats. 12 adult goats of each breed viz. Pashmina and Barberi, belonging from temperate and tropical region were selected for study. Blood sample were collected during peak winter, moderate season and peak summer from both breeds. Oxidative stress parametes were analyzed. The mean values of oxidative stress parameters viz. lipid peroxides (LPO), reactive oxygen species (ROS), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) in Barberi goats were found significantly higher during peak summer as compared to peak winter and moderately cold season where as the levels of these parameters in Pashmina goats were found significantly higher during peak winter as compared to summer and moderate season. Findings of this study indicated that both peak winter and peak summer are stressful to both Pashmina and Barberi goats however peak winter is more stressful in Pashmina and peak summer is more stressful in Barbei goats as compared to other seasons.
