Stress and antioxidative status of Zovawk piglets at different intervals of weaning

Abstract

Stress and antioxidative status of weaned Zovawk piglets were analysed by estimating stress and antioxidative biomarkers. Cortisol, neutrophil to lymphocyte ratio (N:L), SOD, GPx, catalase and concentration of GSH, TBARS and FRAP were estimated in blood samples on 0, 7th and 14th day of weaning. sAA activity was estimated in saliva samples on 0, 3rd, 6th, 9th, 12th and 15th day of weaning. Weaning stress caused changes in antioxidative status. On 14th day of weaning, cortisol concentration increased significantly while SOD and TBARS decreased significantly. N:L decreased on 7th and 14th day of weaning. GSH showed a declining trend in response to weaning while the catalase and FRAP were not influenced by weaning. sAA decreased significantly on 3rd day of weaning that decreased further on 9th day of weaning
