The primary aim of this study is to assess the antioxidant status of newly born Aardi kids. Eighteen newly born Aardi kids were used in this study;sampled weekly as from week 1 to 4 for the assay of the plasma Total Antioxidant Capacity (TAC), ThioBarbituric Reactive Substances (TBARS), and Superoxide Dismutase (SOD) activities. For new-born, total blood antioxidants concentrations did not change during the four weeks of life. However, TBARS increased during the 2nd and 3rd week of age (p < 0.05). The results indicated that TAC in kids from birth to 4 weeks of age tended to increase, but not significantly. Serum TBARS concentrations increased on the 2nd week and decreased significantly on the 4th week of age. Serum SOD levels did not change significantly, even though, the trend showed a decline during 1st to 3rd week of age. The small decrease in serum TBARS in the serum of kids can be considered as an indication of decreased oxidants, which in turn, resulted in a reduction in serum SOD concentration. In conclusion, this basic data could help in understanding the adaptational physiology of young local Saudi goats.展开更多
