Abstract: The study was designed to investigate the effect of age, breed, sex, and breeding season on thiamine and ascorbic acid status (AA) in camels (Camelus dromedarius). A total of 375 camels were sampled over a one-year field survey in Butana area, Central Sudan. No effect of sex on thiamine and ascorbic acid levels was observed. The breeding male and female camels showed higher status of plasma thiamine and lower ascorbic acid as compared to non-breeding camels. Thiamine plasma contents showed variation with respect to age. The thiamine plasma levels for neonate, yearling, and adult were 59.9±4.4, 70.5±8.9 and 88.9±6.7 μg/L, respectively. The corresponding figures for AA were 6.2±1.0, 4.9±0.9, and 4.5±0.8 mg/L, respectively. The Arabi showed higher ascorbic acid (5.9±1.0) than Anafi (4.2±0.9 mg/L). However, no significant breed variation for thiamine status was indicated.
