Abstract: The present study was conducted to examine urinary and plasma purine derivatives in light to different feeding protocol; to assess tissue xanthine oxidase activity in plasma, liver and intestine in relation to breed. Breed-related differences in tissue xanthine were observed. Arabi camels have higher figures compared to Anafi. Xanthine oxidase activities in Arabi plasma, liver and intestine were 0.9±0.1, 0.18±0.09 and 0.10±0.03, whereas in Anafi were 0.4±0.09 unit/L, 0.06±0.01 unit/gram wet tissue, 0.09±0.02 unit/gram wet tissue, respectively. Total urinary purine derivatives as a function of feed intake (11.43 vs. 15.09 mmol/d). Allantoin and uric acid compared 75.6 and 15.4% of total purine derivatives, in both fed and fasted camels, but hypoxanthine plus xanthine was 9%.
