Influence of age on some serum constituents in racing Arabian camels, (Camelus dromedarius L)

Normal serum values were estimated for 15 clinically important biochemical variables and enzymes in the sera of healthy male and female adult racing Arabian camels, (Camelus dromedarius L.) and also in the sera of healthy male and female young Arabian camels, raised as potential racing camels. The results have indicated no significant differences in all analyses between male and female young Arabian camels. Similar results were also obtained from the corresponding adult camels except for small (12-17%), but statistically significant, variations in the activities of ALT, AST, CK and ALP, being higher in females than in males in the case of the three former enzymes, and the opposite for ALP activity. Moreover, age had a significant effect on some serum enzyme activities. ALT, AST, CK, LD and ALP activities were higher in young male and female camels compared to those of adults of the corresponding gender. However, the opposite was found with GGT.
