Investigation of selected biochemical parameters of local chickens with different age and sex in Al-Ahsa, Saudi Arabia.

In many species of birds, normal values for hematological and biochemical factors were measured and data base was established as their blood-profiles. In local Saudi chicken, measurement of serum biochemical values, which are important for diagnosis of clinical signs and symptoms when affected by diseases, are limited. Therefore, this study was carried out to investigate serum's biochemical values of local Saudi chicken. Therefore, forty chicks (1 month old; 20 males and 20 females) and another forty chicks (3 month old; 20 males and 20 females) were obtained from the farm of the Veterinary Research Station, King Faisal University, Al-Ahsa, Saudi Arabia and used as materials in the study. Blood samples were collected from all birds and the harvested sera were kept frozen at -20 degrees C until the time of analysis. The present findings indicated no significant difference (p > 0.05) of all examined biochemical parameters between male and female chickens or young and old birds. Interestingly, all investigated biochemical parameters in these chickens were lower than the recorded reference values of other birds except for glucose which exhibited higher values than the reference. The reported lower serum cholesterol and triacylglcerol concentrations might be reflected on their concentrations in meat and protecting human beings from atherosclerosis. Therefore, estimation of lipid profile in these birds is recommended for future study.
