Investigation of Selected Biochemical Parameters of Local Chickens with Different Age and Sex in Al-ahsa, Saudi Arabia

Abstract

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.

Sex-related differences in hemato-biochemical indices of adult Vanaraja chickens during summer and winter seasons

“…TLC was lower than the finding in the previous study in Nicobari fowls [12]. Higher level of TLC count in males than females is similar to earlier reports [2,10,14]. The higher level of TLC in males may be due to sex hormone effect [2] or inherent sex difference.…”

“…Male had significantly (p<0.05) higher blood glucose levelin both seasons than females. Contrary to this finding previous studies showed nonsignificant differences in glucose concentration between male and female [2,8,10]. This finding was opposite to finding in Aseel female chickens [7] where a higher level of glucose found in female chicken.…”

“…The percentage of sex-independent different leukocytes was also similar to the finding of Albokhadaim et al . [10]. Lymphocyte was a predominant TLC in both sexes.…”

“…Higher level of TEC, PCV, and Hb concentration was observed in males due to effect of androgen. Nonsignificant effect of age on mean corpuscular volume (MCV), mean corpuscular Hb (MCH), MCH concentration (MCHC), and differential leukocyte count was observed in local Saudi chicken [10]. Changes in MCHC and MCV between male and female were observed previously [11].…”

“…Sex-dependent variability was observed in blood hematological parameters such as PCV, TEC, total erythrocyte count (TLC), and different leukocytes cell counts in Indigenous chicken [2]. Contrary to this in local Saudi chicken, these parameters were found higher in male compared to female [10]. Most of the hematological parameters were higher in males than females [11].…”
