Abstract :

Evaluation of blood parameters of the local hens of Saudi Arabia as subjected to seasonal variation was not documented well in the literature. This study was an attempt to determine the effects of natural seasonal changes of temperature on hematological components and chemical constituents of : the local hens of Saudi Arabia, Naked neck breed and a white leghorn layers. A total of 91 hens of two local of hens (naked neck and Saudi Local) plus an exotic white leghorn hens at 20 weeks of age were used in this study. These were divided into 29 hens of naked neck, 34 hens of Saudi local and 28 of white leghorn laying hens. The results of the study indicated a significant interaction between breed X period only on blood triglycerides. Effect of the breed was evident on mean corpuscular hemoglobin, blood urea nitrogen, total bilirubin and phosphorus. Seasonal variations in temperature had a significant effect on RBC, PCV, WBC, glucose, blood urea nitrogen, total bilirubin, creatinine, calcium, phosphorus, sodium and potassium. It was concluded that breed of the bird had no significant effect on the blood constituents of the birds, however, seasonal effect was evident on most of these constituents.
