Hematological and some biochemical values of indigenous chickens in Al-Ahsa, Saudi Arabia during summer season.

摘要

The uses of hematological and biochemical parameters in disease diagnosis are well documented. However, sex, age and nutrition are the major factors affecting avian hematology. The measurement of these parameters in relation to age and sexes in local Saudi chickens are limited. Therefore, a total of 80 local Saudi chickens of different age and sexes in summer season were divided into 4 groups. First and second groups constitute male chicks of one and three months old (n=20 for each). Chicks of the third and fourth groups were females of one and three months old (n=20 for each). The collected blood and separated plasma were used for determination of hematological and some biochemical parameters, respectively. Total Erythrocyte Counts (TEC), Total Leucocytes Counts (TLC) and Packed Cell Volume (PCV) were significantly (p<=0.05) higher in male than female chicks and were not age dependant. Hemoglobin and blood indices were not significantly (p>0.05) differed in all birds. They were ranged as 9.5-11.7 g dL-1, 97-108 m3, 30.7-34.1 pg and 28.6-34.3%, respectively. The percentage of heterophil, lymphocyte, monocyte, eosinophil and basophile were age and sex independent in addition, their values are ranged as 41.8-46.2, 43.2-48.8, 3.9-4.9 and 3.1-4.4%, respectively. The examined biochemical parameters were comparable in all birds. In conclusion, sex in local Saudi chickens in summer season influenced on TEC, TLC and PCV. These results can be a guide for scientists in the Kingdom of Saudi Arabia on changes of hematological and some biochemical value during hot the summer season.
