Effect of concentration of dietary Aspirin (Acetylsalicylic acid) on chickens blood parameters in summer season

Abstract

The objective of this study was to determine the effect of dietary aspirin on some chickens blood parameters includes Packed Cell Volume (PCV), Hemoglobin (Hb), Red Blood Cells (RBCs), White Blood Cells (WBCs), Sodium and Potassium concentrations in summer season. A 180 chicks 7 days old were used as an experimental animals and distributed into four treatments (45 chicks per treatment ), T1 chicks fed a diet without aspirin (control) , chicks in T2 fed a diet supplemented with 0.05 % aspirin, chicks in T3 fed a diet supplemented with 0.1 % aspirin, chicks in T4 fed a diet supplemented with 0.2 % aspirin. Each treatment subdivided into three replicates and each replicate reared in 1 X1 mpen . The data obtained revealed the following :

    T1chicks had high blood parameters values, PCV were 35.4 and 36.8 %, Hb were 7.3 and 8.5 mg /100 ml, RBCs were 34.7 and 36.9 million cell / ml, WBCs were 24.1 and 25.8 thousand cell / ml at 4 and 7 weeks of age respectively, adding 0.2 % of aspirin to the diet (T4) rebalance blood parameters values through decreased PCV which were 34.1 and 34.8 %, Hb were 6.8 and 7.4 mg /100 ml, RBCs were 33.6 and 34.3 million cell / ml, WBCs were 22.6 and 23.2 thousand cell / ml at 4 and 7 weeks of age respectively. Adding 0.2 % of aspirin to the diet increased significantly (P<0.01) blood serum sodium and potassium concentrations, no differences in blood parameters values were appeared due to adding 0.05 and 0.1 % of aspirin to the diet (T2 and T3), which indicated the importance of dietary 0.2 % of aspirin to rebalance blood parameters values and reducing heat stress during summer season.
