The objective of this study was to determine the effect of adding aspirin to the diet on some
biochemical parameters such as blood serum glucose , cholesterol , uric acid , total protein ,
phosphorus and calcium concentrations of broilers reared in high density (15 birds / m ) . A 90 chicks 7
days old were distributed into two treatments (45 chicks per treatment ) , T1 chicks fed a diet without
aspirin (control) , chicks in T2 fed a diet supplemented with 0.2 % aspirin (2 mg aspirin / kg feed) .
Each treatment subdivided into three replicates and each replicate reared in 1 X 1 m pen . The data
obtained revealed the following:
Blood serum glucose concentration were 189 mg /100 ml , cholesterol concentration were 207
mg /100 ml , uric acid concentration were 4.6 mg /100 mll of T1 chicks at 7 weeks of age , adding 0.2
% of aspirin to the diet (T2) decreased blood serum glucose , cholesterol and uric acid of broiler chicks
to 178 , 182 and 4.2 mg /100 ml respectively , in the same time adding aspirin to the diet increased
significantly (P<0.01) total protein concentration which were 5.1 gm /100 ml compaired with 4.6
gm/100 ml of control chicks (T1) at 7 weeks of age . Adding aspirin to the diet increased significantly
(P<0.01) blood serum phosphorus and calcium concentrations which indicated the importance of
adding aspirin in broiler diet to rebalance blood biochemical parameters and reducing crowding stress
during high density production
