Abstract
The objective of this study was to determine the effect of dietary aspirin on performance of broilers reared in high density (15 birds / m 2) during summer. Ninety chicks 1 days old were distributed into two treatments , chicks in T1 fed a diet without aspirin (control), chicks in T2 fed a diet supplemented with 0.2 % aspirin. Each treatment was subdivided into three replicates and each replicate reared in 1 X 1 m pen for 7 weeks. Live body weight, weight gain, feed consumption, feed conversion ratio and mortality due to ascites were weekly recorded. The data obtained revealed the following :Adding 0.2 % of aspirin in diet significantly (P<0.05) enhanced performance of broiler chicks compared with control when reared in high density and the enhancement started at week 4 to the end of the study at week 7 , terminal live body weight were 1459.0 and 1640.0, cumulative weight gain were 1408.0 and 1589.3, total feed consumption were 2946.7 and 3237.2 and feed conversion ratio were2.09 and2.04 for T1 and T2 respectively. Also adding aspirin in broiler diet (T2) significantly (P<0.01) reduced total mortality to 17.78 % compared with 28.89 % in T1, and significantly (P<0.01) reduced mortality due to ascites to 2.22 % compared with 8.89 % in T1.
