Abstract

The objective of this study was to determine the effect of dietary aspirin on performance, health
status of broilers reared in high density (15 birds / m 0) . Ninety chicks 7 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. Live body weight, weight gain , feed consumption , feed conversion ratio and mortality due
to ascites biweekly were recorded , also activity of some blood enzymes included GOT , GPT and ALP
at 7 weeks of age . The data obtained revealed the following :
Adding 0.2 % of aspirin in diet (T2) enhanced performance of broiler chicks compaired with control
(T1) when reared in high density and the enhancement started at week 5 , dietary aspirin increased live
body weight , weight gain , feed conversion ratio and decreased total mortality and mortality due to
ascites , also dietary aspirin decreased ascites syndrome through decrease of liver and heart weight
percentages and decrease the activity of GOT and GPT at 7 weeks of age . Adding 0.2 % of aspirin in
broiler diet are recommanded to reduce crowding stress and ascites syndrome during high density
production.
