Abstract: Fourty Eight day old broiler chicks of Anak 2000 strain were used to determine the effect of an anitibiotic(Furazolidone) and antistress(Vitalyte) on production performance of broiler chickens. They were randomly assigned to four treatments comprising of Treatment 1(T1:control), Treatment 2(T2:antibiotic and antistress), Treatment 3(T3:Antibiotic) and treatment 4(Vitalyte). Results obtained from the study showed no significant differences (P>0.05) in final weight, feed intake, feed conversion efficiency and live weight gain between weeks four to nine. Inclusion of antibiotics and antistress in broiler diets over the five week period did not improve performance.
