Résumé
One hundred and twenty, day old age healthy cobb broiler chicks were used to study the influence of dietary supplementation of enzymes on growth performance, immune response, some blood parameters and carcass traits of broiler chickens. Broiler chicks were allotted into four groups; chicks of group 1 [the control] were fed on basal diet only, chicks of group 2 were fed on the basal diet supplemented by Deltazyme plus [registered sign] at 0.5 g/kg diet, chicks of group 3 received 95%basal diet +5% wheat bran and chicks of group 4 received the same diet of group 3 supplemented with Deltazyme plus [registered sign] supplementation improved significantly [P 0.05] increased in chicks of group 4 when compared with those of group 3. Dietary enzymes supplementation [groups 2 and 4] reduced daily feed intake when compared with those groups 1 and 3 respectively. Dietary supplementation of Deltazyme plus [registered sign] at 0.5 g/kg diet improved significantly [P
