Abstract

The present experiment was carried out in order to investigate the effect of polyzyme (multi enzymes) in broiler diets with low protein levels on growth performance, carcass traits, some blood components and economic efficiency. A total of 180 Ross 308 unsexed one - day old broiler chicks, were distributed at random into 3 groups each in 3 replicates, 20 chicks each. Treatments were: T1: positive control, without Polyzyme, T2: negative control, without Polyzyme and T3: negative control, with o.5 g Polyzyme/ kg diet through the starter (1- 21 d) and finisher (22- 35 d) period. Results revealed that, chicks fed the negative control with polyzyme addition had significantly (P ≤ 0.05) higher body weight, body weight gain and performance index, while daily feed intake decreased. Feed conversion ratio, European efficiency index and economic efficiency improved also with the supplementation. Dressing, liver and heart % were increased in the same treatment (T3), while gizzard % was not affected.   Polyzyme supplementation to low protein diet decreased serum total cholesterol and increased aspartic transaminase (AST) enzyme compared to the positive control (T1), meanwhile total protein, creatinine, glucose and alanine transaminase (ALT) enzyme were not affected, indicating the safety use of polyzyme at the level of 0.5 g/ kg diet. Data indicated that the beneficial economical effect of using polyzyme with low protein diet is to reach almost the same performance with normal protein diet.
