N2  - Two hundred and forty unsexed one day-old Hubbard broiler chicks were used up to 6 weeks of age to study effects of probiotic. prebiotic, and their combination (symbiotic) on groWth performance and some blood metabolities. Chicks were divided into 6 treatments, each with 5 replicates of 8 chicks each. Starter (1-14 days) and grower (15-42 days of age) diets were ad lib fed. Treatments were the control (T1): probiotic (Bio-plus2B®, 400g/ton diet, T2); prebiotic (Techno Mos®. 500g/ton diet. T3): and three symbiotic treatments (200 and 250g/ton (T4). 400 and 500g/ton (T5). and 800 and 500g/ton diet (T6). for Bio-plus2B® and Techno Mos®. respectively). Effect of treatments on body weight and gain was only significant at grower period. Symbiotic treatments at recommended (T5) or high level (T6) significantly (P < 0.05) increased body weight and gain at 6 weeks of age. while the effect Of symbiotic at low level (T4) was not significant. Similar trend was observed with the full period (0.6 weeks). The solely addition of either probiotic (T2) or prebiotic (T3) had a significant (P < 0.05) reduction in hody weight and gain in comparison with the recommended symbiotic (T5)
