  Effects of a probiotic (PRIMALAC) and a prebiotic (FERMACTO) on performance, ileum and crop microbial flora and carcass characteristics have been examined on 480 1 day old Ross 308 broiler chicks. The experiment carried out in a factorial design including three levels of FERMACTO (0, 1 and 2 g ton-1) and two level of Perimalac (0 and 900 g ton-1). Each of treatment was allocated to 5 replicates of 16 male broilers and reared for 42 days. The microflora population in crop and ileum parts was measured on appropriate bacteriological media. Results of experiment indicated that application of primalc (900 g ton-1) significantly improved body weight gain and feed conversion ratio (p<0.01). Feed consumption and feed conversation ratio were not affected with supplementation of different levels of FERMACTO. The percent of carcass, thigh, breast and abdominal fat were not affected by treatments. Coliform counts in the ileum of birds receiving PRIMALAC (900 g ton-1) and FERMACTO (2000 g ton-1) were significantly lower than those of the control birds (p<0.05). Different levels of PRIMALAC or FERMACTO had no effect on total bacteria counts in the ileum and crop parts. In 3rd week of rearing periods, the highest significant (p>0.05) value of lactobacilli population was recorded for broilers fed diet supplemented with PRIMALAC (900 g ton-1) but different levels of FERMACTO relatively increased lactic acid bacteria population in crop. The results of present study revealed that these feed additive by acting on microbial population of digestive system significantly (p<0.05) affects broiler performance.

  An experiment was conducted to evaluate the effects of different levels of probiotic and prebiotic on growth performance and carcass characteristics of broiler chickens. About 480 sexed male Ross 308 hybrid chickens were used. The birds were assigned six treatment groups in a randomized complete block design. Each treatment allocated to 5 replicates of 16 male broilers and reared for 42 days. The broiler chickens were grown on starter (0-21 days) and grower (22-42 days) diets calculated to meet NRC recommendations and supplemented with different levels of probiotic PRIMALAC (0, 900 g ton-1) and prebiotic FERMACTO (0, 1000 and 2000 g ton-1). Body weight and feed consumption were determined weekly during the study. Each dietary was fed ad libitum in the whole of experiment. The result of present study showed that the interaction effect between different levels of PRIMALAC and FERMACTO was significant. The highest value of body weight gain was recorded for broilers fed the diet supplemented with mixed of PRIMALAC (900 g ton-1) and FERMACTO (2000 g ton-1) (p<0.05). Lowest feed conversion ratio was belonging to prebiotic (2000 g ton-1) group and caused more efficient feed intake. The highest significant (p<0.05) value of carcass and breast were recorded for broilers fed diet supplemented with mixing PRIMALAC and FERMACTO. The percent of carcass, thigh and abdominal fat were not affected by treatments. The results of present study revealed that supplemented diets with mixed of PRIMALAC and FERMACTO (symbiotic) as growth promoters appeared to be superior compare to use alone and improve broiler chickens growth indices.
