This study investigated the effect of yeast riched with hydrolyzed mannan oligosacharid and symbiotic on growth performance, blood parameters and carcasses charchtristics in weaning male lambs. This study was carried out in a completely randomized design with factorial arrangement of 3*2 with 6 replicates on 36 male lambs. Treatments included: 1-control without supplementation, 2-treatment containing 2.0 grams of synbiotic, 3-treatments containing 2.0 grams of oligosaccharide (prebiotic), 4-treatment containing 2.0 g of mannose oligosaccharide (prebiotic) and 2.0 g of synbiotic, 5-treatment containing 4.0 g of synbiotic and 6-treatment containing 2.0 g of mannose oligosaccharide (prebiotic) and 4.0 g of synbiotic in the diet per lamb. There was no significant difference between the treatments in terms of dry matter intake. Daily weight gain data showed that on days 30 to 60, 2.0 g of synbiotic and 2.0 g of prebiotic (P= 0.03), on days 60 to 90 of 4.0 g of synbiotic and 2.0 g of prebiotic (P= 0.03) and 2.0 g synbiotic and 2.0 g prebiotic (P= 0.02) were significantly higher on days 90 to 110 than other treatments. The best feed conversion ratio at days 0 to 30 and 30 to 60, at 2.0 g synbiotic treatment (P= 0.04) and at day 60 to 90 at 4.0 g synbiotic treatment and at day 0 to 110 trials was 2.0 g of synbiotic (P= 0.04). Concentration of glucose and HDL in 4.0 g synbiotic and 2.0 g prebiotic (P= 0.02), cholesterol and BUN concentration in control (P= 0.03) and total protein in 4.0 g synbiotic and 2.0 grams of prebiotic (P= 0.02) was significantly higher. There was a significant differences in pre-slaughter weight (P= 0.03), hot and cold carcass weight (P= 0.03), percentage of hot carcass (P= 0.02) and percentage of cold carcass (P= 0.01), thigh percentage, meat pH and TBARS significant differences were found. The final data analysis showed that in daily weight gain, feed conversion ratio and the quantitative and qualitative traits of carcass, treatment 4 containing 2.0 g of synbiotic and prebiotic supplement had better performance than other treatments.
