The objective of this study was to assess the effects of dietary carbohydrases on growth performance, nutrient digestibility and blood characteristics in finishing pigs. A total of 90 pigs [(Landrace ${ imes}$ Yorkshire) ${ imes}$ Duroc] (initial BW = $56.15{pm}1.26kg$) were used for a 35 d feeding trial. The dietary treatments included: 1) CON (control diet), 2) MIX (CON + mixture with ${alpha}$-galactosidase and ${eta}$-mannanase 0.05%) and 3) MAN (CON + ${eta}$-mannanase 0.05%). There were six replications per treatment with five pigs per pen. The average daily gain (ADG) in MIX was higher than in CON (p<0.05). No significant differences were noted in the average daily feed intake (ADFI) and feed efficiency (G:F) among dietary treatments (p>0.05). Apparent total tract digestibility (ATTD) of dry matter (DM) and energy (E) in MIX increased (p<0.05) relative to CON and MAN. The ATTD of nitrogen (N) in MIX was higher (p<0.05) than in CON. No differences in red blood cells (RBC), white blood cells (WBC), lymphocytes and IgG concentrations were observed among dietary treatments (p>0.05). In conclusion, the addition of the mixture of carbohydrases (${alpha}$-galactosidase and ${eta}$-mannanase 0.05%) increased ADG and nutrient digestibility in finishing pigs.
