An experiment was conducted to assess effects of Enterococcus faecium and a blend of organic acids (OAs) and medium-chain fatty acids (MCFAs) in finishing pigs. A total of 120 pigs [Duroc x (Yorkshire x Landrace); 51.04 +/- 1.82 kg] were randomly assigned to five dietary treatments: CON, basal diet; BOM1, CON + 500 mg kg(-1) blend of OAs and MCFAs; BOM2, CON + 1000 mg kg(-1) blend of OAs and MCFAs; EBOM1, BOM1 + 20 mg kg(-1) E. faecium; EBOM2, BOM2 + 20 mg kg(-1) E. faecium. Pigs fed EBOM1 and EBOM2 diets had higher average daily gain and average daily feed intake (during days 36-70 and days 1-70) and greater digestibility of dry matter (days 35 and 70) compared with those fed BOM1 and BOM2 diets (P < 0.05). However, no differences on blood parameters and meat quality were observed between pigs offered BOM1 and BOM2 diets and those fed EBOM1 and EBOM2 diets (P > 0.05). In conclusion, supplementation with the combination of E. faecium and a blend of OAs and MCFAs was more effective in improving growth performance and nutrient digestibility than supplementation with blend of OAs and MCFAs alone in finishing pigs.
