Influence of Enterococcus faecium with and without xylanase to corn and soybean meal-based diet on growth performance, nutrient digestibility, blood profiles, and faecal microflora in growing pigs

A total of 120 pigs [Duroc × (Yorkshire × Landrace)], with an average BW of 25.22 ± 1.88 kg, were randomly allotted to 4 experimental diets based on initial BW and sex (six replicate pens/treatment; 5 pigs/pen) to determine the effects of Enterococcus faecium (EF) with and without xylanase in growing pigs. The experiment lasted for 6 weeks. Dietary treatments included CON, basal diet; EF1, CON + 0.002% (EF); EF2, CON + 0.005% EF; EX, CON + 0.002% EF + 0.01% Xylanase. During the overall study, pigs fed EX diet increased ADG and G:F compared to pigs fed CON and EF1 diets (P
