This study was conducted to compare the effect of dietary supplementation of SuperYea, SuperYea mixture with single, double and multi-strain microbes on growth performance, nutrient digestibility and fecal noxious gas content in growing pigs. One hundred and forty female pigs (24.00 ± 0.50 kg) were divided into 5 treatments with 6 replicates of eighteen pigs each and analyzed by completely randomized design (CRD). The diets were composed by Treatment I) basal diet+SuperYea, Treatment II) basal diet+SuperYea+Bacillus subtilis (1 × 1012 CFU), Treatment III) basal diet+SuperYea+Saccharomyces cerivisae (5 × 109 CFU), Treatment IV) basal diet+SuperYea+Bacillus subtilis (1 × 1012 CFU)+Lactobacillus lactis (1 × 1011 CFU) and Treatment V) basal diet+SuperYea+Bacillus subtilis (1 × 1012 CFU)+Lactobacillus lactis (1 × 1011 CFU)+Saccharomyces cerivisae (5 × 109 CFU). The results of the experiment showed that pigs fed with mixture of SuperYea and multi-strain microbes in diets showed heavier final body weights (67.20, 66.85, 65.44, 65.42, 65.47), body weight gain (42.80, 41.60, 40.99, 40.97, 40.97) and average daily gain (668.49, 660.32, 650.63, 650.32, 650.32) than another diets (P<0.05). The dry matter digestibilities of SuperYea mixed with multi-strain microbes were higher (P<0.05) than single strain treatments (86.53, 85.79, 84.40, 84.37, 84.44). The crude protein digestibilities were increased (P<0.05) with supplementation of multi-strain microbial in diet than another treatments (4.56, 4.46, 4.32, 4.30, 4.35). In conclusion, dietary inclusion of multi-strain microbes could be improve growth performance and nutrient digestibility and the decrease of ammonia in faecal.
