Pigs were randomly allotted to one of four dietary treatments: (1) CON, basal diet, (2) T1, CON + 0.1% probiotics mixture, (3) T2, CON + 0.2% probiotics mixture, and (4) T4, CON + 0.3% probiotics mixture. Increasing dietary inclusion of probiotics mixture levels linearly increased average daily gain (ADG) and average daily feed intake (ADFI) during day 0每7 as well as ADG and gain to feed ratio (G:F) during day 8每21 (pˋ<ˋ.05). There was a quadratic effect in improving ADFI during day 0每7, day 22每42, and ADG during day 8每21 (pˋ<ˋ.05). In addition, increasing inclusion of probiotics mixture levels in the diets linearly increased (pˋ<ˋ.05) dry matter (DM), nitrogen (N), energy digestibility, and faecal Lactobacillus counts and decreased Escherichia coli counts and ammonia (NH3) emission. However, no significant differences were observed in ADG, ADFI, G:F during day 22每42, and day 0每42 except for a quadratic increase of ADFI for day 22-42 (pˋ<ˋ.05). Feeding the pigs with the diets containing different probiotics mixture levels did not affect the faecal hydrogen sulfide emission (p>.05). In conclusion, increasing inclusion of probiotics mixture up to 0.3% linearly improved growth performance during day 0每7 and day 8每21. Pigs fed the diets with probiotics mixture suplementation improved the nutrient digestibility, faecal bacterial enumeration, and decreased NH3 emission. Highlights Probiotics mixture supplementation increased growth performance and nutrient digestibility in weaning pigs. Increased fecal Lactobacillus and reduced E. coli counts. Reduced fecal ammonia emission that can contribute in reducing environmental pollution %U https://www.tandfonline.com/doi/full/10.1080/1828051X.2018.1537726
