The research was conducted on 180 commercial Muong-Te pigs to aim at evaluating the effect of supplementing probiotics in the diet on diarrhea syndrome, carcass performance and productive efficiency. The experiment was carried out at Ung-Thin Cooperative, Seo Village, Kan-Ho commune, Muong-Te district, Lai-Chau province from March 2023 to January 2024. The experiment was divided into 2 control groups (no supplementation) and experimental groups (0.5% Probiotics mixture was added to concentrate), each group consisted of 90 pigs and divided into 10 pens. The experiment was designed as a completely randomized block, ensuring uniformity in initial body weight and sex of the pigs. Data analysis used the GLM model in Minitab16, comparing levels using the Tukey method with the level a=0.05. The results showed that pigs supplemented with the Probitotics mixture were well controlled for diarrhea syndrome, whereas the control group had diarrhea incidence of 11.11%. The experimental group reduced productive cost by 1.98%. Carcass traits increased from 1.20% (Lean meat percentage of 42.25% compared to 41.75%) to 7.13% (slaughter weight), fat percentage decreased by 1.87%, skin proportion decreased by 1.06%. It is concluded that supplementation of Probiotics mixture into the ration of commercial Muong-Te pigs reduced diarrhea syndrome, positively affected productive efficiency and carcass performance. commercial Muong-Te pigs fed with probiotics mixture had a lean meat percentage of 42.25%.
