This study was performed to evaluate the effect of organic medicinal charcoal as a feed additive on aflatoxin absorption, odor emission, fecal microflora and in vitro digestibility in pig diet. A 10-day trial was conducted with 20 [(Yorkshire × Landrace) × Duroc] finishing pigs (BW = 81 ± 3.3 kg) to investigate the population of Lactobacillus and E. coli in feces and fecal odor (NH₃, H₂S, total mercaptans, and Acetic acid) in vivo. The in vitro and in vivo treatments included: control (basal diet; CON); (basal diet + 0.25% Organic Medicinal Charcoal; OMC); (basal diet + 0.50% Pyroligneous Charcoal; PC); and (basal diet + 0.50% Coconut tree Charcoal; CC). The aflatoxin absorption capacity was 100, 10, and 20% in OMC, PC, and CC, respectively. The digestibility of dry matter in OMC was significantly higher than that of CON, PC, or CC in vitro (p < 0.05). The digestibility of organic matter in OMC was found to be significantly different from that of CON (p < 0.05). Fecal ammonia and H₂S emissions of OMC were observed to be significantly lower than those of CON, PC, and CC (p < 0.05). Lactobacillus counts in feces of OMC and CC were significantly higher than those of CON and PC (p < 0.05). Fecal E. coli counts of OMC and CC were lower than those of CON and PC (p < 0.05). It was concluded that organic medicinal charcoal can be used as a feed additive in pig diets because it improves the digestibility of feed and fecal odor, and has positive effects on the population of microorganism in feces.
