“…Some researchers explored charcoal as an animal's feed additives. Dietary supplemented with charcoal affected growth performance and carcass traits in fattening pigs (Hwang, 1995), and it also affected microbes reproduction in sheep (Knutson et al, 2006), meat quality and storage characteristics of pork (Hwang, 1995). Charcoal controls the lactic acid concentration by maintaining the pH level and microflora population in rumen animals (Hoshi et al, 1991).…”

The purpose of this study was to investage the effects of dietary bamboo charcoal on the carcass characteristics and meat quality of fattening pigs. Fifty four crossed pigs of 61.0±1.0 kg body weight (BW) were grouped and housed in 6 animals (3 barrows and 3 gilts) per pen and 3 replications per treatment. The basal diet (C) was supplied with 0.3% bamboo charcoal as treatment 1 (T1) and 0.6 % as treatment 2 (T2). The pigs were fed that experimental diet for 42 days, thereafter 10 longissimus dorsi (LD) per treatment were randomly collected at the time the pigs reached an average weight of 110.0±5.0 kg. The carcass weight, backfat thickness, and the carcass grade were better (p<0.05) in the pigs fed bamboo charcoal than in C. The crude fat concentration of LD was higher (p<0.05) in T1 than in C. While the composition of stearic acid and arachidonic acid was lower (p<0.05) in treatments than in C, the composition of oleic acid and linoleic acid of treatments was higher (p<0.05) than C. The physico-chemical characteristics, such as meat color and amino acid composition of LD were not affected (p>0.05) by the supplemented bamboo charcoal. In conclusion, dietary supplementation with bamboo charcoal improved the carcass grade and fatty acids composition of pork meat from fattening pigs, where the composition of unsaturated fatty acids was increased, but that of saturated fatty acids was decreased.

This study was carried out to investigate the effects of bamboo charcoal and bamboo vinegar as alternatives of antibiotics in the diet of fattening pigs and their influence on growth performance, immune responses and fecal microflora populations. Crossed pigs (n = 144, 79 kg body weight) were divided into 12 heads per pen, four diets and three replications. The basal diet (negative control: NC) was supplemented with 0.3% antibiotics (positive control: PC), 0.3% bamboo charcoal (BC) and 0.3% bamboo vinegar (BV). Average daily weight gain and feed efficiency were higher (P < 0.05) in PC, BC and BV. The concentration of lactate dehydrogenase and cortisol were lower (P < 0.05), but the concentration of immunoglobulin G (IgG) and IgA were higher (P < 0.05) in PC, BC and BV. Counts of coliform bacteria and Salmonella spp. were lower (P < 0.05), while the counts of fecal anaerobic total bacteria and lactic acid bacteria were higher (P < 0.05) in PC, BC and BV. A reasonable inclusion of bamboo charcoal or bamboo vinegar as antibiotics in the diet of fattening pigs leads to a better growth performance, immune responses and fecal microflora populations. The results of the present study suggest that bamboo charcoal or bamboo vinegar could be a potential additives in animal production as an alternative to antibiotics.

“…Charcoal affected growth performance and carcass traits in fattening pigs (Hwang, 1995), and was used as feed additive for production of high-quality meat (Kim, 1990). Activated charcoal also affected microbe reproduction in sheep (Knutson et al, 2006) and meat quality and storage characteristics of pork (Lee et al, 2011). In this study, the digestibility of organic medicinal charcoal on dry matter was higher than that of basal diet in vitro.…”

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 (NH 3 , H 2 S, 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 H 2 S 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.
