This study was conducted to examine the effects of dietary Mogchotan(the mixture of charcoal and pyroligneous acid, 80:20, w/w) supplementation on fattening performance, fatty acid composition and the physico-chemical characteristics of meat in pigs. The present study was also stressed to investigate the possibility of industrial utilization of charcoal and pyroligneous acid as a livestock feed additive. Weight gain and feed conversion in pigs fed the Mogchotan supplemented diet were higher than those of the control group. In fatty acids composition, palmitic acid(C16:0) contents of Mogchotan treatment groups were lower than that of control group. However, Mogchotan supplementation increased C16:1, C18:0, C18:1, C18:2 and C18:3 contents when compared with control group pigs. Also, Mogchotan supplementation groups decreased saturated fatty acids level than control group. On the other hand, Mogchotan supplementation showed higher unsaturated fatty acids value, especially polyunsaturated fatty acids value compared to control group. The carcass pH of pigs fed the Mogchotan tended to be higher than control, but was not significantly different. The water holding capacity was significantly higher in pigs fed the 3.0% Mogchotan-supplemented diet than those of other treatment groups(p<0.05). Altogether, it has been suggested that dietary $1{\sim}3%$ of Mogchotan supplementation improved the fattening performance and meat quality in pigs.

This study was examined to investigate the effect of wood carbonization products on growth and body composition of oliver flounder(Paralichthys olivaceus) as a part of fishery utilization of charcoal and pyroligneous acid. Weight gain in oliver flounder fed with wood carbonization products was higher than that of the control group. Feed efficiency between the groups fed with charcoal and Mogchotan(the mixture of charcoal and pyroligneous acid, 80:20, w/w) and the control group showed no significant difference(p>0.05) and was significantly higher in group fed with pyroligneous acid than the control group(p<0.05). All groups fed with wood carbonization products were also higher than the control group in hemoglobin and hematocrit. Especially, the amount of both components was significantly higher in group fed with Mogchotan(p<0.05). The result indicates that the addition of Mogchotan can improve the health of oliver flounder, and was excellent in the mortality and the recovery rate. In conclusion, Mogchotan treatment would be suitable way for improving the growth and health of oliver flounder.
