This study was conducted to evaluate effects of dietary pine cone meal on growth performance, blood characteristics, carcass quality and fecal noxious gases compounds in finishing pigs. The total of sixty [(Landrace×Yorkshire)×Duroc] pigs(86.01±0.25kg in average initial body weight) were used in 35 days assay. Dietary treatments included 1) T1(2% cottonwood sawdust), 2) T2(1% cottonwood sawdust+1% pine cone meal) and 3) T3(2% pine cone meal). There were three dietary treatments with five replicate pens per treatment and four pigs per pen. During the overall periods, there were no significant differences in ADG(Average daily gain), ADFI(Average daily feed intake) and gain/feed ratio among treatments (P>0.05). Also, Nutrient digestibilities and blood characteristics were not affected by dietary treatments. At the end of this experiment, a*-value of logissimus dorsi muscle color and sensory evaluation color were higher in T3 treatment than T1 treatment(P<0.05). In fatty acid contents of lean, C18:1 and total MUFA were significantly lower in T1 treatment than other treatments(P<0.05). However, total ω6 and total PUFA were higher in T1 treatment than T2 treatment(P<0.05). In fatty acid contents of fats, total SFA was significantly higher in T2 treatment than T3 treatment(P<0.05). C18:1 was higher in T2 treatment than T1 treatment(P<0.05). There were no significant differences in fecal noxious gas compounds among the treatments. In conclusion, the results of the experiment was affected by dietary supplementation of pine cone meal on meat color and fatty acid composition of pork in finishing pigs.
