Effects of Dietary Pine Cone Meal on Growth Performance, Blood Characteristics, Carcass Quality and Fecal Noxious Gases Compounds in Finishing Pigs

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
