Abstract
This study was performed to investigate the effect of beet plup and IRG (Italian ryegrass) dry powder in fattening pig diet on reducing concentration of odorous compounds in the pig slurry. Fifty fattening boars [(Landrace ${\times}$ Yorkshire) ${\times}$ Duroc] were randomly assigned to one of 3 treatments (control, beet plup 5%, and IRG 5%). Pigs (BW 50~110 kg) were fed diets formulated to meet the Korean Feeding Standard (2012) and their excretion was collected from the slurry pits. Short chain fatty acid (SCFA) and branched chain fatty acid (BCFA) were higher in beet plup (31,786, 3,985 ppm) and IRG (32,755, 4,261 ppm) treatments, which was not different among treatments (p>0.05), compared to control (p<0.05). Concentrations of phenols and indoles were highest in beet plup (183.83, 168.59 ppm) and IRG (9.32, 8.92 ppm) treatments. Altogether, addition level of two contents was not appropriate to decrease concentration of odorous compounds.
