This study was conducted to evaluate the effects of functional ingredients with supplementation as a bulking agent in composting of swine manure. Treatments were T1 & T5；Swine mature+Vermiculite, T2 & T6；Swine manure+Perlite, T3 & T7； Swine manure+Vermiculite+Perlite, T4 & T8；Swine manure+Bark. T1, T2, T3 and T4 were supplemented with functional ingredients on d 0 of composting. T5, T6, T7 and T8 were supplemented with functional ingredients on d 3 of composting. Functional ingredients were Fermkito and Yucca. During the composting period, changes of temperature were showed traditionally composting trend. Volatile fatty acids were decreased regardless of treatments in functional ingredients supplementation. Organic matter, T󰠏N and C/N ratio were showed higher bark treatments than other treatments. pH and EC were not differences among the treatments. P₂O₅ and K₂O were showed level of 1󰠏3%. In heavy metal, Cr were showed higher in vermiculite treatment than other treatments. In conclusion, vermiculite and perlite treatments were greater composting effects than bark.
