초록

The aim of this study was to investigate the effect of manure additives mixed with probiotics and zeolite on harmful gas production generated by pig slurry. A total of 180 crossbred pigs ([Yorkshire × Land race] × Duroc, live weight 70±3.21 kg) were allotted to a completely randomized design with 3 treatments and 3 replications (20 heads per replicate). The treatments consisted of 0% (control), 0.05% (T1), or 1% (T2) of manure additives mixed with probiotics and zeolite. Manure additives were added weekly to pig slurry pits (2 m × 4.5 m × 1.2 m) on a volumetric basis. For ammonia measured at both 10 cm and 90 cm above the pig slurry pit, a statistical significance (p<0.05) was found in probiotics and zeolite-treated manure additives at weeks 1 - 3, except for week 0. In addition, hydrogen sulfide levels measured at 10 cm above the pig slurry pit were not affected by the manure additive at weeks 0 and 1, but showed a significant statistical difference at weeks 2 and 3 (p<0.05). Therefore, supplementing pig slurry with 0.05% and 0.1% manure additives mixed with probiotics and zeolite was found to be effective in reducing environmental pollution in pig facilities.
