Implication

Randomized trial finds bacterial-enzyme treatment improves slurry quality in pigs, indicating benefits for air quality.

Key Points

  • The study aimed to assess the impact of bacterial-enzymatic bioactivators on ammonia emissions and slurry quality in pigs.
  • Involved 980 pigs categorized into control (CTR) and treatment (TRT) groups for 63 days
  • Collected slurry samples at three time points (T1, T2, T3)
  • Analyzed slurry characteristics including biochemical oxygen demand and microbial community changes.
  • TRT resulted in significantly lower ammonia, nitrogen, and pH levels at the second sampling (T2) with p<0.05
  • BOD₅ and COD levels were lower in TRT compared to CTR at study completion, p<0.05
  • Diverse microbial shifts observed, with Lactobacillus enriched in TRT and Clostridium in CTR.
