| Research Abstract |
The purpose of this study is to establish a novel management of dairy manure by anaerobic digestion for ensuring the safety. We assumed the manure from dairy cows injected with veterinary antibiotics, and focused on the survival of antibiotic resistant bacteria during anaerobic digestion, and electrochemical inactivation of antibiotic resistant bacteria in anaerobically digested slurry. Results with manure samples from three different farms showed a similar trend that numbers of antibiotic-resistant bacteria decreased after the anaerobic digestion except for specific antibiotics. The electrochemical disinfection process decreased numbers of antibiotic-resistant bacteria in the anaerobically digested slurry. The result indicates that the batch mesophilic anaerobic digestion and electrochemical process can reduce relative risks of antibiotic-resistance bacteria in livestock manure.
