Abstract

Experiments were carried out to evaluate the anti- bacterial effect of formaldehyde solution 40%, two commercial formic-propionic acid mixture, antibiotic preparation and physical treatment against salmonella microorganism in artificially contaminated feed.
Formaldehyde solution 40% gave the best results of reduction (100% reduction) after one hour of treatment (10L/ton) and 3 hours of treatment for a concentration of (5L/ton). After 48 hours of treat- ment, the results obtained were relatively close to each other (98.1% for antibiotic preparation, 98.7&99.3% for organic acid preparations and 99.4% for physical treatment). However, the four treatments gave a complete decontamination of feed after 72 hours.
