ABSTRACT
The purpose of this study was to assess whether two chemicals, paraformaldehyde, and potassium peroxy-monosulfate were effective in controlling the microbial load of nest bedding material as a first step in reducing contamination of broiler breeder hatching eggs. In a closed broiler breeder farm where birds were housed on built-up litter, the two disinfectants were used for the disinfection of nest bedding (sawdust). Paraformaldehyde powder was mixed manually with nest bedding (5 grams per nest), while potassium peroxy- monosulfate 0.5% based disinfectant was sprayed in each nest. Random samples were collected before and after treatment by 24-, 72- and 120-hours intervals and were tested for total bacterial, coliform, and fungal counts to evaluate the reduction percent achieved. The obtained results illustrated that neither disinfectant could achieve a complete reduction of the microbial load of nest bedding material. However, both disinfectants recorded a significant (p≤0.05) log reduction in total bacterial, coliform, and fungal count after 24, 72 and 120 hours, gradually. Conclusively, paraformaldehyde and potassium peroxy-monosulfate based disinfectants may be recommended for disinfection of nest bedding material to reduce the microbial contamination of hatching eggs.
