| Purpose: Poultry manure (PM) is a concern for Bangladesh. The improvement of quality and safety is always desirable. The experiment assesses the quality and safety parameters of PM with the addition of Saccharomyces cerevisiae and indigenous microorganisms (IMO) in different fermentation conditions (aerobic, facultative anaerobic, and anaerobic) for 7 days. Method: Fermentation condition × treatment factorial analyses were performed to explore their effect on the quality and safety of PM. The organoleptic quality (color, smell, and texture), pH, nutritional components (organic matter, crude fiber, crude protein, ether extract, nitrogen-free extract), in-vitro organic matter digestibility, metabolizable energy, mineral contents (phosphorus, potassium, sulfur), heavy metals (lead, copper), and microbial properties (total coliform count, E-coli, Salmonella) of fermented PM at 0, 3, 5, and 7 days were evaluated. Results: All parameters of the different treatments in different fermentation conditions changed significantly (P < 0.05) with increasing the fermentation time. All parameters were found desirable in 10% IMO treated PM. Organoleptic parameters (color, smell, and texture) were satisfactory in aerobic fermentation but other parameters were acceptable in anaerobic fermentation conditions. pH was dropped significantly (P < 0.05) with increasing the duration. Conclusion: To summarize all properties, it could be noted that the quality and safety of PM were improved after 7 days of fermentation with a fermentation mixture of PM (90%) and molasses (10%) inoculating 10% IMO under an anaerobic condition which could be used for animal feeding. | ||
