The aim of this study was to produce biological silage from chicken waste based on fermentation of autogenous bacteria and to evaluate the quality characteristics of the product. In order to produce this product, sampling was performed from selected slaughterhouses in Mazandaran province and biosilage was produced in the form of a one-ton fermenter using autogenous bacteria isolated from the region (fermentation). The final product (dried biosilage powder) was evaluated qualitatively using standard methods and compared with other sources including meat powder, blood powder and kilka fish powder (produced by batch method). The results showed that the amount of protein, fat and protein digestibility in the produced biosilage was 59.09%, 21.30% and 87.41%, respectively. The product produced was in a better condition than meat powder and kilka fish powder in terms of the mentioned indicators. The produced biosilage did not show a significant difference between blood powder in terms of calcium and phosphorus and was at a lower level than kilka fish powder and meat powder. The levels of TVN, PV and TBA in biosilage were measured as 46.56, 4.46 and 2.21, respectively. These indices are in a much more favorable condition in the produced product compared to Kilka meat powder and fish powder. It was further found that the microbial parameters (mold, yeast, coliform, fecal coliform, E.coli) in the samples of meat powder, blood powder and kilka fish powder were relatively higher compared to biosilage of chicken waste. According to the results of the present study, chicken waste has the ability to be converted into biosilage with desirable characteristics that can be used in agriculture and aquaculture industries.
