Description 199-205
There is scanty information about the microbial composition of poultry manure processed through several bioprocessing
interventions such as anaerobic digestion (AD) and vermicomposting. Here, we investigated the changes in microbial
population and parasitic load of poultry manure (both litter and excreta separately) undergoing AD and vermicomposting .
The study was conducted for a period of three months. Six biogas digesters and seven vermicompost units were used
comprising of different treatments. Broiler litter was pretreated with 0.1 and 0.2 mol/L NaOH prior to AD while the layer
excreta was subjected to different dilutions in water (1:6, 1:8, 1:10) for the production of biogas. Further, the substrates were
also used for vermicompost production wherein similar treatment was given to the broiler litter while different carbonaceous
materials (16-20 kg of leaves, rice husk, saw dust and wheat straw per 100 kg of poultry waste) were incorporated to the
layer excreta. The microbiota changes were studied which comprised of changes in total bacterial count (TBC), coliform
count and Salmonella spp. count in all the treatments at regular intervals. The parasitic load was also measured by counting
eggs per gram (EPG) in all the treatments at regular interval. The results of the study showed a significant (P
