The objective of this work was to study the poultry litter composting and evaluate the physico-chemical and microbiological transformations as a time-function. At the end of composting, an increase of humification matter, a decrease of microbial diversity and the elimination of pathogens were observed. Results showed that poultry litter was liable of composting, without any nutritional complementation or inoculation and the process occurred similarly to other kind of organic residues.
