Effects of times of collection and different storage methods on the microflora and nitrogen content of poultry waste.
An experiment was conducted to determine the effects of times of collection and storage methods on the kinds and numbers of microflora and nitrogen content of poultry excreta (waste). Fresh waste collected in the morning had a higher mean count of viable bacteria than the evening collection in both strains of hen studied. Fresh waste samples had higher mean counts than dried ones. Escherichia coli and Proteus spp. were the predominant microflora identified in waste collected at both times from both strains. Collection time had no effect on the type of micro-organisms isolated. Bacillus spp. was least frequently isolated in fresh waste but most often in dried waste. Samples of waste collected in the morning from Babcock layers contained more nitrogen than those collected in the evening. Samples collected in the morning from Warren layers and stored under aerobic conditions had the highest nitrogen content. However, there were no significant differences in the nitrogen content of waste from Babcock layers attributable to storage method.
