Successful utilisation of animal excreta is dependent on knowledge of the characteristics of the material. Most of the published reports are confined to analyses of samples collected over a relatively short period of time and give little information on the variability of parameters such as suspended solids, chemical oxygen demand, biochemical oxygen demand, or plant nutrient content. During studies on the biological treatment of animal wastes, samples of fresh slurry have been analysed at frequent intervals over a prolonged period. This report presents a summary of analyses of a slurry of excreta (faeces and urine) from fattening pigs, collected approximately twice per week between 1973 and 1977. Piggery slurry is then compared to the analyses of a slurry of poultry excreta, diluted to a similar solids concentration, collected weekly throughout 1973. due to the similarity of the two types of excreta it is concluded that if slurry systems of animal waste management are adopted for pigs and poultry, then methods of handling and treatment can be developed that are applicable to both types of material.
