摘要：

Changes in poultry litter's (aqueous extract) biochemical oxygen demand (BOD) and toxicity, to photobacterium phosphoreum, calculated as EC50 values, with the time of composting and the number of flocks raised, before cleaning the house, were studied. The BOD of the extract (5 g L-1) is comparable to that of raw sewage and it increased with the time of composting, following a first order kinetics. The extract showed a toxicity higher than the toxicity of a solution of 25 ppm phenol. Increasing the number of flocks raised (from 2 to 15), before cleaning the house, reduced both the litter's BOD (22%) and toxicity (66%). © 1990 Kluwer Academic Publishers.
