The performance of electrocoagulation (EC) technique for decolorization and chemical oxygen demand (COD) reduction of anaerobically pretreated poultry manure wastewater was investigated in a laboratory batch study. Two identical 15.7-L up-flow anaerobic sludge blanket (UASB) reactors were first run under various organic and hydraulic loading conditions for 216 days. Effects of operating paramet...

In recent years the topic of food safety in relation to products of poultry origin mainly concentrated on Salmonella contamination. This paper will concentrate on the results of an experiment in which the shedding pattern of Salmonella enteritidis after oral challenge of broilers fed Flavomycin® were compared with a zerocontrol group. In addition to this the effects of inclusion of this product...
