Slaughterhouse residuum (SR) was fermented under aerobic conditions for utilization as a feed source, and palatability to pigs was tested. Various amount of air were admitted at rates ranging from 0-15l/min, to determine the volume that would be best for the process. Moisture, pH, organic matter and bacterial number were examined before and after the process. Feed composition of fermented slaughterhouse residuum (FSR) were examined, and palatability was checked.The following results were obtained :1. In the fermentation of SR, the best aeration rate was 10l/min per SR 100kg.2. Escherichia coli and Salmonella counts were decreased through the heat generated (self-heating) by the fermentation.3. The FSR contained 12.9% crude protein and 24.4% crude as dry matter.4. FSR was found to be sufficiently palatable to the pigs. Even when it was increased to 60% by weight of the feed, there was no decrease in its consumption by the animals.
