Abstract

The effects of temperature on rheological properties of livestock waste slurries was examined experimentally. The slurries had temperature ranging from 5 to 42.5°C. Apparent viscosity of the slurries was found to decrease as temperature increased, and increase as total solids increased. The activation energy (Andrade's equation) was determined for Hol-stain dairy cow, heifer, Angus, Kuroge, swine and poultry waste slurries.
