The efficiency of manure separation by a conveyor belt under a partially slatted floor for fattening pigs
was determined for two types of belts, a flat belt with an incline of up to 6 transversely and a concave
belt with an incline of up to 1 longitudinally. A 31.20% and 23.75% dry matter content of the solid fraction
was obtained for the flat and concave belt, respectively. The flat belt was more efficient at 6 than
other slope angles. The residence time of the manure on the two belt types influenced the separation efficiency
from a live weight of 63.00 kg upwards. The quantity of residue produced with this system was
reduced to 25–40% with respect to a pit system under slat. This could mean a remarkable reduction in
costs of storage, transport and application of manure
