ABSTRACT:
A method and apparatus for collecting and drying animal droppings at room temperature to substantially prevent the decomposition of the protein and urea therein. The droppings are collected on boards positioned beneath cages for the animals, and air at ambient temperature is forced over the droppings. The dried droppings are periodically turned and removed by raking apparatus which moves over the boards and either forces the droppings down tubular means to a conveyor below or sucks the droppings from the boards with vacuum.
