Procedure for centrifugal fecal flotation - DVM 360
Joyce S. Knoll, VMD, PhD, DACVP. A quick step-by-step to performing this procedure. 1. Mix about 2 to 5 g of feces with 10 ml flotation solution, and pour the mixture through a tea strainer into a cup. For ease of cleaning, the tea strainer can be lined with a 4-x-4-in gauze square. 2. Pour the strained solution into a 15-ml centrifuge tube.

The pebble product is usually of sufficient purity as a final product, and the flotation feed is subject to the standard Crago process to achieve low-insol product. However, in some Florida operations, the 16 by 150 mesh fraction is sized at 35 (or 28) mesh, with the
