The aquatic plant Azolla filiculoides was grown in nine tanks of total area 468 m-? and fed as partial replacement (0, 15 and 30%) of the protein in a soyabean-based supplement given in restricted quantities (200 g protein/animal/daily) with fresh sugar cane juice to growing-fattening pigs. The trial was done on a commercial farm in the Cauca Valley in Colombia (1000m above sea level; mean temperature 24?C and rainfall 1100mm).
