Azolla spp

Azolla (Azolla spp) is a genus of seven species of aquatic ferns in the family Salviniaceae; these include A. caroliniana, A. filiculoides, A. microphylla, A. mexicana, A. nilotica and A. pinnata. Azolla is a small free-floating fern with floating stems that hang down in the water. It can vary in color from green to reddish-brown. Azolla appears similar to duckweed and is grown in quiet ponds that are protected from wind.

Azolla was initially used as a feed for poultry in Peru in the 18th century. It is high yielding and highly nutritious, making it an excellent fodder for ducks and waterfowl. Azolla can be fed to birds in fresh or dried form, however it quickly perishes in fresh form. It contains 20-28% highly digestible protein, and is rich in essential amino acids, vitamins, and minerals. Azolla is an organic, low cost, nutrient-rich waterfowl and poultry feed.
