Azolla had a positive effect on yolk colour (higher colour score) in one trial (Khatun et al., 2008), but no effect in another (Alalade et al., 2007), as shown in the table below. Human activities have, in general, resulted in much higher flows of minerals and organic materials through aquatic systems, often leading to eutrophication and a huge drop in the biomass produced in such systems. Azolla as a nutritionally rich cost effective and immuno-modulatory feed supplement for broilers. Effect of different types of plants (, Oren Benaroya, R. ; Tzin, V. ; Tel-Or, E. ; Zamski, E., 2004. 50% of groundnut meal protein was replaced by (fresh) azolla protein, Replacement of 30% of groundnut meal with dried azolla. Because azolla has a higher protein content (19-30%) than most green forage crops and aquatic macrophytes, and an essential amino acid composition (notably lysine) favourable for animal nutrition, azolla can be a valuable protein supplement for many species, including ruminants, poultry, pigs and fish (Hasan et al., 2009). Duckweed is a simple plant consisting of two to three leaf- or frond-like structures and a single root or root hair.

The bulkiness of fresh azolla is another limitation to its use in livestock diets and it is often preferable to dry it. It is also a source of green manure for upland rice growing on the most fertile soils that farmers are reluctant to use for legume crops. They give the appearance of a dark green to reddish carpet, except Azolla nilotica that does not produce the red anthocyanin pigment. Preference studies carried out in aquaria indicate that cichlids (Oreochromis, Tilapia and Cichlasoma) as well as a grass carp x bighead carp hybrid tend to prefer Azolla caroliniana (Antoine et al., 1986; Lahser, 1967; Fiogbé et al., 2004; Micha et al., 1988).

Monocrop azolla has been used in China and Vietnam during winter and spring to produce nitrogen for the spring rice crop. Duckweed is an aquatic plant that is commonly found in lakes, forming what seems to be a green blanket over the water. This technique is designed to grow azolla before planting the rice crop, allowing production of added nitrogen for the crop through cultivation of intercropped azolla (Lumpkin et al., 1985).
