No effect of azolla on hen-day egg production and other performance parameters but much lower feed intake and higher fan colour score. Though the phosphorus content of Azolla at 0.3–0.6% dry weight (5–10 μmoles phosphorus per g fresh weight), is a bit higher than the normal values for most plants, 0.2–0.25% dry weight, that difference can be entirely put down to the very low proportion of non-living and structural tissues in A. ; Iyyar, E. A., 2006. The fish fed in ponds also had a more valuable fatty acid profile (lower n-3:n-6 ratio) (Abou et al., 2013). Azolla meal fed at 5, 10 or 15% replacing rice bran. It has been shown that Cd significantly disturbs ionic ... Nitrogen (N) removal by E. crassipes, Lemna minor and Azolla pinnata was 71.8%, 62.5% and 60.1%, respectively. is an aquatic fern consisting of a short, branched, floating stem, bearing roots which hang down in the water. Monocrop azolla has been used in China and Vietnam during winter and spring to produce nitrogen for the spring rice crop. It attracted international attention in the 1970s as a result of the oil crisis and the rising prices of fossil fuel-dependent N fertilizers. J. Agric. Performance decreased with increasing rate of azolla but a 20% rate was acceptable. Evaluation of Azolla plant as an alternative stockfeed source. Egypt. Azolla also contributes to maintaining soil fertility, by providing nutrient-rich humus through its decomposition (Lumpkin et al., 1985). Sci. Res., 46 (3): 268-271.

Association Française de Zootechnie, Becerra, M. ; Murgueitio, E. ; Reyes, G. ; Preston, T. R., 1990. Fresh azolla could replace 20% or more of a commercial broiler diet (Subudhi et al., 1978; Namra et al., 2010). Azolla is a highly productive plant. Indian Vet. Azolla can survive within a pH range of 3.5 to 10, but optimum growth is observed in the range of 4.5 to 7. Azolla meal as a supplemental feed ingredient for tilapias. Azolla and its multiple uses with emphasis on Africa. Azolla grows best in full to partial shade (25-50% of full sunlight). Feed Sci. and Salvinia molesta Mitchell.) Fresh azolla + 40 or 60% chicken grower mash. 4.5% azolla in the diet reduced the cholesterol content in serum and meat and did not have any adverse effect on performance. Azolla can substitute for sesame meal. 97.4 kg of fresh azolla produced 1 kg of live weight gain. A. ; Iyayi, E. A., 2006. It doubles its biomass in 3-10 days, depending on conditions, and yield can reach 8-10 t fresh matter/ha in Asian rice fields. Usually leaves have 3 points giving it the arrowhead shape but some are narrow and almost grass-like. Adoption of azolla by livestock farmers still faces important hurdles. Rural Dev., 17 (5), Prabina, B. J. ; Kumar, K., 2010. It did not prevent ovipositing of Anopheles sinensis but limited the emergence of adult insects (Lu BaoLin, 1988). Effect of Azolla (Azolla pinnata) based concentrate mixture on nutrient utilization in buffalo bulls. The entire plant body consists of metabolically active non-structural tissue (Wolverton and McDonald, 1980) and the low fiber content of the plant has a beneficial impact on digestibility when used in animal feed. Soybean meal, fresh sugarcane juice, palm oil and fresh azolla (16% of diet DM) supplemented or not with fish meal. In a project for the development of disadvantaged areas of Bidar District (India), azolla production for increasing output from dairying was found to have the second highest benefit:cost ratio after production of worms for vermicomposting (Desmukh et al., 2013). Grassl. Azolla supplementation was profitable due to savings on feed cost. Inclusion of dried azolla up to 15% increased performance though it depressed nutrient digestibility. Duckweed is a simple plant consisting of two to three leaf- or frond-like structures and a single root or root hair. How to Grow Duckweed. Effect of dietary inclusion of Azolla (, Balaji, K. ; Jalaludeen, A. ; Kannan, A., 2010. The estimated energy value (gas production method) of azolla for ruminants is moderate (ME 7.4 MJ/kg DM) though in vitro DM digestibility is high (80%) (Parashuramulu et al., 2013). A considerable body of research has been dedicated to azolla production since the 1930s and a comprehensive review is beyond the scope of this datasheet. It has been empirically observed, and well appreciated by rice farmers, that azolla suppresses the growth of some aquatic weeds by forming a thick mat that deprives weed seedlings of sunlight while mechanically preventing them from emerging (Lumpkin et al., 1985; Van Hove et al., 1996).

K. ; Ashok, M. ; Thirumalesh, T. ; Umesh, B. U. ; Nataraju, O. R., 2013. 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). Becerra, M. ; Murgueitio, E. ; Reyes, G. ; Preston, T. R., 1990. Rural Dev., 14 (1): 1-6. Philippine J. Vet. In spite of the long recorded utilization of azolla in ruminants, data are still scarce.
