What is your purpose of Azolla?
If it is cattle feed you cannot feed more than 1 Kg/day/animal.
1.have bricks lined up for 15'x20x1'. To use as a tank
2.fill sand on the bottom of the tank.
3. Use sipaulin sheet to line the tank.
4.Fill 10Kg seeved mud 5 Kg Cow dung
5. Fill water.
6. Prepare Shade on this tank.
7. Cautions to take are rain water should not flood into tank, Frogs or any other animals should not dwell in this tank. Mosquitoes should not lay eggs.
8. If you leave Azolla culture about 100Gm within aweek or two your tank will be full.
9. Wash azolla before feeding to cattle.
10. once in a month water has to be changed and cow dung and mud has be changed to avoid nitrogen accumulation.
After all these efforts you can feed only 1Kg for 1 animal. Is the efforts worth? The answer depends on individuals.
Since investment you are making is minimal you can find out how much vaible this for your condition.
By the way Azolla culture is available in your nearest KVK

Yes Azola can be used as nitrogen fertilizer. In paddy fields, azolla grows naturally to help paddy.
Even if you cannot smell the cowdung, cows can smell. You may have to mask the smell with jaggery or something stronger.
Frogs and mosquitos will destroy the azolla. Try to keep them away.
It is for all these reasons that Azolla is not such a viable solution to cattle feed.
For normal fields, you may have to dry and powder it to be useful.

Spirulina is a wonderful algae which takes care of anything. It's success is proved in poultry, sheep and goat, a great success in rabbitry and also cows. If you buy spirulina in the open market this is a costly affair. However, each calf requires 500 gms during the first month. It drives out all diseases of improper disgestion. If U grow of course You can add 1 to 2% in the feed. The best one is use azolla (dry 2 Kgs ) each cow, this will increase yield and you will be surprised to note the quality. Spirulina contains minimum of 65% protein and all essential amino acids.
Azola Production
--------------------------------------------------------------------------------
Azolla productionNARDEP has been working on azolla for the last three to four years, studying its potential as a feed and exploring cost effective methods for the mass multiplication of azolla in farmers’ homesteads.
Close-up view of an azolla plant. The size of the plants are 1 - 3 cm.
In our method, a water body is made, preferably under the shade of a tree, with the help of a silpauline sheet. Silpauline is a polythene tarpaulin which is resistant to the ultra violet radiation in sunlight. A pit of 2 x 2 x 0.2 m is dug as a first step. All corners of the pit should be at the same level so that a uniform water level can be maintained. The pit is covered with plastic gunnies to prevent the roots of the nearby trees piercing the silpauline sheet, which is spread over the plastic gunnies. About 10 - 15 kg of sieved fertile soil is uniformly spread over the silpauline sheet. Slurry made of 2 kg cow dung and 30 g of Super Phosphate mixed in 10 litres of water, is poured onto the sheet. More water is poured on to raise the water level to about 10 cm. About 0.5 - 1 kg of fresh and pure culture of azolla is placed in the water. This will grow rapidly and fill the pit within 10 - 15 days. From then on, 500 - 600 g of azolla can be harvested daily. A mixture of 20 g of Super Phosphate and about 1 kg of cow dung should be added once every 5 days in order to maintain rapid multiplication of the azolla and to maintain the daily yield of 500 g. A micronutrient mix containing magnesium, iron, copper, sulphur etc., can also be added at weekly intervals to enhance the mineral content of azolla.
Nutrient content and its impact on growthAzolla is very rich in proteins, essential amino acids, vitamins (vitamin A, vitamin B12 and Beta- Carotene), growth promoter intermediaries and minerals like calcium, phosphorous, potassium, ferrous, copper, magnesium etc. On a dry weight basis, it contains 25 - 35 percent protein, 10 - 15 percent minerals and 7 - 10 percent of amino acids, bio-active substances and bio-polymers. The carbohydrate and fat content of azolla is very low. Its nutrient composition makes it a highly efficient and effective feed for livestock (see Table 1). Livestock easily digest it, owing to its high protein and low lignin content, and they quickly grow accustomed to it. Moreover it is easy and economic to grow.
The Natural Resources Development Project (NARDEP), Vivekananda Kendra, carried out trials in Tamil Nadu and Kerala using azolla as a feed substitute. The trials on dairy animals showed an overall increase of milk yield of about 15 percent when 1.5 - 2 kg of azolla per day was combined with regular feed. The increase in the quantity of the milk produced was higher than could be expected based on the nutrient content of azolla alone. Hence, it is assumed that it is not only the nutrients, but also other components, like carotinoids, bio-polymers, probiotics etc., that contribute to the overall increase in the production of milk. Feeding azolla to poultry improves the weight of broiler chickens and increases the egg production of layers. Azolla can also be fed to sheep, goats, pigs and rabbits. In China, cultivation of azolla along with paddy and fish is said to have increased the rice production by 20 percent and fish production by 30 percent.

Fodder is an important requirement for cattle. Even if the animals are fed with commercial feeds from the market, fresh green grass or dry straw is a must for them as fodder availability greatly reduces the expenditure on commercial feeds.
The success of a dairy plant depends largely on increasing milk production without escalation in feeding cost. Growing fodder grass is a good option. Another is Azolla cultivation.
Azolla is a floating fern which resembles algae. It is rich in proteins, amino acids, vitamins and minerals. Experiments conducted by the Vivekananda Kendra-Natural Resources Development Project (VK- NARDEP), Kanyakumari district, Tamil Nadu have proved that the quantity and
quality of milk yield of cattle went up when they were fed with Azolla.
With support from the Department of Biotechnology (DBT), the research team at the institute has developed a sustainable model for backyard Azolla cultivation.
