Abstract
Azolla easily grown in wild environment and even can be growth under controlled environment like polyhouse and green house. Azolla is treated as a feed supplement to poultry birds. Two species of azolla viz., A. microphylla and A. filiculoides are analysed for their nutritional parameters so as to select the suitable Azolla species to feed the poultry birds. The total protein content of the eggs laid by the Azolla fed birds was high (14.0 g/100g of edible portion) and the total carotene content of these eggs (440 µg/ 100 g of edible portion). The increase in egg productivity, nutritional value and savings in the concentrated feed clearly indicated the suitability of Azolla as a potential feed supplement for poultry birds.
