The aim of this research are 1) to find out difference treatments of Azolla pinnata addition to the weight of male Mojosari ducks, and 2) the effective addition of Azolla pinnata . This research is experimental research using 5 treatments (without addition of Azolla pinnata , addition of Azolla pinnata 5%, 10%, 15% and 20%) with replication 5 times each repetition. Data collection was done by calculating body weight gain, Feed Consumption Rate (FCR) and analysis of business.  The result of this research is the addition of Azolla pinnata on ration influencing the increase of duck weight of male Mojosari and the addition of Azolla pinnata 20% most effective and can be applied for male Mojosari duck.
