Duck productivity is largely determined by the optimization of bodily functions. The food consumed greatly determines the development of digestive organs and internal organs of livestock. Digestive organs that are well developed and function optimally will be very decisive in turning feed into meat and eggs. The aim of the study is to look at the role of chitosan and bran fermented on the weight percentage of digestive organs of ducks. The treatment is R0 (45% corn + 35% concentrate + 20% bran without fermentation), R1 (45% corn + 35% concentrate + 20% fermented bran), R2 (45% corn + 35% concentrate + 19.5% fermented bran + 0.5% chitosan) and R3 (45% corn + 35% concentrate + 17.5% fermented + 2.5% chitosan bran). The variable measured is the weight percentage of the digestive organs (gizzard, small intestine and pancreas) in ducks. Data was processed using SAS Windows 16. The results showed that the treatment was not significantly different from gizzard weight. The average weight of the small intestine and pancreas at the R1 treatment was significantly higher than the control at 31.85% and 29.16%. It is can be concluded that fermentation of bran and chitosan in duck ration activates the work of the digestive organs of ducks in the segment of the small intestine and pancreas.
