Background and Aim: This study was aimed to improve the quality of the eggs of Mojosari duck (Anas javanica) through complete feeding containing soybean husk was fermented using cellulolytic bacteria of Spodoptera litura.
Materials and Methods: This study consisted of three stages: The first stages, isolation and identification of cellulolytic bacteria from S. litura; the second stage, the fermentation of soybean husk through the application of bacterial cellulolytic isolate from the first stage; and the third stage, the application of the best complete feed formulation from the second stage to Mojosari duck.
Results: There are four dominant bacteria: Bacillus sp., Cellulomonas sp., Pseudomonas sp., and Cytophaga sp. Furthermore, the best reduction of the crude fiber of soybean husks is the use of Cellulomonas sp. bacteria. The final of the study, the quality of the eggs of Anas javanica, was improved, as indicated by cholesterol decrease from the yolk without the decrease of egg weight and eggshell thickness, although the decrease in egg yolk color was inevitable.
Conclusion: Soy husk fermentation using cellulolytic bacteria of S. litura was added to complete feeding can be performed to improve the quality of the eggs of Mojosari duck. Keywords: cellulolytic bacteria, eggs quality of duck, soybean husk fermentation, Spodoptera litura.
Keywords: cellulolytic bacteria, eggs quality of duck, soybean husk fermentation, Spodoptera litura.
