摘要：Digestat sludge from layer chicken manure potentialy to be used as livestock feed aswell as fertilizer and biogas. This study aimed to determine the effect of feedingfermented sludge digestat in the form of dirt laying hens using Aspergillus niger as afermentor in broiler rations. This study using Completey Randomized Design withfour replications wich each repeat contains four chicken. This study used four levelstreatment of sludge digestat fermentation, namelycontrol or without fermenteddigestat slude, giving 2%, 4% and 6% of fermented digestat sludge. The resultsindicated that fermentation by A. niger increased crude protein content of sludgedigestats as much as 55.6% i.e. from 9.84% to 15.31%; while the provision of sludgedigestats fermented by A. niger through 6% had no effect on feed intake, conversionfeeding, body weight gain, feed cost per gain, slaughter weight, carcass percentagewhich include chest, back, wings and thighs, as well as non-carcass percentage whichinclude heart, gizzard, and liver. This study can be concluded that the sludge digestatfermented by A. niger can be used to substitute 6% of broiler chickens ration
