The study aims to determine and obtain the level of administration of fermented shrimp waste extract on the metabolizable energy value and nitrogen retention in laying hens of the production phase. The method used was experimental with complete randomized design and the effect of treatment using fingerprints with the Dunnet test. The treatment consists of five kinds with four repetitions, namely R0, the ration does not contain fermented shrimp waste extract; R1, ration contains 0.5% fermented shrimp waste extract; R2, ration contains 1% fermented shrimp waste extract; R3, the ration contains 1.5% fermented shrimp waste extract; R4, ration contains 2% fermented shrimp waste extract. The results showed that the addition of fermented shrimp waste extract as much as 1.5% resulted in the highest metabolizable energy value, and the addition of 1% resulted in the highest nitrogen retention value.
