Effect of adding fermented shrimp waste extract in ration on metabolizable energy and nitrogen retention in laying hens

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