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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
