AbstractTheÂ Â aimÂ Â ofÂ Â thisÂ Â researchÂ Â wasÂ Â toÂ Â examineÂ Â theÂ Â influenceÂ Â ofÂ Â several encapsulants Â in encapsulating citric Â acid Â used as acidifier Â on protein digestibilityÂ and Â metabolizableÂ Â energyÂ Â in broilers.Â Â The Â materialsÂ Â used Â in Â this Â researchÂ Â were Â 20 broilersÂ Â of Â 21 Â daysÂ Â of Â age,Â Â liquidÂ Â citricÂ Â acid Â and Â encapsulatedÂ Â citricÂ Â acids.Â Â The encapsulantsÂ Â Â Â usedÂ Â wereÂ Â maltodextrin,Â Â Â Â lactoglobulinÂ Â Â Â andÂ Â zeolite.Â Â Â BroilersÂ Â Â were randomlyÂ Â allottedÂ Â to fiveÂ Â dietaryÂ Â treatmentsÂ Â with Â 4 replicationÂ Â Â each.Â Â The Â variables observedÂ Â Â Â wereÂ Â Â crudeÂ Â proteinÂ Â Â digestibilityÂ Â (DCPmanureÂ Â Â andÂ Â Â DCP/aecaiJ.Â Â Â apparent metabolizableÂ Â energy Â (AME) and Â apparent Â metabolizableÂ Â energy Â corrected Â N Â (AMEn). Data Â were Â analyzedÂ Â by using Â CompletelyÂ Â RandomizedÂ Â Design.Â Â The differenceÂ Â among the treatmentsÂ Â was further Â tested Â by using Duncan Â MultipleÂ Â RangeÂ Â Test. Â The result of this Â researchÂ Â showedÂ Â thatÂ Â whileÂ Â citric Â acid Â encapsulatedÂ Â Â withÂ Â maltodextrineÂ Â gave significantlyÂ Â Â differentÂ Â Â effectÂ Â (P<0.05)Â Â Â andÂ Â theÂ Â highestÂ Â crudeÂ Â proteinÂ Â Â digestibility (DCPmanurd.Â Â citric Â acid Â encapsulatedÂ Â with Â either Â lactoglobulinÂ Â and Â and Â maltodextrine gave Â significantly Â highestÂ Â results Â on Â digestibilityÂ Â (DCP1aecaiJ Â (P<0.05)Â Â Â and Â AME Â and AMEnÂ Â (P<0,01).Â Â Â Â It Â canÂ Â beÂ Â concludedÂ Â thatÂ Â maltodextrinÂ Â Â wasÂ Â theÂ Â bestÂ Â choiceÂ Â of encapsulant for Â citric Â acid Â based Â on the highest proteinÂ Â digestibilityÂ Â and Â metabolizable energy (JIIPB Â 2009 Vol Â 19 No 1: 1-9).Â Key Â wordsÂ Â :Â Â Citric Â Acid, Â Encapsulation,Â Â Â Protein Â Digestibility,Â Â Â MetabolizableÂ Â Â Energy, Broiler
