Abstract

Inhibition hydrolysis of carbohydrate by mulberry leaves extractABSTRACT. Mulberry leaves has a great potential as animal feeds because of its high nutrient content, but has deoxynojirimycin (DNJ) active matter. It is potential to inhibit carbohydrate hydrolysis process, come to monosaccharides. The objective of this experiment is to study the inhibiting ability of mulberry leave extract in carbohydrate hydrolysis process. The kinds of carbohydrates were using glucose, maltose, sucrose and starch. This experiment used twenty four of 60 days old male mice (Mus musculus). Diet and water were given ad libitum. Treatment were allocated ina factorial completely randomized design with three replications and two factors containing of completely mulberry leaves extract and variance of carbohydrates. Variable observed were feed consumtion, feed digestibility, body weight gain and blood glucose. The data were analyzed with univariate analysis of variance. The result showed that inclusion of mulberry leaves extract had decrease body weight (P 0,05) and reduce blood glucose (P 0,05).

Abstract

ABSTRAK Kandungan nutien dan produksi daun murbei cukup tinggi sehingga berpotensi menjadi sumber pakan ternak. Namun, daun murbei mengandung senyawa aktif 1-deoxynojirimycin (DNJ), yang dapat menghambat hidrolisis disakarida menjadi monosakarida. Penghambatan tersebut dapat meningkatkan fermentabilitas pakan berserat dalam system rumen. Tujuan penelitian ini adalah untuk mengkaji dampak senyawa DNJ yang terkandung dalam ekstrak daun murbei (EDM) dalam sistem pasca rumen. Penelitian menggunakan mencit sebagai hewan model percernaan pasca rumen. Penelitian terdiri atas 6 perlakuan dan 4 ulangan. Perlakuan terdiri atas: P0 = Ransum semi purified (kontrol), P1 = P0 + padatan residu fermentasi in vitro, P2 = P1 + EDM dengan kadar DNJ ransum sebesar 0,03%, P3 = P1 + padatan residu fermentasi in vitro yang diberi substrat EDM dengan kadar DNJ ransum sebesar 0,03%, P4 = P1 + EDM dengan kadar DNJ ransum sebesar 0,06%, dan P5 = P1 + padatan residu fermentasi in vitro yang diberi substrat EDM dengan kadar DNJ ransum sebesar 0,06%. Hasil penelitian menginformasikan bahwa penambahan ekstrak daun murbei dalam pakan mengakibatkan penurunan bobot badan, konsumsi dan kecernaan pakan serta kadar glukosa darah mencit. EDM tidak terdegradsi sempurna dalam sistem rumen, sehingga masih berdampak negatif pada sistem pasca rumen. Namun, fermentasi EDM dapat mengurangi dampak negatif senyawa DNJ dalam sistem pasca rumen.Kata kunci: Ekstrak daun murbei, 1-deoxynojirimycin, residu fermentasi in vitro, mencit.
