Pengaruh Karbohidrat Mudah Larut (Dedak Padi) sebagai Pakan Tambahan pada Kambing Pe terhadap Kecernaan Bahan Kering dan Nutrien dengan Metode Indikator Internal

Abstract

The research was aimed to know the effect of soluble carbohydrate (rice bran) as a feed supplement to etawah crossbreed goat to the dry matter and nutrient digestibility with internal indicator method. The research used a Completely Randomized Design (CRD) with four treatments and four replicates, and each replicate consists of one goat. The four treatments were treatment A (native grass), B (native grass + 75 g rice bran), C (native grass + 150 g rice bran) and D (native grass + 225 g rice bran). The native grass were given ad libitum twice times a day in the morning and in the afternoon, besides the rice bran were given once a day in the morning according to the treatments, and drinking water were given ad libitum. Variables observed were dry matter, organic matter, crude protein, crude fiber digestibility, pH and total protozoa of liquid rumen.Results of the research indicated that the dry matter digestibility, organic matter digestibility and total protozoa of liquid rumen were increase significantly (P<0.05) by the rice bran supplementation, as well as crude protein digestibility but statistically not significant different (P>0.05). Treatments C and D were decrease significantly (P<0.05) and treatment A was not significant different (P>0.05) to the crude fiber digestibility. Rice bran supplementation caused pH of liquid rumen was decrease but not significant different statistically (P>0.05). It can be concluded that rice bran increased the dry matter, organic mater, crude protein digestibility, and total protozoa of liquid rumen, but decreased the crude fiber digestibility and pH of liquid rumen
