Digestibility and Nutritional Value of Fermented Straw Supplemented with Green Concentrate as Feed Ingredients for Holstein Friesian Dairy Cattle

The purpose of this study was to determine the effect fermented straw supplementation with green concentrate on nutrient content and digestibility. Green used as treatment white lead tree leaf flour ( Leucaena leucocephala ), Gamal meal Gliricidia sepium Indigofera meal. Proximate analysis carried out rice straw, 70% + 30% lamtoro (FRS tree), ) ). livestock for digestibility test 12 Friesian Holstein dairy cows. A randomized block design results showed that in able increase crude protein, fat, BETN decrease fiber. Crude protein did not differ three types concentrates. fat FRS higher than .
