ABSTRACT
Empty Fruit Bunches (EFB) are the by-product of the palm oil plantation industry. EFB has tremendous lignin content and low palatability. We aimed to assess the impact of EFB supplementation by the delignification process and in-vitro rumenal fermentation. The treatments were raw EFB (P0) and delignified EFB (P1). We evaluated rumen pH, total volatile fatty acids (VFA), ammonia concentration (NH3), dry matter digestibility (DMD), crude fiber digestibility (CFD), organic matter digestibility (OMD), methane gas production, fulvic acid content, and bacterial population. The results indicated that the treatment did not have a significant effect on DMD, OMD, pH, NH3 concentration, methane gas, and bacterial populations. Treatment showed a significant result (P<0.05) on total VFA. The contents of fulvic acid in raw and delignified EFB, both unfermented and fermented using rumen fluid in-vitro, were around 6.12-6.46%. The use of delignified EFB can accelerate rumen fermentation and increase VFA production.
