Enhancing the Utilization of Oil Palm (Elaeis Guineensis) Frond by Steam Treatment and Nitrogen Supplementation in Ruminants

The overall Objective of this study was to investigate the possibility of improving the feeding value of oil palm frond (OPF) by steaming-process Animal performance is a function of intake of digestible nutrients and the efficiency of their utilization From a review of literature, the potential i...

Steam treatment increased water solubility (P <0.00/) of OPF, resulting in a decrease in the neutral detergent fibre (NOF) fractions, particularly the hemicellulose and an increase in acid detergent lignin (ADL) content.
