The main goal of feed analysis is to predict the productive response of animals, in this case ruminant production, when fed diets of a given nutrient composition. A systematic approach to the overall aspects of animal production is vital for a stable and profitable output. Ranking forages can benefit the local producers to value each type of forages they feed the animals. From this point of view, a database must be developed containing sufficient samples of feeds and forages with relevant data determined under relatively uniform conditions, although animal variation due to preference, physiological state or genetic potential for production may, on the other hand, contribute to errors in measurements of forage quality. Relative feed value (RFV) is the forage quality index used widely in the United States as an important tool in the marketing of forages. In Malaysia, however, this index has not been established for assessing the status of local grass quality and how it relates to the performance of the local ruminant industry. The objective of this paper is to estimate RFV of the local B. decumbens grass towards the future establishment of its index under tropical climate. RFV between 74-84 obtained from this study was calculated using CP and ME values from a 5-year proximate analysis data from the Department of Veterinary Services (DVS) of local B. decumbens, sampled from the southern region of Peninsular Malaysia. If this forage is produced on a large scale, this assessment can help the producers and farmers differentiate between lots that are more or less valuable, thus making it a useful marketing and decision-making tool.
