There is an increasing interest in exploring the rumen ecology of tropical ruminants for two reasons: increase the utilization of lignocellulolytic feed materials for better productivity and the search for novel, beneficial microbial species that may reside in the rumen of tropical ruminants fed low quality roughage. There is still a paucity of knowledge on rumen ecology with regards microbial interactions, consortium formation synergism and cross feeding. While the theoretical basis for optimum nutrition of tropical ruminants has been widely accepted, the approaches wherein the rumen microorganisms can be manipulated to further improve rumen fermentation have not yet been fully understood and utilized. This is due the high complexity of the rumen ecology. Based on the research results reviewed and the limited local work done on native ruminants, it is concluded that there is a bright prospect in manipulating rumen ecology using natural feed resources.
