Rumen acidosis is a problem in many production systems where readily fermentable concentrates are fed. Although acidosis is more common as a subclinical condition that can impair fibre digestion, numerous factors can precipitate the clinical disorder. The objective of the present study was to begin development of a model of acidosis using a rumen simulation technique (Rusitec) and continuous pH monitoring for subsequent evaluation of contributing factors. In the present report the effect of reduced buffer concentration, non-protein nitrogen (NPN) addition and method of NPN provision on pH and feed dry matter disappearance were examined.
