Extract

Acute (clinical) and subclinical rumen acidosis is a problem in many production systems where readily fermentable concentrates are fed. In previous experiments (Haubi et al., 2001) a model for subclinical acidosis using the Rusitec was presented. The objective of the present study was to establish a model for clinical acidosis, where excessive carbohydrate fermentation drops rumen pH below 5.0. The effects of N source on pH and feed dry matter degradation (DMD) before and after an acute case of acidosis were determined by comparing level of diet N and source (non-protein nitrogen [NPN] versus soya protein).
