Abstract

Several in vitro studies have indicated that the potential difference (p.d.) across the rumen wall is important for magnesium (Mg) absorption and that increases in p.d. as a result of high rumen potassium (K) concentration may reduce Mg transport. The aim of this work was to provide quantitative data on the relationship between p.d. and Mg absorption in the live animal and on diurnal variation in p.d. Twelve rumen cannulated ewes, weighing 45
