	abstract = {Five two-tooth Coopworth ewes were used to monitor the effects  of changing caecal pH on magnesium (Mg) solubility and absorption pH  change was induced by infusion of volatile fatty acid (VFA) (0, 220,  440, 660, 880 mmol; ration 0.80:0.15:0.05 acetic:propionic:butyric in  2016 ml of deionised water) into the terminal ileum for 24 h.  Treatments were randomly applied to each animal using a latin square  design. During the infusion samples of blood and urine were taken at 4  h intervals and proximal colonic digesta at 4, 16 and 24 h. Apparent Mg  absorption from the large intestine was estimated from changes in plasma  Mg concentration and urinary Mg excretion. Sixteen hours after the  commencement of infusion digesta pH decreased and Mg solubility  increased. For example, with the 880 mmol infusion digesta pH had  decreased by 2.1 },
