Dietary influence on pH and volatile fatty acids concentrations and production rates in the rumen and distal fermentation chamber (DFC) was investigated in Norwegian reindeer (Rangifer t. tarandus) on South Georgia in summer (SG), and in northern Norway in late summer (NS) and winter (NW). Mean [standard deviation (s)] ruminal pH was similar in SG reindeer (6.46, s = 0.13) and NW reindeer (6.45, s = 0.19), but significantly different from NS reindeer (6.87, s = 0.08)(P 0.05). Mean DFC pH in SG reindeer (6.92, s
