Feed intake, rumenal pH and lactic acid in reindeer during transition to a complete ration added buffer and fat
Feed intake, general condition, rumenal pH and lactic acid content was followed during feeding of starved reindeer on a coventional diet (RF-71). The result was a dramatic decrease of rumen pH (pH=5.1 in experiment no. Ill) a few hours after feeding of the coventional diet, but this could be counter...
