Digestibility of Plants in Ruminal Fluids of Barren-Ground Caribou,
Arctic,
34(4): 321-324
The comparative digestibilities of plants and their rates of digestion in vitro were assessed by fermentation with ruminal
fluids obtained from barren-ground caribou (Rungifer rurundus groenlundicus) shot on their winter range in the southern Northwest
Territories. There was a near-linear increase in the in vitro, dry-matter disappearance (IVDMD) with fermentation time (30-120 h) for all
eight lichens pecies that we tested. In contrast, IVDMD was essentially maximal after 60 h fermentation for …
