Methane emissions are lower from reindeer fed lichens compared to a concentrate feed
Methane emissions from reindeer (Rangifer tarandus tarandus) fed lichens (mainly Cladonia stellaris) and a concentrate feed were determined using open-circuit respirometry. The lichen diet was low in crude protein ( 4 weeks prior to experiments and methane emissions recorded for two separate 23 h pe...

Methane emissions from reindeer (Rangifer tarandus tarandus) fed lichens (mainly Cladonia stellaris) and a concentrate feed were determined using open-circuit respirometry. The lichen diet was low in crude protein ( 4 weeks prior to experiments and methane emissions recorded for two separate 23 h periods for each diet. Methane emissions increased on average by 0.93 g/h (or by 5.8 times) in the first hour after feeding the concentrate feed, while emissions remained unchanged after the intake of lichens.
