Forage quality of leaf fodder from the main woody species in Iceland and its potential use for livestock in the past and present

Woody species played, and in many Nordic regions still play, a very important role in livestock feeding. However, forage quality (contents of macroelements and fibre fractions) of the leaves of common woody species is often inadequate. The aim of our study was to determine forage quality of leaves o...
