N2 - • Silvopastoral agroforestry – integratingshelterbelts, hedgerows or in-field trees withgrazing livestock – can provide domestic animalswith benefits, including shelter and shade, as wellas supplementing their diets as tree browse orfodder.• This study sampled leaves from three nativedeciduous tree species – willow, alder and oak –from three sites across the UK, and analysed theirmineral, energy and protein content.• Willow leaves from all sites were found to containhigher concentrations of zinc and cobalt thansheep requirements for these minerals. Seleniumconcentrations were found to be more dependenton the site than the tree species.• Metabolisable energy of leaves sampled wasgreatest in alder, while higher crude-proteincontent was associated with spring in all species.• More research is required to investigate the value ofdifferent tree species as a mineral supplement forruminant livestock, and to address how leaf feedcould be integrated into their diet.
