The nutritive value of a set of 10 woody forage resources (Italian alder, ash, chestnut, field elm, hazel,lime, black locust, white mulberry, holm oak and vine) was investigated. Leaves were collected in summer2015. Protein and fibre concentrations, condensed tannin concentration, in vitro digestibility (enzymaticmethod), and dry matter (DM) and nitrogen in sacco effective ruminal degradability were determined.Results show a large variability between species: crude protein varied from 82 to 245 g kg‑1 DM, in vitrodigestibility from 47 to 84%, and effective nitrogen degradability from 18 to 78%. White mulberry isthe most interesting species but ash, alder, elm and lime also present sufficient in vitro digestibility andnitrogen characteristics to be included in the diet of ruminants. Black locust, vine and holm oak presenthigh levels of condensed tannins and low effective nitrogen degradability.
