Animals were allocated into two groups (Control and Urtica) and fed concentrate and barley straw ad libitum. From day 23 to 29 a digestibility trial was conducted using 4 lambs per group. Lambs were slaughtered when they reached 25 kg. Concentrate and dry matter intake tended to be greater for Urtica lambs (P<0.10). Dry matter, fibre and protein apparent digestibility, growth rate and feed to gain ratio did not change (P>0.10) among experimental groups. On the other hand, carcasses from lambs fed the Urtica concentrate were heavier (P<0.05), although killing-out percentage was not affected (P>0.10).
