Multinutritional blocks were made from molasses, poultry litter, lime and minerals with two levels of urea: 5 and 10%. They were fed to groups each of 4 african hair sheep (20-25 kg initial weight) receiving cut grass (Panicum maximum) of low nutritive value; a control group received only the cut grass. The trial lasted 77 days. Block intake was higher (470 vs 375 g/animal/d) as was liveweight gain (65 vs 32 g/d) for the lower level of urea. The control group lost 32 g/d.
