Proteins varie in its amino acid composition and this one is never ideal or sufficient for the animal. That’s why the diets are, very often, supplemented by some synthetic amino acids. Two different cereals produced in Slovenia are tested here (wheat Rezka and barley Gotic) supplemented or not by one (Lys) or two (Lys+Met) amino acids to obtain a better utilisation in the view of a weight gain superior, and the decrease of the nitrogen excreted. The results obtained by nitrogen balance studies with laboratory rats, show that these two cereals have a CP, TD and BV inferior to in literature cited. The PER gives some very good values for the weight gain in the presence of synthetic amino acids (2,23 g/lg protein for wheat and 2,4 g/lg protein for barley against 1,75g and 1.7 g without supplementation). Moreover the excretion of nitrogen shows a real decrease (34,4% for wheat and 35,4% for barley) for both third groups in comparison with the control group.
