The study aims to test the effect of the incorporation of certain cereals and protein in the diet on production performance of broilers. The growth test allowed the comparison of five almost iso -nutritional diets : a control diet soy, and four food with fava beans , peas for protein and barley, triticale cereals . Growth performance obtained with foods based peas are significantly degraded in terms of weight gain. This seems to be explained by the presence of anti- nutrients that are found in the raw material . sub consumption is recorded on the overall period. The presence of tannin in the variety could be a hypothesis to explain this under-consumption . This study confirms that faba bean can partially replace soybean meal up to 15% without affecting animal performance. Triticale and barley could be substituted by excellence corn up to 32 %.
