Objectif: Le present travail a ete entrepris pour determiner l’influence de la substitution graduelle de tourteau de soja par la feverole sur la croissance et la conformation de la carcasse chez les poulets de chair. Methodologie et resultats: Notre essai a ete porte sur 50 poussins de souche ISA repartis en 05 lots homogenes et soumis a 05 regimes alimentaires differents par leurs taux d’incorporation de 0, 3, 6, 9 et 12 % de feverole. Les resultats obtenus ont revele que les sujets nourris aux regimes 0, 3, 6 et 9 % de feverole donnent des performances de croissance et de conformation de carcasse satisfaisantes par rapport aux sujets nourris au regime de 12 % de feverole . D’ou l’incorporation de la feverole devrait etre plafonnee a des taux inferieurs a 12% afin de reduire les charges en tourteau de soja dans les rations alimentaires de poulet de chair. Conclusion et application des resultats: Cet essai est un objet qui permet d’ameliorer les performances de croissance et de conformation de carcasse chez les poulets de chair. Elle montre que l’incorporation de la feverole a des taux inferieurs a 12 % reduit les charges en tourteau de soja dans les rations alimentaires de poulet de chair. Mots cles: Substitution, soja, feverole, performances zootechniques, poulet de chair English Abstract Objective: This work was undertaken to determine the influence of the gradual substitution of soybean meal on carcass growth and conformation in broiler chickens. Methods and results: Our test was carried out on 50 chicks of ISA strain distributed in 05 homogeneous batches and subjected to 05 different diets by their incorporation rates of 0, 3, 6, 9 and 12% of faba beans. The results obtained showed that subjects fed on diets 0, 3, 6 and 9% of faba bean gave satisfactory carcass growth and conformation performances compared to subjects fed on a 12% faba bean diet. Hence the incorporation of fababeans should be capped at rates below 12% in order to reduce soybean meal loads in broiler feed rations.  Conclusion and application of the results: This test is an object, which improves the performance of carcass growth and conformation in broiler chickens. It shows that incorporation of faba beans at rates below 12% reduces soybean meal loads in broiler feed rations. Keywords: Substitution, soybeans, faba beans, zootechnical performances, broiler chickens
