Abstract

L'invention porte sur des procédés visant à renforcer la palatabilité de compositions destinées à la consommation d'un animal, et ceci en ajoutant aux compositions une quantité d'oxyde de faire renforçant la palatabilité. L'oxyde de fer est ajouté dans une quantité comprise entre environ 0,0 1 % en poids de la composition sur une base de matières sèches, et généralement dans des quantité comprises entre environ 0,01 % et environ 0,25 % en poids de la composition. Les compositions contenant l'oxyde de fer sont ingérées plus fréquemment et à une vitesse supérieure par des animaux, notamment des animaux difficiles ou des animaux plus âgés qui ont tendance à ne pas manger suffisamment d'aliments leur permettant de se maintenir en bonne santé.
