Abstract

Additif alimentaire pour animaux, comportant des extraits de thé, additif alimentaire pour animaux renfermant, à titre d'ingrédient actif, des fibres de feuilles de thé, et aliments pour animaux renfermant des additifs de ce type. Ces extraits de thé ont une efficacité remarquable dans la prévention et le traitement des diarrhées tant infectieuses que non infectieuses chez les animaux domestiques, les volailles et les animaux d'agrément. Par ailleurs, ils améliorent la qualité du lait brut, augmentent la production de lait et améliorent l'efficacité de l'élevage. Les fibres de feuilles de thé précitées permettent de favoriser la régulation des fonctions intestinales des animaux domestiques, de guérir les diarrhées, d'augmenter la production laitière, d'améliorer l'indice de consommation, et de désodoriser les excréments.
