¹T0 – control, with no addition of mannoprotein [six adult (three males and three females) and six elderly dogs (three males and three females)]; T400 – addition of 400 mg/kg mannoproteins [six adult (three males and three females) and six elderly dogs (three males and three females)]; T800 - addition of 800 mg/kg mannoproteins [six adult (three males and three females) and six elderly dogs (three males and three females)].
