Aspergillosis in racing pigeons is caused by the fungus Aspergillus fumigatus, which spreads through airborne spores. It primarily affects the respiratory system, leading to breathing difficulties, lethargy, and sometimes green-colored droppings. Antifungal Medication: There is no universally recommended treatment, but antifungal drugs like itraconazole or amphotericin B may be used in severe cases. #pigeonsport #pigeonhealth | Pigeon Kuif
