Abstract excerpt

Dairy farming is one of the most widespread agricultural activities in Brazil. Neonatal diarrhea remains a major challenge, contributing significantly to economic and production losses in Brazilian dairy cattle herds. Picobirnavirus (PBV) has been suggested as a potential viral agent associated with calf diarrhea. This study aimed to detect PBV genogroup I (GI) RNA in fecal samples from calves in a closed...
