This research evaluates the phenotypic characteristics of male Peranakan Ongole (PO) cattle in Napis Village, Tambakrejo District, Bojonegoro Regency, East Java. The research method used is a case study through observation, photography, and direct measurement. The location and research sample were determined through purposive sampling based on the characteristics of cattle according to SNI 2020 PO cattle.
