MULTIPLE ORGAN AGENESIS AND JAW BAD FORMATION IN NEWBORN DAIRY CATTLE: CASE REPORT

Abstract

Congenital anomalies are abnormalities in structures and functions present during gestation or after birth, and are often the result of environmental or genetic factors, or both. Their etiology may also be associated with infectious agents, such as viruses, hereditary characteristics, ingestion of toxic plants, or exposure to chemical agents. Congenital anomalies are rare, occurring sporadically, but they can also occur in the form of outbreaks. A Dutch calf arrived at the Veterinary Clinic of the Pontifical Catholic University of Paraná (PUCPR), in Toledo, PR, at three days of age, initially presenting with malformation of the jaw and atrophy of the limbs. Clinical observations indicated diarrhea and dehydration caused by the malformation of the jaw, which obstructed its food intake. Due to the clinical condition of the animal, euthanasia was decided. The necropsy also revealed agenesis of the entire urinary tract and partial agenesis of the reproductive tract, where the animal had only a vulva and vagina. The reported case is a congenital malformation of sporadic occurrence, characterized by multiple deformations and associated with undetermined genetic factors.
