Abstract

In a nearly two-year-old ram, descending from a breeding trial to investigate the effects of shortness of the lower jaw (brachygnathia inferior), a congenital cardiac anomaly was observed. At the age often months the affected animal, a cross breed of Cameroon Sheep and East Friesian Milk Sheep, showed exercise-induced respiratory distress for the first time. Auscultation revealed a loud systolic heart murmur (grade 5) on both sides of the thorax, most prominent over the left third intercostal space at shoulder height. Postmortem examination of the ram's heart showed a pentalogy of Fallot, consisting of a pulmonic stenosis, a ventricular septal defect, an overriding aorta, a right ventricular hypertrophy and a patent foramen ovale. A genetic defect has to be considered as a possible reason.
