Case 2:
Clinical History:
Five Hereford x Angus beef calves died at 6-8 weeks of
age with signs of respiratory distress and collapse. Another calf was
examined at 2 days of age because of mild scouring and depression. At
2 weeks of age, the calf became recumbent, developed respiratory distress
and died within 24 hours.
At necropsy, the lungs were diffusely congested and severely
oedematous. The heart was severely enlarged, with dilation of the left
ventricle. There was pronounced pallor of the left ventricular myocardium,
with focal subendocardial mineralisation.
This is a low power view of the left ventricular myocardium.
A large coronary artery is at the bottom of the field. Only a small
area of normal myocardium is recognisable, the remainder of the tissue
appearing hypercellular.
