Neonatal calve Colisepticemia: Bacteriological and Pathological Findings

A-3-days old calf, freshly dead, with a history of sudden deaths among neonate calves in the farm, was referred to the pathology and diagnosis department at the Veterinary Research Institute. Postmortem examination revealed a diffuse redding of the carcass particularly of the lungs, liver and intestine. Histopathologically thickening of alveolar septa by mononuclear cells, fibrinous thrombi and effusion of fibrinous exudates into alveoli were observed in the lung. Intestine showed complete loss of lining epithelium. In the liver there were loss of lobulation, fatty change and fibrinous thrombi. Bacteriologically, Pure culture of Eshericia coli was isolated from lung, liver and intestine using different methods. All findings confirmed the diagnosis of colisepticemia.

A STUDY OF LACTATION CURVES OF IMPORTED FRESIAN CATTLE IN A TROPICAL ENVIRONMENT

In 586 .iortrial laciabons of 150 Friesian cattle maintained at the National Veterinary' Research institute, Vom, from 1968 to 1983. Maximum milk production ,was attained in the fifth week of lactation. The fourth and sixth lactation curves showed superiority over the first, second, third and fifth. The curves apparently indicate that culling of unproductive animals before the 6th lactation could be economically unreasonable.
