RESUMEN
Clinical cases of both Zn and Cu deficiencies are reported in a cattle farm in Kordofan Region of the Sudan after drought. The animals showed general weakness, stunted growth, infertility, parakeratosis and achromotrichia. There was macrocytic hypochromic anaemia and low Cu and Zn concentrations in sera. The condition was more prevalent in zebu-Friesian crosses than the local breeds. Drought and marginal or low Cu and Zn content in pasture may be the predisposing factors.

The clinical signs and lesions of Nubian goats and Desert sheep orally dosed with fresh and dry leaves and stems of Ipomoea carnea at 2.5, 5 and 10 g/kg/day were studied. The signs of Ipomoea poisoning were inappetence, depression, weakness of the hind limbs, dyspnea, staggering, and pallor of the visible mucous membranes. The main lesions were focal necrosis and fatty vacuolation of centrilobular hepatocytes, accumulation of fibroblasts in hepatic portal tracts, degeneration or necrosis of the cells of the renal proximal convoluted tubules, hemorrhage in renal cortices, in renal medullas and in cardiac muscle fibers, focal pulmonary edema, and emphysema and straw-colored fluid in serous cavities. Increased serum aspartate amino transferase and ammonia concentrations, and decreased concentrations of total protein, calcium and magnesium in the serum of Ipomoea-poisoned animals were detected. Hematological changes indicated the development of normocytic normochromic anaemia.

Sera of 740 camels of both sexes from three regions of Sudan were tested for antibodies to Brucella abortus. The overall incidence of antibodies was 4.9%. The highest positive number of samples (7.5%) was from the Eastern Region followed by Darfur Region (3.1%) and the Central Region (2.0%). Brucella antibodies were as frequent in males (5.6%) as females (4.5%).
