Clinical and anatomical studies on the scrotal and pelvic genitalia of Sokoto Gudali bulls in Northern Nigeria.

The scrotal and pelvic genitalia from 2400 Sokoto Gudali bulls aged three to five years were studied clinically (by ante mortem palpation and measurement) and anatomically (by direct examination and measurement of the post mortem material). In general the difference between the mean clinical and anatomical measurements was not significant (at the 5 per cent level). Gross abnormalities observed included: testicular degeneration, 60 bulls (2.5 per cent); orchitis, 48 bulls (2.0 per cent); testicular hypoplasia, 35 bulls (1.45 per cent); epididymitis, 37 bulls (1.54 per cent); spermatic granuloma, two bulls (0.08 per cent); seminovesiculitis, 43 bulls (1.79 per cent); scrotal stryptortrichosis, 126 bulls (5.25 per cent). Lesions had no seasonal pattern and occurred randomly throughout the year.
