Incidence of abnormalities of external genitalia among ruminant animals marketed in Akure, Nigeria.

An investigation into the incidence of abnormalities of the external genitalia in male ruminants was carried out in three livestock markets in Akure metropolis. A total of 1,090 bulls, 1,002 rams and 1,028 bucks from these markets were examined for the frequency of abnormalities of the external genitalia. Abnormalities observed included cryptorchidism, testicular hypoplasia, orchitis, paraphimosis and genital wounds.
