title: Prolapse of the phallus and cloaca in the ostrich (Struthio camelus).
abstract: The incidence of cloacal prolapse in ostrich chicks hatched and raised on the Oudtshoorn Experimental Farm during the 1992-1993 breeding season was investigated. The condition which occurred primarily in male chicks, affected 14.65% of the total number of chicks hatched. The mortality rate amongst chicks with cloacal prolapse was very high. Although the pathogenesis and aetiology of the condition is unknown, a species of Cryptosporidium was present in large numbers in affected cloacas. Treatment with systemic antibiotics was found to be effective in some cases.
