Although milk-fever (paresis puerperalis) is commonly thought to occur in cattle only, yet some cases have been descriptionbed in pigs (Ellenberger, Herz, Wöstendorf) and goats (Schmid, Giovanoli, Tobiassen), and still rarer cases have been observed in sheep (van Hoopen). On 11.7.33 I was called to the farm Orab, District Gibeon, S. W .A., to investigate the cause of the sudden death of 6 valuable karakul stud-ewes. On arrival I found three sheep dead and one animal sick. Keywords: Milk-fever, sheep.
