Living Animal Cases of congenital Porphyrinuria



SOME time ago, in a single herd of grade short-horn cattle, running with one bull, on a farm in Swaziland, five living of Congenital Porphyrinuria were discovered. From the account given by the farmer, there had been seven other cases in the herd. Only one bull (a pure-bred, roan shorthorn) had been used during this period, and on an adjoining farm where he had also been employed, one case had occurred with certainty. The bull himself is normal but his dam was said to have been an unthrifty animal ; possibly she, also, may have been a porphyrinuric.
