  • Scanning electron microscopy of the mucosal surface of the forestomachs and abomasa of grey, white and black Karakul lambs 
    Groenewald, Hermanus B.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute., 1992)
    Homozygous grey and white Karakul lambs suffer from a lethal genetic factor causing death after weaning. Previous studies revealed large milk-filled rumens in the grey and white lambs which was attributed to a significant ...
  • Sperm-storage tubules in the vagina of the ostrich (Struthio camelus)

  • Thoracic limb morphology of the red panda (Ailurus fulgens) evidenced by osteology and radiography 
    Makungu, Modesta; Groenewald, Hermanus B.; Du Plessis, Wencke M.; Barrows, Michelle; Koeppel, Katja Natalie (AOSIS OpenJournals, 2015-07-15)
    The red panda (Ailurus fulgens) is distributed primarily in the Himalayas and southern China. It is classified as a vulnerable species by the International Union for Conservation of Nature. The aim of this study was to ...
  • Thoracic limb morphology of the ring-tailed lemur (Lemur catta) evidenced by gross osteology and radiography 
    Makungu, Modesta; Groenewald, Hermanus B.; Du Plessis, Wencke M.; Barrows, Michelle; Koeppel, Katja Natalie (Wiley, 2015-08)
    There is limited information available on the morphology of the thoracic limb of the ringtailed lemur (Lemur catta). This study describes the morphology of the thoracic limb of captive ring-tailed lemurs evidenced by ...
  • Ultrasonographic abdominal anatomy of healthy captive caracals (Caracal caracal) 
    Makungu, Modesta; Du Plessis, Wencke M.; Barrows, Michelle; Koeppel, Katja Natalie; Groenewald, Hermanus B. (American Association of Zoo Veterians, 2012)

  • Ultrastructure of the epithelium of the rumen, reticulum and omasum of grey, white and black Karakul lambs 
    Groenewald, Hermanus B.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
    Mortalities due to digestive disturbances occur in homozygous grey and white lambs after they have reached weaning age. Milk-filled, distended rumens, due to malfunctioning of the oesophageal groove, are found 24 h after ...
  • Ultrastructure of the myenteric ganglia in the rumen, reticulum, omasum and abomasum of grey, white and black Karakul lambs 
    Groenewald, Hermanus B.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1993)
    Homozygous grey and white Karakul lambs die after they have reached weaning age. This is due to a lethal gene causing digestive disturbances. Previous studies revealed that grey and white lambs have large, milk-filled ...
