  • Changes in sheep oesophageal diameter and function during Geigeria ornativa (vermeerbos) poisoning and subsequent recovery 
    Snyman, Leendert D.; Carstens, Ann; Schultz, R.A. (Rowena Anitra); Joubert, J.P.J.; Labuschagne, Leonie (South African Veterinary Association, 2008)
    Changes in the oesophageal diameter and function together with changes in body weight, feed intake and the cardiac pulmonary flow index were investigated during experimentally induced poisoning with Geigeria ornativa and ...
  • Conditioned feed aversion as a means to prevent tulp (Homeria pallida) poisoning in cattle 
    Snyman, Leendert D.; Schultz, R.A. (Rowena Anitra); Joubert, J.P.J.; Basson, Karin M.; Labuschagne, Leonie; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2003)
    Conditioned feed aversion was investigated as a means to prevent tulp (Homeria pallida) poisoning in cattle on tulp-infested grazing. Aversion treatment with a combination of epoxyscillirosidin and lithium chloride together ...
  • Evaluation of activated charcoal as treatment for Yellow tulp (Moraea pallida) poisoning in cattle 
    Snyman, Leendert D.; Schultz, R.A. (Rowena Anitra); Botha, C.J. (Christoffel Jacobus); Labuschagne, Leonie; Joubert, J.P.J. (South African Veterinary Association, 2009-12)
    The efficacy of activated charcoal as a treatment for cattle (n = 57) poisoned by Yellow tulp (Moraea pallida) was investigated. Treatment with activated charcoal resulted in full recovery, irrespective of the degree of ...
  • Experimental evidence that the active principle of the poisonous plant Thesium lineatum L.f. (Santalaceae) is a bufadienolide 
    Anderson, L.A.P.; Joubert, J.P.J.; Kellerman, T. Stephanus; Pienaar, Barendina J.; Schultz, R.A. (Rowena Anitra); Bigalke, R.D. (Published by the Government Printer, Pretoria., 1987)
    The toxicity of Thesium lineatum is confirmed in sheep. A toxic crystalline bufadienolide, with the suggested trivial name thesiuside, has been isolated from it. This is the first cardiac glycoside to be isolated from ...
  • The experimental production of krimpsiekte in sheep with Tylecodon grandiflorus (Burm.f.) Toelken and some of its bufadienolides. 
    Prozesky, Leon; Anderson, L.A.P.; Joubert, J.P.J.; Kellerman, T. Stephanus; Schultz, R.A. (Rowena Anitra); Procos, J.; Olivier, Philippa M.; Bigalke, R.D. (Published by The Government Printer, Pretoria, 1983)
    Six bufadienolides were isolated from Tylecodon grandiflorus (Burm. f.) Toelken. The paretic syndrome, krimpsiekte, could be induced in sheep either by repeated oral administration of small quantities of plant material or ...
  • "Grootlamsiekte", a specific syndrome of prolonged gestation in sheep : further investigations 
    Basson, P.A.; Lucks, H.J.; Joubert, J.P.J.; Burger, J.H.S.; De Kock, V.E.; De Lange, M.; Bigalke, R.D.; Howell, P.G.; Reinecke, R.K.; Walker, Jane B. (Published by the Government Printer, Pretoria, 1972)
    By feeding both leaves and twigs of Salsola tuberculata var. tomentosa to pregnant ewes, it was established that the daily ingestion of 0,9 kg of this material for at least 10 to 50 days during any stage of gestation could ...
  • Krimpsiekte and acute cardiac glycoside poisoning in sheep caused by bufadienolides from the plant Kalanchoe lanceolata Forsk 
    Prozesky, Leon; Anderson, L.A.P.; Schultz, R.A. (Rowena Anitra); Joubert, J.P.J.; Kellerman, T. Stephanus; Erasmus, G.L.; Procos, J.; Bigalke, R.D. (Published by The Government Printer, Pretoria, 1983)
    Three toxic bufadienolides, one characterized as hellibrigenin 3-acetate, have been isolated from Kalanchoe lanceolata Forsk. Typical signs of cardiac glycoside poisoning, involving the gastro-intestinal, neuromuscular ...
  • An ovine hepatotoxicosis caused by the plant Hertia pallens (DC.) Kuntze (Asteraceae) 
    Prozesky, Leon; Kellerman, T. Stephanus; Jordaan, P.; Welman, Wilhelmina G.; Joubert, J.P.J.; Bigalke, R.D. (Published by The Government Printer, Pretoria, 1985)
    A field outbreak of Hertia pallens poisoning in sheep is described. The hepatotoxicity of the plant was experimentally demonstrated in 7 sheep which developed lesions that ranged from a diffuse degeneration to centrilobular ...
  • Paralysis in lambs caused by overdosing with parbendazole
