    Four cases of uterine coccidiosis showing readily-detectable macroscopic lesions were collected over a period of two years during which 451 female impalas [Aepyceros melampus (Lichtenstein, 1812)] were examined post ...
  • The influence of magnesium sulphate on the absorption, excretion and retention of calcium and phosphorus by sheep fed on phosphate supplemented rations 
    Myburgh, S.J.; DuToit, ]. de V.; South Africa. Dept. of Agricultural Technical Services; Tustin, R.C.; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E. (Pretoria : Government Printer, 1970)
    Evidence is put [orward showing that continuous excessive intakes of magnesium sulphate by sheep, for example in dnnking water, may result in losses of calcium from the body. However, when the intakes of both these ...
  • The antigenicity of Clostridium botulinum type C toxin administered per os

    Large quantities of toxoid given to rabbits per os did not elicit a primary immune response. Toxin absorbed through the intestinal wall of guinea-pigs and toxoided produced an anamnestic response on injection into ...
  • Immune response to dead and live Eschericia coli vaccines and colostral transfer of immunity to calves and lambs 
    Cameron, Colin McKenzie; Fuls, W.J.P.; South Africa. Dept. of Agricultural Technical Services; Tustin, R.C.; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E. (Pretoria : Government Printer, 1970)
    Administration of a single injection of killed polyvalent Escherichia coli (Migula, 1895) vaccine to ewes and cows resulted in a marked increase in the mouse protective properties of their sera. Antibodies were effectively ...
  • Changes in the levels of plasma electrolytes and glucose in severe artificially induced acidosis in Merino sheep 
    Procos, J.; Schubert, Annette; Briel, B.J.; South Africa. Dept. of Agricultural Technical Services; Tustin, R.C.; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E. (Pretoria: Government Printer, 1970)
    Severe acidosis was induced in wethers by the infusion of mineral and organic acids. No clinical signs apart from slight panting, were observed despite a fall in plasma glucose levels which occurred either spontaneously ...
  • Studies on the transmission of African horsesickness 
    Wetzell, H.; Nevell, E.M.; Erasmus, B.J.; South Africa. Dept. of Agricultural Technical Services; Tustin, R.C.; De Lange, M.; Reinecke, R.K.; Walker, Jane B.; De Kock, V.E. (Pretoria: Government Printer, 1970)
    Laboratory-reared Aedes aegypti (Linnaeus, 1762), Culex pipiens fatigans Wiedemann, 1828, and trap-caught Culicoides biting midges were fed on African horsesickness (AHS) virus solutions and on horses infected with AHS. ...
  • Experimental diamidine poisoning due to commonly used babecides
