  • Defluorination of aqueous solutions of superphosphate for use in animal nutrition 
    Truter, G.J.; Louw, J.G.; Alexander, R.A.; Clark, R.; Louw, J.G.; De Kock, V.E. (Published by The Government Printer, Pretoria, 1952)
    A method of preparing low-fluorine water solutions of superphosphate as a source of phosphate for farm animals is described. It consists of the preparation of a concentrated solution, sedimentation of the insoluble ...
  • Digestibility of lucerne hay with special reference to experimental technique in digestion trials (second report) 
    Groenewald, J.W.; Myburgh, S.J.; Louw, J.G.; Alexander, R.A.; Clark, R.; Louw, J.G.; De Kock, V.E. (Published by The Government Printer, Pretoria, 1952)
    (1) In a continuation of the study of the digestibility of the same lucerne hay by the same steers at different times further evidence of a period influence on digestibility was obtained. This influence could be reduced ...
  • The effect of body stores and of method of supplementation on the efficiency of calcium and phosphorus utilization by sheep 
    Reinach, Norman; Louw, J.G.; Groenewald, J.W.; Alexander, R.A.; Clark, R.; Louw, J.G.; De Kock, V.E. (Published by The Government Printer, Pretoria, 1952)
    (1) The Ca and P metabolism of two groups of young sheep, depleted of these minerals, was investigated in a series of three balance studies. (2) During the first 10 days on the bone meal supplemented ration, the inorganic ...
  • The influence of processing on the efficiency of proteins 
    Myburgh, S.J.; Louw, J.G.; Groenewald, J.W.; Alexander, R.A.; Clark, R.; Louw, J.G.; De Kock, V.E. (Published by The Government Printer, Pretoria, 1952)
    Employing an improved nitrogen balance method the influence of mild heat treatment on the digestibility and biological value of a mixture of plant proteins has been determined. The heat treatment resulted in a small ...
  • The utilization of phosphorus from different sources by the rat 
    Reinach, Norman; Louw, J.G.; Alexander, R.A.; Clark, R.; Louw, J.G.; De Kock, V.E. (Published by The Government Printer, Pretoria, 1952)
    An experiment has been carried out in which the relative availability to young rats of the phosphorus in bone meal, bone ash, dicalcium phosphate and tricalcium phosphate has been ascertained. Live weight gains, the ash ...
