Relationship between climatic factors and the diet selected by ruminants on Karoo veld (Short communication)

  • 1984
  • Issue: 4
  • Volume: 14
P.J.L. Zeeman & A.J. Fourie Page: 178 - 180

Diet selection and intake by cattle, goats and sheep was related to climatic factors by principal-component analysis. Digestibility of selected material and digestible organic matter intake per metabolic size (DOMI/kg W0.75) were significantly correlated to a principal component combining rainfall,…

Paraformaldehyde-treated bird-resistant sorghum grain as energy source in fattening diets for beef steers (Short communication)

  • 1984
  • Issue: 1
  • Volume: 14
J.P. Campher, H.H. Meissner, T. Shelby & N. Janse van Rensburg Page: 52 - 54

Three groups of nine steers each were fed fattening diets, containing either non bird-resistant (NBR), paraformaldehyde-treated bird-resistant (PBR) or bird-resistant (BR) sorghum grain as the energy source, for 105 days. The BR group performed consistently worse than both the NBR…
