The effect of formaldehyde treatment of canola oilcake meal and sweet lupins on the in situ dry matter and crude protein digestibility

  • 2023
  • Issue: 1
  • Volume: 53
T.S. Brand, J.H.C van Zyl, O.Dreyer Page: 91 - 100

The value of feed protein sources in ruminant nutrition is measured by how effectively the protein is degraded in the rumen and converted into microbial protein. High-producing ruminants acquire high nutritional requirements to sustain their metabolic demands for production and…

Rumen microbial diversity of Bonsmara cattle using amplicon sequencing during a 120-day growth trial

  • 2022
  • Issue: 2
  • Volume: 52
D.A. Linde, E. van Marle-Köster, C.J.L. du Toit, M.M. Scholtz & D. Schokker Page: 148 - 161

Improved understanding of the microbial populations during intensive feeding of feedlot cattle holds potential for optimizing production efficiency. Ionophores are used to increase the production and efficiency of ruminants and are commonly used in South African feedlots. Bonsmara bull calves…

Aspects of the feeding ecology of a browsing ruminant: the kudu

  • 1983
  • Issue: 1
  • Volume: 13
N. Owen-Smith, S.M. Cooper & P.A. Novellie Page: 35 - 38

Forbs form the preferred dietary component of the kudu (Tragelaphus strepsiceros). This preference was associated with the high nutrient content of their leaves and less fibrous stem material relative to trees and shrubs. Woody browse was most sought after during…

An evaluation of the use of blood metabolite concentrations as indicators of nutritional status in free-ranging indigenous goats

  • 2000
  • Issue: 2
  • Volume: 30
R. Pambu-Gollah, P.B. Cronje and N.H. Casey Page: 115 - 120

The aim of this study was to determine whether blood metabolite concentrations in free-ranging indigenous goat are sensitive to expected variations in nutrient supply, and whether they could be used to evaluate different kidding season at two locations subject to…
