Effect of diets differing in rumen soluble nitrogen on utilization of poor-quality roughage by sheep

  • 2015
  • Issue: 5
  • Volume: 45
A.M. Mentz, W.A. van Niekerk, A. Hassen, R.J. Coertze & B.S.Gemeda Page: 528 - 537

This study investigated the effects of replacing rapid-release nitrogen (N) from urea with a graded level of slow-release N (Optigen® II) source on intake, digestibility, rumen fermentation and microbial protein synthesis, when sheep were fed a poor-quality roughage diet. Five…

In vitro degradation of melamine by ruminal microorganisms

  • 2015
  • Issue: 2
  • Volume: 45
C.W. Cruywagen & T. Calitz Page: 137 - 142

An in vitro study was conducted to determine the extent of melamine degradation in rumen liquor. Rumen liquor was collected from two ruminally cannulated Holstein cows on four separate dates, one week apart. Erlenmeyer flasks (250 mL) were prepared for…
