Effect of roasting on ruminal degradation, intestinal digestibility and absorbable amino acid profile of cottonseed and soybean

  • 1995
  • Issue: 4
  • Volume: 25
G.E. Schroeder, L.J. Erasmus, K-J. Leeuw and H.H. Meissner Page: 109 - 117

The effect of heat processing on ruminal degradation, intestinal digestibility (UDP-D) and absorbable amino acid (AA) profile of cottonseed oilcake (CSOC) and soybean oilcake (SBOC) was calculated. CSOC and SBOC were roasted in a drum roaster at six temperature settings…

Effects of infused methionine, lysine and rumen-protected methionine derivatives on nitrogen retention and wool growth of Merino

  • 1995
  • Issue: 4
  • Volume: 25
J. Coetzee, P.J. de Wet and W.J. Burger Page: 87 - 94

Nitrogen (N) retention and wool growth rate (WGR) responses to various amino acids and derivatives as well as protein sources were determined with six ruminally and six abomasally fistulated Merino wethers in two balanced cross-over design experiments. The six treatments…
