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…
