Topigs Norsvin performed a study within the EU-project 3D’Omics, to find how the lysine content in feed relates with the different genetic potential for nitrogen efficiency. Animal groups with extreme high/low breeding values for nitrogen efficiency grew in a two-phase ad lib feeding program with high/medium/low levels of lysine.
The experiment showed that breeding for improved nitrogen efficiency will result in increased average daily gain at similar lysine intake and that the genetic potential for average daily gain might be higher than the commercial levels of dietary lysine will attain.
