Abstract
Immunisation of entire males against gonadotrophin releasing hormone (GnRH) is effective in eliminating boar taint, however, it may be associated with an increase in backfat and reduced feed conversion compared with the production of entire males. In order to minimise these negative effects, it is important that the level of amino acids in diets fed to immunised males are appropriate (Dunshea, 2009). However, there is no published work on the lysine requirements of immunised males. The hypothesis of this experiment was that male pigs immunised against GnRH will respond differently to increasing levels of available lysine per MJ digestible energy (Av Lys/MJ DE) than entire male pigs.
