Lysine requirements of modern genotype finisher pigs

摘要

Moore et al. (2013) determined the performance responses to dietary lysine concentrations of the modern genotype pig from 50 to 100 kg livcwcight (LW) and found that the lysine requirement to optimise growth performance in this weight range was higherby approximately 10% than that being used by the Australian industry. The aim of the current study was to confirm the optimal standardised ileal digestible lysine (SID Lys)/MJ digestible energy (DE) ratio for a modern genotype of entire male and femalepigs from 60 to 100 kg LW obtained in a research facility.
