The lysine intake, first-pass, and systemic use of lysine by the PDV in piglets receiving either an HP or an LP diet

Diet	Lysine intake, μmol/kg per h	Arterial use, μmol/kg per h	First-pass use, μmol/kg per h	Recycling, μmol/kg per h	Total lysine use, μmol/kg per h
HP	518	230  ± 40	−15  ± 63	2  ± 59*	213  ± 32
LP	207	126  ± 25†	91  ± 36§	31  ± 27*	186  ± 29

Values shown are means ± SEM. 

^*No significant difference from zero. 

^†Significant difference between HP- and LP-fed piglets at P < 0.05. 

^‡Significant difference between HP- and LP-fed piglets at P < 0.001.
