The aim of the present work was to determine nutrients and energy utilization of four hulless oat varieties, namely Paul (PA), Gehl “VAO-02” (GV), AC-Gwen (AC) and Lee Williams (LW) in growing pigs. The crude protein, lysine, crude fat and neutral detergent fibre contents (g kg-1 DM) ranged from 153 for LW to 184 for PA, 7.08 for LW to 7.94 for PA, 53.8 for LW to 72.1 for GV and 77.3 for PA to 120 for LW, respectively. Apparent ileal lysine digestibility differed (P<0.05) among the varieties and ranged from 60.0% for LW to 78.9% for AC. The DE and ME contents (MJ kg-1) also differed (P<0.05) among the varieties and ranged from 16.66 for LW to 17.92 for PA and 16.65 for LW to 17.90 for PA, respectively. Ileal amino acids digestibility and energy contents revealed variability among the varieties studied.
