Conclusions
Feeding lactation dietary lysine levels above NRC (1998) recommendations did not improve sow or litter performance. When synthetic lysine was added to sow lactation diets at 0.15%, there were no detrimental effects on sow performance. The decreased PUN concentrations when synthetic lysine was fed suggest that amino acids were used more efficiently. Feeding dextrose at 10% of the lactation diet may increase sow feed intake, particularly first parity sows.
