Abstract
The more a sow eats during pregnancy, the less she eats during lactation. Low voluntary feed intake (VFI) during lactation appears to be linked to the body fatness of the sow (Williams and Smits, 1991) and may be due to specific metabolic signals that limit VFI during lactation. The hypothesis for the following experiment was that the plasma concentrations of non-esterified fatty acids (NEFA), glycerol and insulin increase with body fatness, and that there is a negative relationship between VFI during lactation and the plasma concentrations of these metabolites.
