The objective of this study was to compare carnitine and chromium on sow reproductive performance. In addition, a second objective was to determine if the responses to carnitine and chromium were additive. It was concluded that Supplementing gestation and lactation diets with added L-carnitine and chromium had minimal effects on
number of pigs born alive per litter; however, the improvement in farrowing rate observed during both
parities resulted in greater overall number of pigs born. These data suggest that improvements in reproductive
performance from the two nutrients may be additive. Additional research is needed to verify the biological mechanisms L-carnitine and chromium improve sow productivity.
