Table 2 Overview of the studies that investigated the effects of lipid supplementation on sow lactating performancea,b

From: Optimizing dietary lipid use to improve essential fatty acid status and reproductive performance of the modern lactating sow: a review

  1. aSummary of the results from 13 published studies from 1989 to 2012 that were not included in previous reviews [12, 13] and reported on supplemental dietary lipids in lactating sows diets
  2. bEstimated means represented by bars show the improvement of lipid supplementation relative to lactation diets containing no added lipids. Variables reported include: average daily energy intake (ADEI), sow body weight (BW) change, and litter daily gain
  3. cReferences are presented in chronological order
  4. dn refers to the number of observations per treatment and was used as the weighing factor to calculate the average of the response
  5. eLipid sources: choice white grease (CWG), animal-vegetable blend (A-V blend), and medium chain triglycerides (MCT)
  6. fWeighted averages were calculated to account for the different sample sizes in each of the studies
  7. *P < 0.05
