  1. 1Data are presented are LS means.
  2. 2Standard error reported is largest of diet LS means.
  3. 3 P-values reported are of contrast I (Control vs Product + Oil) and contrast II (Product vs Oil).
  4. 4Body condition score = determined on a 5 point scale with 0.5 point increments by a single person (Coffey, [13]; Patience, [14]), with a score of 1 representing poor condition, 5 representing over-condition and 3 considered ideal.
  5. 5Average piglet gain = litter gain averaged for treatment replications and adjusted for number of live piglets at each measurement.
