¹Data are presented are LS means.
²Standard error reported is largest of diet LS means.
³ P-values reported are of contrast I (Control vs Product + Oil) and contrast II (Product vs Oil).
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.
⁵Average piglet gain = litter gain averaged for treatment replications and adjusted for number of live piglets at each measurement.
