Mean (± S.E.) Percentage difference between time spent interacting with the objects in the Spontaneous Object Recognition Test (approximately 41 days). Sessions were separated by a 15-min retention time. Superscript letters indicate differences between the two sessions within one category of pigs (^a,bP < 0.05): a Different neonatal supplementation of the pigs (energy: coconut oil or commercial product; no energy: water or sham-dosed). Effects: supplementation: P = 0.788; session: P = 0.007; supplementation × session: P = 0.660. b Different levels of IUGR at birth (IUGR 1–3 = presence of 1–3 for the characteristics for IUGR). Effects: IUGR: P = 0.638; session: P = 0.007; IUGR × session: P = 0.042
