^aValues presented as the means ± SEM of percent of total fatty acids of 8–9 replicate pigs collected at 26–29 days of age. AGA CON n = 8, AGA HF n = 8, SGA CON n = 9, SGA HF n = 9. Bold values are significance.

^bSize, main effect of birth weight (i.e., AGA vs. SGA); Diet, main effect of dietary intervention (i.e., HF vs. CON); Size*Diet, interaction effect of birth weight, and dietary intervention.

AGA, appropriate for gestational age; SGA, small for gestational age; CON, control; HF, hydrolyzed fat; FAME, fatty acid methyl ester; DMA, dimethylacetal; TUFA, total unidentified fatty acids.
