  1. Fatty acid content of abdominal adipose tissue, represented as mol%. Values are means from N = 5 per diet and age group (7 d and 14 d). SEM values are the pooled SEM across groups; CO, corn oil; FO, fish oil. P-values are from ANOVA F-tests for main effects of diet, age and their interaction (diet × age). Labeled means are from post-hoc comparisons using LSM, calculated following a significant ANOVA F-test for diet × age interaction. Those in a row without a common letter differ; P < 0.05. Indices of enzyme activities were calculated from mol%, using the following equations: SCD (Stearoyl-CoA desaturase)-16 (16:1n-7/16:0); SCD-18 (18:1n-9/18:0); D6D (Delta-6 desaturase) (18:3n-6/18:2n-6); DNL (De novo lipogenesis) (16:0/18:2n-6); EL (Elongation) (18:0/16).
