Table 5 Liver weights, liver TG content and FA composition of total liver lipids of dams fed either a control or a CLA-supplemented diet (g/100 g of total FA)a

From: Conjugated linoleic acid influences the metabolism of tocopherol in lactating rats but has little effect on tissue tocopherol concentrations in pups

  1. aValues are means at day 14 of lactation, n = 12–14. Data were analysed by one-way ANOVA with treatment as fixed effect and animal as random effect
  2. bto estimate desaturase activities, desaturase indices were calculated as product-to precursor ratios of individual fatty acids. Δ-9D 16, Δ-9 desaturase index for C16:1n9, Δ-9D 18, Δ-9 desaturase index for C18:1n9, Δ-6D n6, Δ-6 desaturase index for the n6 line
