Table 4 Feed and tocopherol intake and body weight of dams fed either a control or a CLA-supplemented dietd

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

  1. a-cMeans with superscripts without a common letter differ at P < 0.05. dValues are means, n = 12–14. Means with superscripts without a common letter differ at P < 0.05. Weeks 1–3: pregnancy, weeks 4–5: lactation; weight for week 3 is after delivery; tr., treatment. Data were analysed by two-way ANOVA with treatment, time and their interaction as fixed effects and animal as random effect
  2. esum of active α, δ- and γ-tocopherol considering conversion factors of 0.10 for γ-tocopherol and 0.03 for δ-tocopherol as compared to α-tocopherol (100 % active) [17]
