Table 2 Nutrient composition and fatty acid profiles of the herring oil, soya oil, and canola oil experimental diets

From: High feeding intensity increases the severity of fatty liver in the American mink (Neovison vison) with potential ameliorating role for long-chain n-3 polyunsaturated fatty acids

  1. Values are lsmeans ± SEM. Labeled means with no common letters differ within row (P ≤ 0.05). Metabolizable energy, ME; monounsaturated fatty acids, MUFA; polyunsaturated fatty acids, PUFA; saturated fatty acids, SFA.
  2. 1ME was calculated as the sum of each of the energy nutrients multiplied by their digestibility coefficients and energy values [(crude protein × 0.85 × 18.8 kJ/g) + (crude fat × 0.90 × 39.8 kJ/g) + (carbohydrate × 0.70 × 17.6 kJ/g)].
