  • Values are means ± standard deviation (s.d.). For N values, see Table 1

    DEU=daily energy use; % DEU fat=% contribution of fat to DEU

    Bold type indicates a significant difference between groups (P<0.05)

  • * Refers to protein used in metabolism, i.e. values after protein used in moulting was removed from calculations
