^a,b,cWhere there is an overall diet effect, values within rows with differing superscripts are significantly (P<0.05) different.

¹ CPO, EL, CPLO and MR are diets containing 350 g oil/day equivalent of calcium salts of palm oil, extruded linseed, calcium salts of palm and linseed oil and milled rapeseed, respectively.

² Refers to the significance of overall effect of period and diet.

³ SEM for n=20 measurements.
