LZ-CB, low-Zn (7.8 μg Zn/g DM) cocoa butter (CB) diet fed free choice; HZ-CBR, high-Zn (53 μg Zn/g DM) CB diet fed in restricted amounts equivalent to the intake of the LZ-CB diet; LZ-SF, low-Zn (7.8 μg Zn/g DM) safflower oil (SF) diet fed free choice; HZ-SFR, high-Zn (53 μg Zn/g DM) SF diet fed in restricted amounts equivalent to the intake of the LZ-SF diet; HZ-SF, HZ-SF diet fed free choice.
Values are means ± SD, . Labeled means in a row without a common letter differ by 1-factor ANOVA followed by Tukey’s multiple-comparison test, .
Bifactorial ANOVA of the LZ-CB, HZ-CBR, LZ-SF, and HZ-SFR diet groups.
1-factor and bifactorial ANOVA after logarithmic transformation of the data.
BWG, body weight gain; DM, dry matter; ME, metabolizable energy.
