Data are least square of mean of eight replicates with two cages (five birds per cage).
Mean values with different superscripts within the same row differ significantly (p < 0.05).
Control, fasting group; CZn, group fed commercial layer diet with 8,000 ppm zinc; MZn, group fed induced molting diet with 8,000 ppm zinc.
