At 5, 10, and 17 wk of age, the relative weight (RW,
% BW) of the GIT and the gizzard, and gizzard digesta
content were lower (P < 0.05 to P < 0.001) and
gizzard pH was higher (P < 0.05 to P < 0.001) in pullets
fed crumbles than in pullets fed mash. Energy concentration
of the diet did not affect any of the GIT
variables studied. In summary, feeding crumbles improved
pullet performance and reduced the RW of the
GIT and gizzard, and increased gizzard pH at all ages
