The composition of the egg was not affected by protein
intake (Table 6). Shell was slightly more than 10%
of the egg, yolk was approximately 25%, and albumen
was slightly less than 65%. Interior quality, as measured
by Haugh units, was not affected by protein intake. A
significant difference was found in egg composition in
the various periods. Yolk, as a percentage of the whole
egg, increased with time, and albumen percentage decreased.
Interior quality also decreased with time.
Treatment did not affect bird BW. The average BW
at the beginning of the experiment was 1.303 ± 0.029
