Experimental Design
and Dietary Treatments
In this experiment, 1-d-old Ross male broiler chicks
were obtained from a commercial hatchery. The birds
were kept under continuous incandescent electric lamps
with basal diet and water available for ad libitum consumption
until they were 6 d old. A standard starter
corn soybean meal diet, which meets NRC requirements,
was fed from d 1 until the end of the experiment
(NRC, 1994). The composition and proximate analyses
of experimental diets are presented in Table 1.
