Values are means of 6 replicates (10 birds per replicate).
Means with different superscripts within the columns are different (p < 0.05).
Meat yield refers to breast, thighs, wings, and drumsticks.
CSM low level: 4%, 8%, and 12% of complete diet introduced in the starter, grower, and finisher period, respectively.
CSM medium level: 5%, 10%, and 15% of complete diet introduced in the starter, grower, and finisher period, respectively.
CSM high level: 6%, 12%, and 18% of complete diet introduced in starter, grower, and finisher phases of growth, respectively
SEM, standard error of means; CSM, cottonseed meal.
