Values are means of 6 replicates (10 birds per replicate).
Means with different superscripts within the columns are different (p < 0.05).
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.
CSM, cottonseed meal; G + P, gizzard and proventriculus; Pan, pancreas; SI, small intestine; SEM, standard error of means.
