^aControl group was fed a corn-soybean meal basal diet; CSM, cottonseed meal; CSM₂₅, CSM₅₀, CSM₇₅, and CSM₁₀₀ indicate that 25, 50, 75, and 100% of the protein content provided by soybean meal in the control diet was replaced with CSM respectively
BW Body weight, ADFI Average daily feed intake, ADG Average daily gain, F:G Feed to gain ratio, SEM Standard errors of the mean
