^a,bMeans with different superscripts in a row differ significantly (P < 0.05). T = tendency to be influenced by treatment.

Abbreviations: CWP, cowpea; SBM, soybean meal; SIL, small intestine length; SIW, small intestine weight.

Data are means of 6 birds per treatment.

Bacillus subtilis, ATCC 6051a strain: 5.0 × 10¹¹ CFU/g⁻¹ feed.

Data were analyzed as a 2 × 2 factorial arrangement.

⁴

Represents as weight (g) of without head, neck, feet, and viscera carcass as 100 g of live body weight.

^5,6

Calculated as weight or length (g or cm) of organs as 100 g of carcass weight.
