Each least squares mean represents 8 observations except the control diet (n = 7).
Avilamix (avilamycin 20 g/kg, CTCBIO, Seoul, Korea) was supplemented at 0.1%.
BacterPhage (CTCBIO) was supplemented at 0.2%. The product contained a mixture of BP consisted of Clostridium perfringens types A and C, Escherichia coli (f41, k88, and k99), Salmonella spp. (Salmonella choleraesuis, Salmonella derby, Salmonella enteritidis, and Salmonella typhimurium), and Staphylococcus aureus. The BP product contained 10⁹ plaque-forming units per gram.
