¹⁾Least squares means for seven replications per treatment.

²⁾B0, 0% barley was supplemented in each phase; B10, barley 10%; B20, barley 20%; B30, barley 30%.

³⁾Standard error of means.

⁵⁾Diarrhea incidence: 0 (no occurrence) to 4 (all pigs diarrhea); Data were measured by average total diarrhea incidence during each phases.
