PL0, PL2.5, PL5, PL10: commercial feed supplemented with peptidoglycan at 0, 2.5, 5, and 10 g/kg. WBC: White blood cells, RBC: red blood cells, LYM: lymphocytes, MID: monocytes, GRAN: granulocytes, HCT: hematocrit. T2 and T4 were samplings after 2 and 4 weeks of feeding trial. Data was presented as mean ± SD, the different letters denote the significant difference between treatments (p < 0.05).
