In TB piglets, the hemoglobin (HGB) and hematocrit (HCT) levels were higher (p < 0.05) at 24 days of age than at 1, 10, and 21 days of age, whereas the coefficient of variation of red blood cell volume distribution width (RDW-CV) and standard deviation in red cell distribution width (RDW-SD) levels were lower (p < 0.05) at 1 and 24 days of age than those at 10 and 21 days of age. Here, CYGB is linked to tuberculosis.
