Objective        To compare blood physiological and biochemical parameters in Bama miniature pigs under different restricted feeding

and to investigate the effect of restricted feeding levels on blood physiological and biochemical parameters

in order to laid a foundation for animal standardized research in Bama miniature pigs.       Methods        Three hundred and thirty-six weaning Bama miniature pigs were randomly divided into a control group

a 80% of the diet group and a 50% of the diet group according to different restricted eeding. Blood samples were collected from the precava at 60 and 90 d

and seven blood biochemical parameters such as alanine aminotransferase (ALT)

total protein (TP)

total cholesterol (TCHOL)

triglycerides (TG)

UREA

creatinine (CREA) and glucose (GLU)

and ten blood physiological parameters such as white blood cell (WBC)

red blood cell (RBC)

hemoglobin (HGB)

platelet (PLT)

hematocrit (HCT)

mean corpuscular volume (MCV)

mean corpuscular hemoglobin (MCH)

mean corpuscular hemoglobin concentration (MCHC)

red cell distribution width (RDW)-SD and RDW-CV were determined. The differences of the parameters under different restricted feeding levels were compared.       Results        The blood physiological and biochemical parameters such as ALT

TP

UREA

CREA

RBC

HGB

HCT

MCH and MCHC were positively correlated with the restricted feeding levels

while those such as TCHOL

GLU

PLT

MCV

RDW-SD and RDW-CV were negatively correlated with the restricted feeding levels.       Conclusion        The blood physiological and biochemical parameters of Bama miniature pigs have significant differences under three restricted feeding levels

and we can get stable and standard blood physiological and biochemical parameters under 20% restricted feeding in this study.
