摘　　要：目的测定不同限饲水平下巴马香猪重要血液生理、生化指标,探讨限饲对血液生理生化指标的影响。方法将336头断奶巴马香猪根据不同限饲水平按完全随机法分为对照组、80%日粮组和50%日粮组,每组112头,在60日龄和90日龄前腔静脉采集血液样本,对重要的10项血液生理指标和7项血液生化指标进行测定,统计不同限饲水平下指标的差异。结果血液生化指标中ALT、TP、UREA和CREA指标值随着限饲水平的上升而上升;而TCHOL和GLU指标值随着限饲水平的上升而下降(P<0.05)。血液生理指标中RBC、HGB、HCT、MCH和MCHC指标含量随着限饲水平的上升而上升;而PLT、MCV、RDW-SD和RDW-CV指标含量随着限饲水平的上升而下降(P<0.05)。结论巴马香猪在3个限饲水平下,血液生理、生化指标存在明显差异;按80%日粮限饲的巴马香猪更能获得稳定标准的巴马香猪血液生理、生化指标。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.
