摘　　要：为了解泌乳期和干乳期荷斯坦奶牛血液生化指标的变化规律,进一步指导奶牛实际生产工作,本试验使用一次性注射器采集奶牛颈静脉血液置于2 mL离心管中,标记并记录每头奶牛耳号以及采样日期,采用全自动血细胞分析仪对加抗凝剂的全血进行血常规和血液生理生化指标测定。结果显示:白细胞数目在泌乳前期会有一定程度升高(P>0.05),血红蛋白含量在整个泌乳时期变化均不显著(P>0.05);总蛋白量(TP)在泌乳盛期达到高峰,碱性磷酸酶(ALKP)在泌乳前期量最多,丙氨酸转氨酶(ALT)在泌乳盛期降低,在泌乳盛期血糖(GLU)含量显著高于其他泌乳时期(P<0.05)。The aims are to understand the change rule of blood biochemical indexes of Holstein cows in the lactation and dry milk period, and guide the actual production. In this experiment, jugular venous blood of cowwas collected with disposable syringe and preserved in 2 mL centrifuge tube, ear number of each cow andsampling date were marked and recorded. After that, blood routine and blood physiological and biochemicalindexes in the whole blood with anticoagulant were detected by an automatic blood cell analyzer. The resultsshowed that the number of white cells increased to some extent in the early lactation period(P>0.05).Hemoglobin content had no significant change in the lactation period(P>0.05). Total protein(TP) peaked inthe peak lactation period. The number of alkaline phosphatase(ALKP) was the maximum in the early lactationperiod. Alanine aminotransferase(ALT) reduced in the peak lactation period. The content of blood glucose was significantly higher in the peak lactation period than that in other lactation period(P<0.05).
