No differences in blood samples were found out when the biochemical parameters in arterial and venous blood of dairy cows were compared before and after milking. Negative correlation coefficient (r = -0.3460) approaching the significance level was determined by comparing the values for milk yield on the day of sampling (in ascending phase of lactation) and protein content in venous blood after milking, and significant negative correlation coefficient (r = -0.3813) for daily milk yield and gamma-globulin concentration in venous blood before milking. The relationship between butterfat content on the day of milking and the values of alkaline phosphatase can be characterized by significant up to highly significant negative correlation coefficients in all three blood samples (r = -0.3232 to -0.3908).
在比较奶牛挤奶前后动脉血和静脉血的生化参数时，未发现血液样本存在差异。通过比较采样当天（泌乳上升期）的产奶量与挤奶后静脉血中的蛋白质含量，确定了接近显著水平的负相关系数（r = -0.3460），并且挤奶前静脉血中每日产奶量与γ-球蛋白浓度之间存在显著负相关系数（r = -0.3813）。在所有三个血液样本中，挤奶当天的乳脂含量与碱性磷酸酶值之间的关系可由显著至高度显著的负相关系数来表征（r = -0.3232至-0.3908）。
