Cranial superficial epigastric (milk vein) and jugular venous blood pressure were measured in 8 cows with udder edema and in 3 normal control cows at least 2 weeks before parturition, at parturition, and 2 weeks after parturition. Cows with udder edema had a significant mean increase (P less than or equal to 0.05) in cranial superficial epigastric venous pressure at parturition when compared with pressures 2 weeks prepartum and 2 weeks postpartum. Unaffected control cows had an insignificant increase in cranial superficial epigastric venous pressure during these 3 periods of measurement. There was an insignificant increase in jugular venous blood pressure during the 3 periods of measurement in affected and control cows. A correlation was observed between mammary blood flow and cranial superficial epigastric blood pressure at parturition (r = -0.659, P less than or equal to 0.05).
在8头患有乳房水肿的奶牛和3头正常对照奶牛分娩前至少2周、分娩时以及分娩后2周，测量了颅部浅表腹壁静脉（乳静脉）和颈静脉血压。与产前2周和产后2周的压力相比，患有乳房水肿的奶牛在分娩时颅部浅表腹壁静脉压力平均显著升高（P≤0.05）。未受影响的对照奶牛在这3个测量期间颅部浅表腹壁静脉压力升高不显著。在受影响奶牛和对照奶牛的3个测量期间，颈静脉血压升高不显著。在分娩时观察到乳腺血流与颅部浅表腹壁血压之间存在相关性（r = -0.659，P≤0.05）。
