Mammary blood flow measurements associated with the development of bovine udder edema.
Mammary blood flow (MBF) and mammary plasma flow (MPF) were measured by an antipyrine absorption method in 8 cows affected with udder edema and 3 healthy (control) cows at least 2 weeks before parturition, at parturition, and 2 weeks after parturition. Cows with udder edema had a significant decrease in MBF at calving compared with the control cows (P less than or equal to 0.05), whereas there was no significant difference (P greater than 0.05) in MBF between affected and control groups 2 weeks before or 2 weeks after parturition. Cows with udder edema also had a decrease in MPF at parturition that was not statistically significant (P greater than 0.05) when compared with that in the control cows.
