[Quantitative determination of blood-plasma protein fractions using micro-agar gel electrophoresis in highly pregnant dairy cows close to the day of delivery].
Ten clinically intact Jersey dairy cows in advanced pregnancy were examined and tested over a span of three hours before to seven hours after parturition. Blood was sampled from them in intervals of ten tp 20 minutes, and the blood plasma was checked total protein and the "classical" fractions. The average total protein value of the plasma samples was 6.5 g/100 ml. The albumin and alpha 1-fractions were inversely proportional the psi-globulin concentrations before, during, and after parturition. The albumin values were on a declining trend three hours prior to parturition and recommenced to rise ten minutes prior to parturition. They were relatively constant after parturition. The pri-globulins went up slightly prior to parturition, but that rise remained statistically unsecured. It is assumed that in a certain period of time from before to somewhen after parturition change of the fractions is caused by the corticoids and sexual hormones.
