Serum protein electrophoretic pattern in dairy cows during the periparturient period

Abstract

This study was aimed at the evaluation of changes in the concentrations of serum protein fractions in 10 clinically healthy dairy cows in the period from 1 week before to 6 weeks after calving. Serum was analysed for total protein concentrations, and the relative and absolute values of protein fractions – albumin, alpha1- (α1), alpha2- (α2), beta1- (β1), beta2- (β2), and gamma- (γ) globulins. The concentrations of total proteins increased significantly from week 1 before parturition till the end of the sixth week of lactation (P
