Concentrations of albumin and total protein in cattle blood plasma depending upon locality and seasonal changes

Abstract

The study was aimed at determining plasma concentrations of albumin and total protein (TP) in 480 dairy Holstein-Friesian breed cows on differentnlocalities in Bosnia and Herzegovina and in different seasons (diet conditions). The samples were taken from the cows in lactation, postpartum period within 15 days from calving, and the dry period. Seasonal variations affected both investigated parameters. Differences among localities were determined during summer for TP concentrations and during winter for albumin concentrations. Differences were considered statistically significant at p<0,05. Results show significant influence of the diet conditions on plasma concentrations of examined parameters so the conclusion is their constant monitoring during the production period is required.
