Blood serum proteinograms in pregnant and non-pregnant cows.

Abstract

The proteinograms of non-pregnant and pregnant cows were studied.Significant differences in total protein, albumin, globulin, a -globulin and g -globulin concentrations (P<0.01) between non-pregnant and pregnant cows during the eighth month of pregnancy were recorded.The differences in concentrations of b -globulin and in the A:G ratio were not significant (P>0.05).The comparison of results recorded in the eighth and in the ninth months of pregnancy showed that the globulin, a -globulin and g -globulin concentration significantly decreased in the ninth month of pregnancy (P<0.01), the concentration of total serum protein also decreased significantly (P 0.01-0.05),albumin concentration (P>0.05) and A:G ratio (P>0.01)significantly increased, whereas in b -globulin concentration the difference between the values recorded in the eighth and in the ninth months of pregnancy was not significant (P>0.05).
