[Genetic markers in the blood and their relation to metabolic parameters in dairy cows]

A relationship between the genetic markers of blood (blood groups, serum polymorphic proteins) and the clinico-chemical parameters was studied in the dairy cows of the Slovak Pied breed. Antigens belonging to systems A, B, C, F, S, R, T, Z and the polymorphic traits genetically controlled from loci Tf, Cp, Am and Hb were identified in all the animals subjected to testing. The values of the parameters of acid-base balance and concentration of 13 metabolic components were repeatedly determined in the experimental period. The results of the F-test indicated that there were no significant differences in the values of any of the tested parameters between the phenotypes of the A, J, Am, Tf and Cp systems. Of the 21 parameters tested, statistically significant differences were found in 11 parameters between some alleles of the C, FV, T, Z and Hb systems.
