[Use of the computer in the study of relations of indicators in the metabolic profiles of dairy cows].
Fifty dairy cows with metabolic alkalosis and forty-eight dairy cows of a control group were subjected to a metabolic profile test with 30 parameters. The results of analyses were confronted with reference values in histograms. We calculated mutual correlation coefficients for all parameters of dairy cows of the two groups. The correlations between selected pairs of parameters were represented diagrammatically in a form of correlograms. We demonstrated that the values of certain parameters being approximately identical, the correlations in group A of dairy cows (with alkalosis) varied in a different way from the correlations of the control group. It is seen from the results that the confrontation of the values of a parameter with reference values need not be in all cases a reliable criterion of evaluating the internal environment in dairy cows. We processed the metabolic profiles of the two groups by a multidimensional analysis of principal components. The dairy cows of the two groups clearly differentiated from one another according to the internal environment regarding the used parameters. We draw attention to a possibility of computerizing the diagnostic significance of the metabolic profile parameters.
