Lactational performance in high-yielding dairy cows has its limits in metabolic processes. Energy metabolism is maintained by mobilization of body reserves via hormonal regulation, resulting in lipolysis and sometimes ketoacidosis. For characterization of such conditions the intraruminal and intravascular application of glucose and volatile fatty acids was used in ruminant physiology. On the other hand the results of such experiments were correlated to actual and potential milk yield. For this investigation pairs of monozygous Holstein Friesian twins were tested as heifers and as cows by intravenous infusion of glucose, propionate and butyrate after 18 hours of feed withdrawal. Insulin, growth hormone, glucose, free fatty acids and beta-hydroxybutyrate were measured before, during and up to 4 hours after infusion of substrates. Each substrate caused a transient change in plasma concentrations of metabolites and hormones. Differences between heifers and cows are discussed with the time series of the mean concentrations. The reaction profile of each animal was characterized by different parameters. Analysis of these parameters revealed a close relation between hormones and metabolites even under the conditions of the load-test.
