| Popis: | SUMMARY A survey of the results of metabolic profile tests on 191 herds is reported. The mean values for the concentrations of various blood components were similar to those determined in two previous surveys. In addition the importance of seasonal trends was established. Thus sodium concentrations were lower in summer than winter whilst urea, haemoglobin and albumin showed the reverse trend. These effects appear to reflect the input/output balances prevalent under indoor winter feeding as opposed to summer grazing conditions. Much of the variation in blood chemistry within season is due to differences between herds and to differences between lactational groups, which confirms the hierarchical structure of the Compton Metabolic Profile Test—namely that it is a test of blood chemistry of a lactational group within a herd, within a season. |
