Extract

The Compton Metabolic Profile Test was designed to monitor the health of dairy herds, but the possibility is now being investigated of using blood profiles as an aid in the identification of prediction of cows with superior production potential. The problem of determining whether blood profiles can be used in this way, however, is likely to be complex. Even if relationships can be found between individual blood profiles of cows and their current performance, it need not follow that such relationships could be predicted from samples collected earlier in life. Further, although it has been shown that cows maintain individual blood profiles over fairly long periods of time (Kitchenham and Rowlands, 1976) the important characteristic may not be the mean concentration of a blood constituent maintained by a cow, but the ability of a cow to maintain normal concentrations during periods of stress.
