Extract

Genetic trends can be readily calculated from national genetic evaluation data. However, these reflect the combined decisions of all owners of recorded dairy cattle rather than a single policy followed on one farm over a long period of time. The Langhill herd maintained by SAC at its Crichton Royal Farm allows the study of the genetics of cows of average merit over a twenty-four year period.
