Accuracy of computing comparative standards for dairy performance in relation to number of animals. 1. Development and evaluation of the model

, : Accuracy of computing comparative standards for dairy performance in relation to number of animals. 1. Development and evaluation of the model. Archiv fur Tierzucht 15(6): 399-405

This work was undertaken to devise a standard procedure for the evaluation of dairy characters in a cattle population. It is shown that for a given required degree of accuracy, the min. number of animals in the test sample will increase steeply as the heterogeneity of the base population increases. Unless the population is unusually homogeneous, 10-15 animals will yield a result with a CV of more than or equal to 17%.
