Publication Date: N/A Interpretive Summary: Demands to lower
dairy producers' milk-testing costs, to increase technicians'
ability to handle more herds, and to reduce disruption of normal
milking routine have spurred investigations and implementations
of alternative milk-testing methods that have the credibility of
official Dairy Herd Improvement record keeping plans. Yield on
test day reported as a percentage of the actual milk shipped has
been proposed by dairy industry groups as a statistic for
monitoring the accuracy of alternative record keeping plans.
This statistic was examined to determine 1) if its properties
differed with herd size, production level, and record-keeping
plan and 2) whether adjusting individual daily milk yields for
this statistic would increase the accuracy of genetic
evaluations for milk yield. Frequency distribution of the
statistic revealed a normal distribu
