Farm data from 2009 and 2010 is being collected through the Penn State Profitability Assessment Dairy Tool from Pennsylvania dairy operations by Rebecca White of the Penn State Extension Dairy Team. According to White, preliminary data reveals that two-thirds of the farms had an economic loss due to low pregnancy rates and high average days in milk (DIM) had a greater economic loss per cow.
Higher average DIM for a herd can signal a reproductive problem and can lead to lower lifetime production per cow further reducing herd profitability. For example, a dairy herd with an average of 192 DIM and a gross milk price of $20.50, the estimated loss from the increased DIM (192 vs. 185) $89.04 per cow per year. For a 250 cow herd, the total loss would be $22,260 per year.
The Reproductive Drill-Down tool is a component of the Profitability Assessment Dairy Tool (PA Dairy Tool) and can be accessed at: http://www.das.psu.edu/research-extension/dairy/pa-tool/identifying-bottlenecks-to-higher-dairy/
