Calculate the Impact of a 4th Lactation Cull Rate

Based on graph data from a research study on 90,000 cows published in the Journal of Dairy Science, we have created a worksheet so you can calculate the impact of a 4th lactation cull rate on your herd.


The financial impact of lowering the cull rate and increasing the 4+ lactation cows in a herd can be significant. Use the area below to estimate the cost per year cull rate impact from using sand or rubber-filled mattresses.
