Feed Value Calculator

A valuable tool used to determine the lowest-cost feed options for cattlemen.

Feed costs exceed 50% of annual beef cattle production costs, and with the current market situation, the pressure to determine the most cost-effective feedstuffs has become even more important.

South Dakota State University (SDSU) Extension has developed a feed value calculator to compare protein and energy supplement options. The spreadsheet allows producers to select supplemental feeds and compare them to baseline feeds. The benchmark for energy supplements in this spreadsheet is corn, whereas for protein supplements it is soybean meal [44% crude protein (CP)].


Using the calculator
To generate the most accurate results, producers should have feeds analyzed and should include the actual laboratory results in the spreadsheet. With byproduct feeds, analysis can vary significantly from batch to batch. These differences may alter the ration, which affects cattle performance and ration cost.

The spreadsheet compares costs per ton based on nutrient concentration. It then calculates how much to pay for each feed when compared to corn or soybean meal. For an accurate comparison, delivery and storage costs for each feed in dollars per ton should be included in the calculation.


Questions to consider
Questions that need to be addressed:

Dry distillers’ grains (DDG) for example could be available at your local elevator for $175 per ton, whereas wet distillers’ grains (WDG) sells for $44 per ton at the ethanol plant that is 100 miles away. Using the $175 and $44 values in the spreadsheet, WDG appears to be more cost effective. However, if the WDG is 100 miles away, the freight charge could change the economics. If the freight is $4.25 per loaded mile on a 26-ton load of WDG, freight will add approximately $16.35 per ton. This makes the cost of WDG $682 per ton of protein vs. $632 per ton of protein for the DDG.


The bottom line
This spreadsheet is a starting point for determining the least-cost feedstuff, but producers need to consider the storage and delivery costs and currently owned equipment. While an alternative feed may fulfill your least-cost ration needs, the additional costs of storage, hauling or equipment changes may deem traditional rations as the “best” for the operation. Producers need to make the decision to change, or not, the feeds used in their rations based on careful analysis.
