Lower corn prices may help cattle feeders

Cash corn prices in Kansas were over $7 per bushel in the first four months of 2023, peaking in February at $7.35 per bushel.

The average corn price in August, the latest month for which data is available from U.S. Department of Agriculture’s National Agricultural Statistics Service, was $5.70 or 22% lower than the average corn price in February.  

Corn futures prices for 2024 currently range from $5 to $5.20 per bushel. Thus, corn prices are expected to remain below the levels experienced in the last couple of years for the foreseeable future.  

Feeding cost of gain

Feeding cost of gain is sensitive to changes in feed conversions, corn prices, and alfalfa prices. Figure 1 illustrates feeding cost of gain from January 2013 to August 2023. In August 2023, corn and alfalfa inventory prices were $7.04 per bushel and $273 per ton, respectively. 

After averaging $125 per hundredweight in 2022, feeding cost of gain averaged $147 and $145 per hundredweight. for the first and second quarters of 2023. Feeding cost of gain in August was $141.83. It is important to note that since this estimate was made corn prices have continued to decline 
Feeding of gain for the rest of 2023 was estimated using early October projections of corn and alfalfa prices, and seasonal average feed conversions. Because feeding cost of gain is computed using corn prices from the time cattle are placed to the time they are sold, corn prices experienced earlier this year will impact feeding cost of gain for the next several months.

With this in mind, feeding cost of gain for the third quarter of 2023 is expected to range from $134 to $143 per hundredweight, with the highest cost occurring in July. For the fourth quarter, feeding cost of gain is expected to range from $115 to $130 per hundredweight. Feeding cost of gain for the first six months of 2024 is expected to range from $103 to $112 per hundredweight.  

Is it possible for feeding cost of gain to drop below $100 per hundredweight? The answer is yes, but this is not likely to occur unless the corn price this fall and winter drops below $4.50 per bushel.

Sensitivity of feeding cost of gain to changes in corn prices

To determine the sensitivity of feeding cost of gain to changes in corn prices, alfalfa prices, and feed conversion, a regression using data for the last ten years was estimated. Results are as follows: each 10-cent increase in feed conversion increases feeding cost of gain by $1.33 per hundredweight, each 10-cent per bushel increase in corn prices increases feeding cost of gain by 96 cents per hundredweight, and each $5 per ton increase in alfalfa prices increases feeding cost of gain by 53 cents per hundredweight. To more fully understand the impact of feed conversion, corn price, and alfalfa price on feeding cost of gain, we computed coefficients of separate determination These coefficients can be used to measure the influence of each independent variable upon the dependent variable.  

The sum of the coefficients of separate determination for each variable equals the R-square goodness of fit measure, which was 0.959 for the feeding cost of gain regression. This goodness of fit statistic indicates that 95.9% of the variation in feeding cost of gain was explained by fluctuations in feed conversions, corn prices, and alfalfa prices. Computed coefficients of separate determination indicated that corn price explained approximately 76% of the variation in feeding cost of gain. 
 
To further examine the sensitivity of feeding cost of gain to changes in the corn price, let’s use the farmdoc Price Distribution Tool and the March 2024 corn futures contract. The mid-point price is currently about $5 per bushel. The 25% and 75% percentile prices are approximately $4.60 and $5.40, respectively. Feeding cost of gain at the mid-point price is $107 per hundredweight. At the 25% and 75% percentile corn prices, feeding cost of gain would be $103 and $111 per hundredweight, respectively. This analysis strengthens the argument made above that corn price would need to drop below $4.50 for feeding cost of gain to fall below $100 per hundredweight. 

Summary and conclusions

Corn prices have declined substantially since the first half of this year. This article examined the impact of higher corn prices on feeding cost of gain for cattle finishing. Using projected corn prices, feeding cost of gain is expected to decline from $142 per hundredweight in August to $114 in December, and then remain in the $103 to $112 per hundredweight range for the first 6 months of 2024. However, it is important to note that each 10-cent change in corn price results in a change feeding cost of gain of 96 cents per hundredweight. Also, it would not take a particularly wide swing in corn prices to change our projections.
