Cows and climate change

Kansas State University is leading a team of numerous university and government researchers involved in a five-year study looking at the best ways for the beef cattle industry to sustain future productivity through potential changes in climate.

Probably the most frequently asked question I have been getting relates to how much the drought is adding to herd liquidation in 2021. It’s a difficult question for several reasons. In the first place, we don’t know what the industry would have done in the absence of drought this year. Having decreased the past two years from the 2019 peak, would the industry have continued liquidation in 2021 in any event? The turbulence from the pandemic and other black swan events makes this an even more difficult question. 

Pete’s Comments: Leverage will return

What we do know is that beef cow slaughter is up 8.7 percent year over year through mid-August. If we assume the current levels of year-over-year increases continue for the remainder of the year, it implies an annual beef cow slaughter of 3.55 million head. That would be a net culling rate of 11.4 percent, the highest beef herd culling rate since 2011. 

The average culling rate the past two years, since the cyclical peak in 2019, has been 10.25 percent. Over the past 35 years, across cycles of expansion and liquidation, the average herd culling rate has been 9.65 percent annually. 

Increasing the resilience of livestock operations

However, because the drought started so early in the year (carried over from last year), it is likely that beef cow slaughter was shifted earlier in the year. Producers likely have already culled cows that would have been culled later in the year anyway. I doubt the 8.7 percent year-over-year beef cow slaughter rate will persist for the remainder of the year. Nevertheless, the drought continues unabated, and cow slaughter rates will likely remain strong. 

Cow slaughter is only part of the story about herd liquidation. It is less clear at this point in the year what is happening with heifer retention. The January cattle inventory report showed beef replacement heifers were 18.7 percent of the cow herd, a level that would support stable herd inventories. The total number of beef replacement heifers (which includes heifer calves and coming first-calf heifers) and the subset of heifers calving in 2021 were both fractionally higher year over year in the January numbers. 

Cattle markets in state of change

No doubt producers in drought areas have had to adjust replacement heifer numbers along with cows. Some heifer calves that were indicated as replacements in January likely were shifted into feedlots. It is not clear how many. Heifer slaughter is up 1.4 percent year to date over last year, but year-over-year comparisons are difficult because of pandemic impacts last year. Coming first-calf heifers in January may have gotten sold out of drought areas and moved to other parts of the country. The July cattle report showed a 2.3 percent decrease in beef replacement heifers.

Finally, there is the question of how producers not in drought areas have responded in 2021. Forage conditions have been good in some regions, and it is not clear if producers may be holding more cows and heifers to offset some of the drought region impacts. In short, we don’t know what would have happened in the absence of the drought, and we don’t know for sure how the remainder of the year will finish. 

After playing with lots of numbers and assumptions, my best guess at this point is that the drought has added one-half to 1 percent of additional beef herd liquidation this year. Derrell S. Peel, Oklahoma State University Extension livestock marketing specialist
