We know feedlot dust affects cattle health and performance. 2022 weather forecasts indicate drought conditions are likely in prime cattle feeding geographies. Research helps us understand the effects of dust and what to do about it.
Dust is not just dirt and sand that becomes airborne. Groups of cattle produce organic dust and particulate matter at a relatively high concentration daily when manure is dry. These materials increase the risk of bovine respiratory disease and acute interstitial pneumonia.
Management protocols to reduce dust incidence include maintaining a greater stocking rate, permanent and portable sprinkler systems, and altering feeding schedule.

INSIGHTS: Data from nearly a million cattle on 30 feedlots from 2015 to 2017 coincided with the seasonality of dust production. Total and respiratory death losses were highest from June to August.
