Swine producers now have new science-based tools to help manage heat stress during the summer months. Iowa State University Extension and Outreach has released two new publications designed to support pork producers in protecting animal health and productivity during periods of high temperatures.
The resources titled “Heat Stress in Swine Production: Breeding Herd Considerations” and “Heat Stress in Swine Production: Basic Research” are available for download through the ISU Extension Store. These publications were developed to help farmers better understand how heat stress affects pigs and what steps can be taken to reduce its impact on farms.
According to researchers heat stress causes major financial losses across the United States pork industry. Annual economic losses are estimated to exceed five hundred twenty million dollars.
High temperatures can reduce feed intake, slow growth and negatively affect reproduction. By following proven heat mitigation practices, producers can help maintain feed efficiency and overall animal performance.
Mark Storlie extension swine specialist at Iowa State University and author of the publications explains the seriousness of the issue. “Heat stress causes pigs to focus on survival instead of growth or reproduction,” said Mark Storlie extension swine specialist at ISU and author of the publications. “Minimizing heat stress can improve animal growth performance and productivity, positively impacting a pork producer’s bottom line.”
The first publication focuses on breeding herds and explains how heat stress can reduce reproductive success in sows and boars. It provides practical tools for identifying heat stress early, explains updated research on ideal temperature ranges, and includes guidance on ventilation design and additional cooling options. These strategies are especially important during breeding and pregnancy stages.
The second publication highlights research findings from a trial conducted by former graduate student Tori Rudolph. This study examined how heat stress affects different types of pigs. Results showed that gilts and barrows respond differently, with changes observed in muscle tissue and blood health indicators. These findings help producers better understand biological stress responses.
Together, these publications offer clear and practical guidance for farmers. By using research-backed strategies, pork producers can protect animal welfare, improve efficiency, and reduce costly losses during the hottest months of the year.
