Heat stress remains a costly, persistent challenge in U.S. beef production. Annual losses exceed $370 million annually, and the economic impact often begins before producers see obvious clinical signs. What feels like mild heat and humidity to humans may still impact cattle comfort and performance.

Each year, environmental stressors such as drought, excess moisture, high temperatures, humidity and insect damage predispose crops to mold growth and subsequent mycotoxin contamination. Mycotoxins are secondary metabolites secreted by various fungi species found on crops grown for livestock feed.

The dairy and beef industry can collaborate to solve the challenges associated with feeding dairy cross calves today.
