KemTRACE® Chromium: Your Tool to Counter Heat Stress



In Canada, heat stress can cause milk loss up to 3.5 kg/day.1 The inability of a cow to dissipate heat effectively compromises their ability to function normally.2 Evidence suggests insulin action is a key component of heat stress response.3 Chromium supplementation has been shown to:


  • Increase insulin sensitivity and glucose utilization4
  • Improve dry matter intake (DMI) in heat stressed cows5
  • Improve DMI during heat stress to help maintain milk production5

Supplemental Chromium Impacts Milk Yield during Heat Stress

Response in daily milk yield, kg/h/d and dry matter intake, kg/h/d compared to the control within the study.
*Denotes significant difference from control.
