Effects of EPA/DHA Omega-3 in Partially Alleviating Heat Stress Effects – Dr. Daniel Rico

February 27, 2023

Research has shown that production losses during heat stress are not simply due to a loss in dry matter intake. In fact, the heat stress effects that are not due to lower intakes is a result of immune activation and the effects of inflammation. In this study recap, Dr. Daniel Rico from CRSAD in Quebec explains the findings of their latest research that explores EPA/DHA omega-3s as a possible method of reducing the inflammatory effects of heat stress.

What you will learn:

How they quantified the effects of immune activation vs. lost DMI due to heat stress in this study.
The effects of EPA/DHA omega-3 on the cows’ metabolism during heat stress, including improved insulin sensitivity and lower NEFAs.
Outcomes on improved milk production, lower rectal temperature and respiration rates in cows under heat stress with an increased supply of EPA/DHA omega-3.
