Measured outcomes from commercial feedlot and dairy systems under heat stress conditions.
In 2017 we compiled the breeding records from dairies in the Midwest and the Southwest regions of the US.
The heifers in this trial were on good pastures with plenty of shade and water. The experimental group received 350 mg of 454 per head per day in their feed and the control group received no 454.
