Heat stress affects unborn calves

According to Geoff Dahl, a dairy physiologist with the University of Florida in the US, unborn calves of cows experiencing heat stress will have lower birth and weaning weights, and might produce as much as 1 300 litres less milk during their first lactation. It is important to keep dry cows cool during periods of heat stress since this leads to better in-calving and after-calving performance. Many farmers are not aware that the impact of heat stress on unborn calves can last into adulthood. Dahl states: “Cooling is pretty important for the fetus”.
