Dairy Webinar Addresses Dry-Period Heat Stress

The effects of dry period heat stress on the lactating dairy cow is the topic of the Dairy Cattle Reproduction Council’s (DCRC) next webinar. The July 11 DCRC webinar starts at 1 p.m. Central time. University of Florida’s Geoff Dahl will share key strategies to help dairy cows beat the heat.

To register for this webinar, go to: www.dcrcouncil.org/webinars and follow the prompts. As the webinar approaches, you will receive an e-mail with information on how to log in to participate. If you are a DCRC member and cannot attend the live program, you may access the webinar at dcrcouncil.org.

“Heat stress not only impairs lactating cows, it also challenges dry cows and their calves,” said Dahl. “Dry period heat stress negatively affects the performance of dairy cows during the subsequent lactation. Plus, heat stress weakens immune status and harms mammary gland development.”

A recent study (Ferreira et al., 2017) estimated the economic losses on a per cow basis for the states of Florida and Texas at $337 and $383 per cow per year, respectively. The same study valued U.S. dairy industry economic losses at as much as $810 million per year.

During the one-hour webinar, Dahl will discuss heat abatement strategies that improve dairy cattle immune function and ultimately dairy farm profitability. Key topics include cooling systems, genetic selection and diet manipulation.

Each 2018 DCRC webinar provides one American Registry of Professional Animal Scientists (ARPAS) continuing education unit (CEU). To report ARPAS CEUs, go to: www.arpas.org/Membership/CEUs/Report-CEUs.

The Dairy Cattle Reproduction Council is focused on bringing together all sectors of the dairy industry – producers, consultants, academia and allied industry professionals – for improved reproductive performance. DCRC provides an unprecedented opportunity for all groups to work together to take dairy cattle reproduction to the next level.
