The best (busiest) time of year is here—summer! Summer means longer days, more sunshine, and, of course, warmer temperatures. We’ve already had a handful of 90+ degree days, but it’s important to stay on top of heat stress management. Everyone usually remembers that the milking herd needs additional cooling measures—shade, fans, sprinklers, etc. But it’s important not to forget about dry cows and heifers. While it’s not always possible to provide access to fans and sprinklers, make sure that these groups of animals have access to plenty of fresh water and shade at the very least. These animals are or are growing the future of the herd. Many research studies have shown that heat stress has many negative short- and long-term effects.

We are partnering with MDIA to host an on-farm education day in New Windsor on July 12th. See page 9 for more details. Additional educational opportunities that may be of interest are listed on page 15.
In this issue, we focus on calf scours, ketosis, and tips for improving hayfield productivity. Please contact me if you have any comments, questions, or suggestions (; 301-432-2767 ext. 324).

The Dairy Team Welcomes a Summer Intern

By Nathan Villiger University of Maryland Extension Summer Intern
Student Update

2022 Extension Intern, Nathan Villiger
Nathan Villiger, 2022 Extension Summer Intern

Hello everyone! My name is Nathan Villiger, and I am one of the University of Maryland Extension’s new summer interns. I currently attend St. Mary’s College of Maryland where I am pursuing a bachelor’s degree in environmental science with minors in political science and biology. For the next ten weeks I will be working with Sarah Potts, Amanda Grev, and Jeff Semler at the Western Maryland Research and Education Center as part of UME’s new Creating Leadership and Professional Development Through Extension Internship. Through this program I will be assisting Sarah, Amanda, and Jeff with ongoing research at various extension sites, as well as engaging in traditional extension outreach and developing my own professional skills. Though I am new to extension, I have worked on and around farms my entire life having grown up in Montgomery County’s agricultural reserve. My particular interests lie in hay and forage production, as well as grazing and pasture management. Thus, I am excited to work with Sarah, Amanda, and Jeff as they have several research studies that deal with these topics. In addition, I hope to contribute a few written pieces to Maryland Dairy News and other extension publications, and I am looking forward to learning more about Maryland agriculture!
