Montana, you’ve been amazing!

Between the Grazing Expo, Dr. Tolleson’s talk on Nutritional Monitoring of Grazing Animals: Old School and High Tech, meeting with ranchers, and connecting with customers, this trip was full of inspiration, learning, and great conversations.

We even wrapped up the evenings with live music and good company.

This year is extra special for us as we also celebrate the GAN Lab’s 30th anniversary—three decades of research, innovation, and service in grazing livestock nutrition.

Huge thanks to the Montana Grazing Lands Coalition for hosting such a special event!

August sampling ✅🐂🌾

We have officially reached the halfway point to our South Texas Nutritional Monitoring Project and we are excited to see the amazing results that come with it!

Being able to be in the field and see the changes in the pastures and cattle month to month is amazing and truly shows the amount of hard work it takes to raise such awesome herds!

We can’t wait to see what the rest of the sampling season has in store! 🐮🌾

Our team recently represented the Grazingland Animal Nutrition Lab at the 52nd Annual Sheep & Goat Field Day in San Angelo, TX, hosted by Texas A&M AgriLife Research & Extension. This year’s event was dedicated to Kerrville flood victims and brought together researchers, extension specialists, and industry professionals from across the region.🐏🐐

Our director Doug Tolleson, Associate Professor and Chief Scientist at Sonora Station, presented “Sonora Station Research Update,” sharing the latest findings from his many ongoing research initiatives.

During the research poster session, our talented team of recent graduates Dr. Camille Carey, Kimberly Tanguma, and Jessica Dudak, along with graduate student Timothy Lyons, presented their research findings to attendees. The interactive poster session provided an excellent platform for knowledge exchange and networking within the sheep and goat community. 🌾🔬

The sheep and goat field day was a great opportunity to share our research with fellow scientists and industry professionals. Proud of our team’s contributions to advancing knowledge in grazingland animal nutrition! 🤠

🦣 🦬Research Collaboration: SDSU West River Agricultural Research and Extension Center

🔬Dr. Tolleson, Director of the Grazingland Animal Nutrition Lab, recently traveled to South Dakota to collaborate with Dr. Jeff Martin and his team at the South Dakota State University West River Agricultural Research and Extension Center in Rapid City.

🦬Dr. Martin serves as the Bison Extension Specialist with the Center of Excellence for Bison Studies (SDState - Center of Excellence for Bison Studies). His research focuses on modern bison ecology and management, while utilizing historic and fossil samples to better understand current conditions.

🧪 The collaboration involves multiple projects applying near infrared spectroscopy to non-invasively and non-destructively analyze f***l samples, determining diet quality for both living and extinct grazers.

During the South Dakota visit, Dr. Tolleson examined bison herds, toured the SDSU Cottonwood Field Station with Dr. Jameson Brennan, and collected NIR spectra on fossil f***l samples from species including ground sloths, bison, and mammoths at the Hot Springs Mammoth Site.

🔍 Chute-side CSI: Determining Brand Alteration via Portable Near Infrared Spectroscopy

Dr. Tolleson, Director of the Grazingland Animal Nutrition Lab, was an invited speaker at the International Livestock Identification Association annual meeting in Gering, Nebraska, July 21-23. 🐄
The presentation drew approximately 100 attendees from the US, Canada, and Australia 🌎, including livestock law enforcement officers, brand inspectors, veterinarians and animal health professionals, ranchers and producers, state legislators, and the Director of the Nebraska Department of Agriculture.

🔑 With record high cattle prices, theft is on the rise. Branding remains the most reliable form of proof of ownership for livestock, and branded animals are much more likely to be recovered if stolen.

🔬The near infrared spectroscopy technique is a work in progress . Results indicate that accurately pinpointing a date of brand application is not currently achievable, but determining that a given brand has been altered is feasible.

The next step involves evaluating the technique in a real-world cattle theft case. Dr. Tolleson is working with ILIA to accomplish this objective.

📣Calling all customers, partners, and friends.

The Grazingland Animal Nutrition Lab will be collecting donations to help our Central Texas neighbors recover from the recent devastating flooding event that has impacted the Hill Country communities. The catastrophic floods have caused tremendous loss of life and property damage, leaving families and volunteers in urgent need of basic supplies and support.

Every donation will make a meaningful difference in helping our neighbors rebuild after this tragedy. Together, we can show the strength of our Texas community spirit during this difficult time.
