🐂MAY IS NATIONAL BEEF MONTH! 🐂

At the Grazingland Animal Nutrition Lab, we are celebrating the hard-working cattle producers who provide quality beef for our tables while practicing sustainable grazing management!
How we support beef producers everyday:

💩 Our lab analyzes f***l samples from grazing animals using Near Infrared Reflectance Spectroscopy (NIRS) to assist producers in monitoring their herds nutrition.

🖥️NUTBAL Software Application- After NIRS analysis, our NUTBAL system combines data on animal profiles, environmental conditions, pasture quality, and supplementation to generate performance reports. These reports estimate forage intake and nutritional requirements, helping determine if dietary needs are being met.

💵Economic Feed Management- The NIRS/Nutbal system helps producers identify “when, what, and how much to feed” to maximize cost-effectiveness based on their production goals.

🌾Grazing Management Guidance- Our services help producers track pasture forage quality to adjust grazing strategies and address potential forage limitations.

This National Beef Month, we are proud to provide scientific analysis that helps producers create high-quality beef while maintaining sustainable grazing practices!

At the GAN Lab, manure isn't a waste — it's important data that helps us understand grazing animal nutrition and support better management decisions in rangeland and pasture systems!

Great insights from the Beef Cattle Research Council on the value of manure in nutrient management!

💩 Cattle manure is a valuable source of organic matter as well as nitrogen, phosphorus, potassium, sulphur, magnesium, calcium and other nutrients.

🌱 Manure is spread naturally by grazing animals and can also be stored through stockpiling, composting or other means, and spread or applied to land later, according to regional regulations.

For all manure matters, check out our Manure & Nutrient Management web page:

Congratulations to NRCS on 90 years of impact! 🎉 We’re honored to contribute to their mission of supporting producers through science-based conservation and rangeland stewardship!

This week we celebrate our 90th anniversary. 🎊 Through the voluntary conservation actions of farmers, ranchers, and landowners across the country, and in partnership with soil and water conservation districts and a myriad of other partners working in every state and territory, together we've made tremendous progress in the conservation of natural resources on private lands throughout the United States. Join us on a trip down memory lane as we reflect on our founding, where we’ve been, and where we’re going: https://www.nrcs.usda.gov/our-agency/news/after-setting-roots-90-years-ago-nrcs-continues-to-grow-its-conservation-legacy?utm_campaign=042125nrcs90anniversaryblog&utm_source=USDA+Natural+Resources+Conservation+Service&utm_medium=social&utm_content=1745435708

At the Grazingland Animal Nutrition Lab, we are harnessing our power for our planet through science that creates agricultural solutions. Our research into grazing animals and their nutritional needs helps develop practices that benefit both livestock/wildlife and landscapes. By understanding the science of animal nutrition, we are contributing to a more resilient and sustainable planet today and everyday. Happy Earth Day! 🌎🌾🐂🦬🐐🦌

We were at the ASAS Southern/Western Section meeting last week in Arlington, sharing the work we’ve been doing at the GAN Lab and Sonora Research Station Endowment Fund.

Always a great opportunity to connect and represent our team!

Congratulations to our director, Dr. Doug Tolleson!!

Our Chief Scientist at the Sonora Research Station, Dr Doug Tolleson, has just been named to
the American Sheep Industry Association’s Production, Education, & Research Council. He joins Dr Jake Thorne at the San Angelo Research and Extension Center who serves on the Genetic Stakeholders Committee for the ASI.

Per ASI - The Production, Education and Research Council works on maintaining and improving
the health, productivity and competitiveness of the sheep industry. Members work with the U.S.
government and industry groups to prevent and control various animal diseases affecting sheep,
enhance genetic improvement, educate producers and others about proper sheep husbandry and
foster appropriate research and education activities.

This position will provide opportunities for Dr Tolleson to bring a small ruminant and rangeland
management perspective to his participation on the American Society of Animal Science’s
Public Policy Committee.

As you might imagine, public policy and how this affects production education and research is
currently in a dynamic state.

Stay tuned.

Our GAN Lab Director, Dr. Tolleson, and team recently traveled to Kansas to scan cattle noses with a portable backpack Near Infrared Spectroscopy (NIRS) machine. This research advances our understanding of cattle muzzle chemistry while showcasing innovative applications of NIR technology.
