Following the ADSA 2025 Annual Meeting, I had the opportunity to visit the University of Kentucky in Lexington, where I was warmly welcomed by Dr. Harmon and Dr. Trotta. They kindly guided me through their laboratories and research farm, even while in the midst of preparations for relocating to a new research facility next year.
The university’s research environment was highly impressive. Their laboratories are equipped with a wide range of analytical instruments, including equipment for proximate composition analysis, organic acid measurement, and in vitro digestion trials. These resources provide a robust foundation for conducting advanced research in ruminant nutrition.
I also had the chance to tour the university’s experimental farm, which is currently undergoing expansion with new buildings under construction. The farm is extensive and home to not only beef cattle, but also pigs and poultry. One particularly remarkable aspect was the presence of multiple fistulated cattle, which allow for direct sampling of digesta from different parts of the digestive tract. This setup creates an ideal environment for evaluating the impact of feed components, especially in the lower gastrointestinal tract.
Drs. Harmon and Trotta primarily focus on studies related to starch digestibility and utilization in beef cattle. Since starch accounts for nearly 50% of the energy supply in feedlot diets, improving starch utilization is essential for enhancing growth performance and feed efficiency. Research in this area plays a critical role in optimizing nutrition strategies and reducing nutrient losses.
This visit provided a valuable opportunity to observe their facilities firsthand and gain insights into current research practices in the U.S. I hope to maintain this connection and look forward to greeting them again at future academic meetings.
