Brief Summary of Minutes

• The meeting was held in Fort Collins, Colorado, by Colorado State University. The committee was welcomed by Dr. Carolyn Lawrence-Dill, dean of the College of Agricultural Sciences, and Dr. John Wagner, professor emeriti. After the welcome, the group conducted introductions of participating faculty as well as graduate students in attendance. The group toured the CSU Global Food Innovation Center and learned about their research and community outreach programs.


• Planning was discussed for 2026 meeting. The committee agreed that the University of Illinois will host the 2026 meeting in Urbana, IL on May 18-20. Tentative plans were made for 2027 in the Texas panhandle co-hosted by Texas A&M Agrilife and West Texas A&M.


• Administrative update was provided Dr. Steve Loerch. He commended the committee on the outstanding meeting attendance and continued growth of the committee through new members. He also provided an update on reporting guidelines.


• A report from USDA was provided by Amber Campbell. She is the new national program leader for the Nutrition, Growth, and Lactation program. She provided the committee additional context for changes at USDA with new executive orders and delays with prior reviews and request for proposals.


• Sixteen station reports highlighted reported progress toward the committee objectives while facilitating discussion of future work still needed to address the objectives.


• On May 20, the committee toured the Colorado State Climate Smart Research Facility at the Agricultural Research, Development, and Education Center. In the afternoon, the group toured the Kuner Cattle Feedlot and the Harper Sheep Feedlot.

Accomplishments

<p>Cattle are being fed to larger weights much more efficiently. However, public concern over the use of traditional technologies such as growth promotants and antibiotics has challenged the beef industry. Members of the NCCC-308 multistate group are investigating the role that stress and digestive processes play in disease prevention and are developing new feeding strategies and feed additives that improve animal health, increase growth, and enhance meat quality.</p>

Impact Statements

1. • Feeding palm oil improves feed efficiency similar to corn oil without compromising beef quality and shelf life, thus can be fed to feedlot cattle as a relatively new fat source that is likely more economical than traditional fat sources. In addition, feeding oil decreases enteric methane by about 10%.
2. • As a result of NCCC308 discussions, a multi-additive drench was tested in high-risk cattle and was observed to reduce mortality by more than half.
3. • A combination of gut barrier dysfunction and a viral respiratory disease challenge elucidated impacts on feed intake and the acute phase protein response in feedlot beef calves.
4. • Cattle fed diets containing extruded and expelled soybean meal had increased average daily gain and may offer an alternative to diets containing distillers grains as a primary source of protein.
5. • Cattle fed tylosin and monensin had increased intestinal microbial richness and increased bile acids that are known to support gut health in the jejunum and cecum.
6. • Feeding protected lysine supplementation feedlot diets can allow producers to decreasing dietary crude protein that subsequently decreases nitrogen excretion without compromising maintaining animal growth.
7. • Sorghum sudangrass can replace corn silage in feedlot diets of farmer-feeder operations to reduce planting costs without impacting feedlot cattle performance.
8. • Beef × dairy calves diagnosed with lung consolidation at weaning have reduced ADG through 83 d of life and a long-term reduction in marbling at slaughter.
9. • Adding body weight as a quadratic factor in the beef cattle nutrient requirements (NASEM 2016) model equation can improve predictions of dry matter intake.
10. • A novel Water Evaluation System (WES) will facilitate modeling to optimize water use for cattle in semi-arid environments under instability scenarios.
11. • Steers supplemented with 100 ppm Zn for six weeks prior to trucking had improved feed intake pre- and post-transit, and better pre-trucking performance, reinforcing the role of mineral status in stress resilience.
12. • Dairy-beef steers with excessive liver Cu were more susceptible to respiratory disease.
13. • Cattle fed lubabagron fumarate (Experior) had greater hot carcass weights than those fed ractopamine or just implanted, but had lower marbling scores. Producers will need to learn to manage carcass quality to avoid discounts, but carcasses are still worth more because of superior final carcass weights.
14. • Feeding cattle to heavier end weights adds days on feed and increases lameness frequency which reduces growth rate in slatted confinement facilities.
15. • Feeding diets with greater fiber immediately prior to slaughter can reduce E. coli populations and aid in mitigating pathogen risk at slaughter facilities.
