Lamb-a-Year: Sustaining Sheep Industry Excellence 

The Lamb-a-Year program offers students practical learning experiences in managing and marketing lambs, covering aspects like nutritional management, animal health, record keeping, and market dynamics. Each year, numerous lambs are generously donated by regional producers, to generate funds for further programming. The program seamlessly integrates research, teaching, and extension, providing hands-on opportunities aligned with the land grant mission. Producers benefit from personalized performance reports with detailed graphs, enhancing their understanding of lamb performance across breeds and sexes. This enduring initiative sustains industry excellence and innovation, benefiting students, sheep producers, and the university by fostering practical skills and industry insights.
