Environment and weather may have a significant impact on feedlot cattle growth. Most U.S. feedlot cattle are finished/fed in open-mound, dirt lots. Historic closeout data conclude that cattle performance has been optimal when finishing cattle in well groomed, dry, dirt mound lots. However, weather challenges including excessive heat, cold, or moisture conditions negatively impact cattle performance. Past attempts to provide shelter for finishing feedlot cattle with buildings/sheds have often yielded subpar finishing cattle growth expectations when compared to well-groomed dirt mounds. Improved cattle housing designs including building ventilation and flooring types are being utilized in many Northern Plains and Midwest cattle operations during the last decade. This symposium will address current designs, management issues, economic considerations and future improvement challenges for finishing cattle housing systems. Performance and economics comparing various cattle breeds and varied in-weights throughout finishing period in differing cattle facilities will be evaluated. Comparison of expected and realized performance of finishing cattle when housed in bedded barns, conventional scrape yards with sheds and cattle comfort finishing shelters will be reviewed.
