Experior, a feed additive by Elanco Animal Health, was FDA-approved in 2018 to reduce ammonia emissions from cattle in the final 14-91 days before slaughter. It works as a beta-agonist and beta-antagonist, improving metabolic efficiency and enabling longer feeding durations compared to similar products.
Performance and Carcass Quality
Studies show that feeding Experior increases average daily gain (ADG), feed efficiency, carcass weight, dressing percentage, and ribeye area in cattle. However, it reduces backfat and marbling scores, potentially lowering USDA quality grades. The reduction in marbling is attributed to a dilution effect caused by increased ribeye size relative to marbling contribution.
Research Findings
Research comparing different doses, durations, and withdrawal times highlights Experior’s ability to enhance muscle growth while reducing fat deposition. Longer feeding durations result in greater live weights, carcass yields, and ribeye areas, with consistent reductions in marbling scores.
Studies also compare Experior to other beta-agonists like Optaflexx, finding similar improvements in ADG and carcass traits but varying impacts based on feeding durations.
Considerations for Use
Farmers must sign user agreements with Elanco to ensure responsible Experior usage. These agreements specify doses and durations, with a recommended four-day withdrawal period before slaughter. Ongoing research seeks to understand interactions with implants and dietary protein levels.
Future Insights
While Experior shows promise for improving feedlot efficiency and reducing emissions, its impact on carcass quality remains a challenge. Continued research will explore optimal usage strategies to balance performance and quality.
Experior highlights the intersection of sustainability and productivity, paving the way for innovations in cattle feeding practices.
