The Claim

Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed reduces calculated cumulative ammonia gas emissions by 5.6–13.6% per kilogram of body weight or hot carcass weight compared to no beta-agonist control, indicating improved nitrogen retention and reduced environmental impact from feedlot operations.

Cause and effect

In plain English

When feedlot steers are fed lubabegron fumarate during the last 56 days before slaughter, ammonia gas emissions per kilogram of body weight or carcass weight decrease by 5.6–13.6% compared to steers not receiving any beta-agonist, resulting in lower environmental emissions from feedlot operations.

See the scientific wording

Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed reduces calculated cumulative ammonia gas emissions by 5.6–13.6% per kilogram of body weight or hot carcass weight compared to no beta-agonist control, indicating improved nitrogen retention and reduced environmental impact from feedlot operations.

Why this might work

The drug binds to receptors on muscle cells, causing the muscles to grow more protein and store more nitrogen from feed. This leaves less nitrogen in the urine, so less of it turns into ammonia gas in the manure.

    When cattle are given this drug called Experior for the last 56 days before slaughter, they produce less ammonia smell from their manure—by about 6% to 14% per pound of body weight—compared to cattle not given the drug.
