The Claim
Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed increases hot carcass weight by 14–37 kg compared to a no-beta-agonist control group, with no significant difference in hot carcass weight compared to ractopamine hydrochloride.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When feedlot steers are fed lubabegron fumarate for the last 56 days before slaughter, their carcass weight increases by 14 to 37 kilograms compared to steers not given any beta-agonist, and this increase is not different from the weight gain seen with ractopamine hydrochloride.
See the scientific wording
Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed increases hot carcass weight by 14–37 kg compared to a no-beta-agonist control group, with no significant difference compared to ractopamine hydrochloride, indicating enhanced carcass yield.
The drug binds to specific receptors on muscle cells, which turns on a signal inside the cell that tells the muscle to build more protein and stop breaking down protein. This makes the muscle bigger and heavier, which increases the weight of the carcass after slaughter.
What the research says
1 studyThe study found that giving this drug to cattle for the last 56 days before slaughter made their carcasses 14 to 37 kg heavier, just like the claim said — and it worked just as well as another similar drug.
