The Claim
Administering lubabegron fumarate (Experior) to feedlot steers during the final 56 days on feed, with dosing 14 days before harvest, increases slice shear force by 20.1% compared to other timing regimens, indicating reduced meat tenderness.
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 given lubabegron fumarate 14 days before slaughter during the last 56 days of feeding, their meat becomes 20.1% tougher as measured by slice shear force, compared to other dosing schedules.
See the scientific wording
Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed increases slice shear force by 20.1% when administered 14 days before harvest, indicating reduced meat tenderness, while other timing regimens show no significant effect.
The drug causes muscle fibers to grow larger and pack more tightly, while also making the connective tissue between them stiffer. This makes the meat harder to cut when sliced.
What the research says
1 studyWhen cows were given this drug 14 days before being slaughtered, their beef turned out tougher when sliced — exactly as the claim says. Other times of giving the drug didn’t make the meat tougher.
