The Claim
Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed has no significant effect on daily dry matter intake, morbidity, mortality, or liver abscess rates compared to feedlot steers not receiving a beta-agonist or ractopamine.
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 for the last 56 days before slaughter, their daily feed intake, sickness rates, death rates, and liver abscess rates are the same as those of steers not given any beta-agonist or ractopamine.
See the scientific wording
Feeding lubabegron fumarate (Experior) to feedlot steers for the final 56 days on feed does not significantly affect daily dry matter intake, morbidity, mortality, or liver abscess rates compared to no beta-agonist or ractopamine controls, indicating no adverse impact on animal health or feed efficiency.
Lubabegron activates receptors in muscle that cause the body to build more lean tissue and hold onto more protein from feed, so less nitrogen is wasted in urine. This lowers the amount of ammonia produced by bacteria in manure, but it does not change how much the animal eats, how often it gets sick, or how many die, because the drug does not affect the digestive system, immune response, or liver function.
What the research says
1 studyGiving Experior to cattle didn’t make them eat more or less, get sick more, or die more than cattle not given the drug. It just helped them grow bigger and produce less smell, with no signs of harm.
