The Claim
Supplementing feedlot steers with ractopamine hydrochloride (300 mg/day) or lubabegron (36 mg/day) for 35 days during summer results in no significant difference in mobility scores compared to untreated controls, with at least 89% of cattle in all groups exhibiting normal mobility, indicating no increased risk of lameness or gait impairment under these conditions.
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 ractopamine hydrochloride or lubabegron for 35 days during summer, their mobility scores do not change significantly, and at least 89% of all cattle maintain normal gait regardless of treatment.
See the scientific wording
Supplementing feedlot steers with ractopamine hydrochloride (300 mg/day) or lubabegron (36 mg/day) for 35 days during summer has no significant effect on mobility scores, with ≥89% of cattle exhibiting normal mobility across all treatment groups, indicating no increased risk of lameness or gait impairment under these conditions.
The supplement activates receptors on muscle and fat cells, causing the body to build more muscle and store less fat without affecting how the nerves control movement or how the legs function, so the cattle walk normally even as they grow faster.
What the research says
1 studyCattle given these supplements walked just as normally as those not given them — no more limping or trouble moving, even though they grew bigger and faster.
