Please don't consider drenching your steer with Golden Flo.
Chances are you'll either kill him by getting the fat in his lungs, scar his esophagus, or disrupt rumen activity and set him back.
Non-therapeutic drenching is considered to be animal cruelty. The animal does not need it.
If the animal is not sick, leave them alone.
Add Golden Flo or similar product to their feed at the recommended level if you want more fat on the animal.
Good luck to you!
