Lasalocid or monensin (600 mg per 1000 lb body weight daily) was tested
on cattle bloating on high grain diets. Bloat was reduced 92% by Lasalocid and
64% by monensin. When fed throughout the finishing period, lasalocid at 300 mg
per 1000 lb body weight effectively prevented bloat from developing. However,
600 mg was required to control bloat in cattle that were already bloating.
