I Have a 400 pound steer that was bloated pretty badly last Saturday Morning. Took calf to the vet and they drained the gas by sticking hose down the throat and then putting rumen stimulation back in the gut. Brought him home and put in the lot so i can watch him,everything has been fine till tonight and he is bloated back up. He is on long stem grass hay and water and thats it,no grain whatsoever.Any ideas or comments to try? Thanks.
