Hi All. I have a heifer calf half beef quarter jersey quarter Holstein. She is 3 months old. I tried to take her off of milk at 2 months old, because she was eating 5 pounds of grain a day. And she bloated. Running her around got her going again and the bloat went away. Then I tried weaning her again at almost 3 months old after being on grain for 5 days she quit drinking water and bloated. I treated her with oil. Vet said to use Mineral Oil. She went back down after being bloated for 3 days. Fast forward to 5 days ago I took her off of milk again. Yesterday evening she bloated. I took her for a walk and she passed gas and looked normal. This morning she was slightly bloated. I gave her a bottle of milk, because once again she isn't drinking any water. I gave her electrolytes at noon, she's swelled up like a barrel. I gave her oil like the vet had me do last time. The vet said he thinks she has something wrong inside of her and she's going to be a chronic bloater. But neither him nor the other 2 people I have talked to about her understand why she bloats when she is taken off of milk?? They all agree that she should be bloating from the milk Not when she is taken off of the milk. I wonder if her rumen isn't developing like it should? The vet said it may be that her abumason isn't developed correctly.? She's pooping and peeing and she's eager to trot wherever I lead her on the halter. She looks like she swallowed a 55 gallon barrel.
