Hi I have a 5 week old Brown Swiss Steer calf that i was about to wean, Then this morning, I was giving him his bottle and he pressed his neck down on to the fence Hard and he started breathing hard and milk started coming out of his nose and he was sucking on the bottle nipple so hard it took me a little bit to get the bottle out of his mouth so he'd stop sucking on the bottle. And he Never coughed after inhaling the milk, I have had calves get milk in the wrong tube before and they always coughed several times and we're fine. No meds necessary. Not Him, he didn't cough ,he walked around alternating between putting his nose in the air and putting his nose almost on the ground and making a terrible mooing noise like a dying calf makes. I had to be at an appointment so I left thinking he was going to be dead when I got back. When I got back it he was still alive,just laying down breathing hard, and he won't get up. It's to late to call my vet tonight and I was wondering what I can do for him? If anything?
