About 6 weeks ago, I was at the local auction and a 380# black steer came through with the ring with 4 other steers. This one was limping some so they cut him out by himself. The owner was there and stated the calf was fine when he got to the barn. Long story short I bought him cheep brought him home and in a few days he seemed fine. A few days later he was hunched up and limping again but it passed as quick as it came. Yesterday morning I had to check the cows in the dark and he was there but that's about all I could say about him. This morning he's dead, belly swollen and back side prolapsed any ideas?
