I have a 5 month old angus bull who went down on me Friday evening. He tries to stand but just cant get up. I have been giving him 6cc of penicillin twice a day and 4cc of B12 twice a day. I also gave him a 3cc Ivomec shot Saturday night. He is eating and drinking well. All body fluids are normal. I hoist him up for about 5 hours a day and lay him down at night. He has very good strength in his back legs but will not put weight on his front. He will move them and stomp and I did get him to stand for about an hour 2 days ago. Any suggestions to what is wrong with him. He is the 4 one that has went down on me in a month.(Cyoties got to the other 3 before I could) He is a free rain grazer and the weather here has been extremely bad this year.
