Last night while doing chores I noticed one of my cows was laying really strange and in an awkward position so I went over to try and help her, but she wouldn't get up because of where she was laying. So we got the skid steer and harnessed her so we could move her so she could get up and after about 30 minutes she did, but was very weak and timid. Usually she is high strung and when I go by her calf she is there to protect it. This morning I went out and her eyes were sunk into her head and she seems very weak when moving. We gave her a shot of Banamine just to try and make her feel better. I can't really think of whats going on. She had a calf and cleaned on the 10th and has been on the same hay as all the other cows. What do you guys think!? Thanks for the help.
