I found my Jersey lying down and not standing. She is alert and eating and drinking fine and she will move (somehow) after she poops. I gave her a bottle of cmpk drench and then tried to lift her with the tractor and she would just go back to the ground without trying to stand. She did calve Sept. 28th and has had 2 orphans on her and all were doing great until we got a slight cold snap and then this. The calves have all been with her since the first part of October. Would IV calcium , Asprin or B-12 be an option that would be of any smarts ? How long can she be on the ground before I need to consider ending the attempts to save a great nurse cow?
