I have a heifer that calved the 10th of January. No problems. Until this morning. She's off feed and standing away from the group. There is some bloat evident. Took her to the vet. She is impacted. We put a gallon of mineral oil in her orally and a couple gallons of warm water. He gives her a 50-50 chance. Bummer. It's been so cold, I think she probably didn't drink water like she should have. Does anybody know how long the mineral oil takes to work through her, provided it can? Any suggestions? I've walked her for a long time this afternoon, then let my border collie aggravate her. I don't want to lose her if I can possibly do something else. Surgery is possible but cost prohibitive.
