This is our jerseys second lactation, and she just calved this evening. Healthy little bull calf that is doing good. Mabel on the other hand is having problems I think. She will moo or bellow and then start panting with her tongue out. It's cool tonight so I don't think it's because she is hot. Her ears are warm, but she has a swelling on her right back leg high up next to the udder. It feels like muscle knots. Any ideas what the panting could be from? I do have a large tube of calcium gel available just in case.
