Got a 3 year old. Calved 12 days ago. Everything went fine as far as I know. Milking good and cow and calf seemed great. Today out of the blue the cow has bloody discharge, not a ton but very noticeable almost like she retained some afterbirth. She is also very lame in her right rear leg. Are these symptoms related in any way? Will discuss with the vet tomorrow as well as try and get her caught.
