So I have a jersey cow breed about 2-3wks old bottle fed 3 times daily and since we received her she has had diarrhea I have given her one bottle in the morning of milk one of electrolyte supplement in the afternoon and one bottle at night for one week started her on antibiotics about 4 days ago she was doing better so I've been giving her milk now 3 times daily and she was fine until yesterday where she became very liturgic has been laying down and will not even come to eat I noticed a red lump on her backside area today diarrhea has continued and I'm worried cause she would finish her night feeding today she left 1/4 of the milk and refused to suckle any answers on what I should do
