Loss of appetite for three days in a cow with no fever and normal dung and urine often points to indigestion, rumen slowdown, mouth pain, or a feed change problem. First, check her mouth for sores, broken teeth, or bad smell. Then offer only soft green fodder, clean water, and a little mineral mixture. Keep her walking slowly for a short while if she is not weak. Do not force-feed. If the belly is tight, she is chewing less, or she starts looking dull, get her examined the same day because rumen trouble can turn serious fast. Treating this now is much cheaper than losing milk and body condition. Consult a veterinarian before administering any medicine or treatment.
