No
This looks like a digestive or feeding problem, not a fever illness. First check the fodder. If the green fodder is old, mouldy, dusty, or the concentrate was changed suddenly, stop that feed today and give only clean green fodder, good dry roughage, and plenty of fresh water. Keep her in a calm place and watch if she is chewing cud, passing dung normally, and drinking well. If dung is hard, very dry, or very little, give more roughage and water. If she is off feed for a full week, the common possibilities are rumen upset, worm burden, mouth pain, or a hidden liver or stomach problem. If she is still eating less tomorrow, or if milk drops, dung stops, bloat appears, or she becomes dull, book a Pashu Vet on Pashushala for a physical check. Treating this early protects milk income and prevents a small feed issue from becoming a bigger loss.
