It looks like a feed change upset the buffalo’s stomach. First, keep her on the same roughage and do not change feed suddenly for a day or two. Give clean water freely, offer soft green fodder in small amounts, and avoid too much concentrate, stale feed, or very wet fodder. If she is still eating, walking normally, and dung is not very loose, this usually settles with rest and steady feeding. If she stops eating, gets loose motion, bloating, fever, or milk drops sharply, then she needs a vet check the same day. Treating it early protects milk income and prevents a bigger loss later.
