Fel nad oes byth dwy fferm union yr un fath, nid oes dau achos o TB union yr un fath,ac mae lefelau TB yn amrywio o ardal i ardal yng Nghymru.Felly, mae'n hanfodol bod ffermwyr yn gweithio'n glos gyda'u milfeddyg i amddiffyn eu buchesi a chadw TB allan, yn ogystal ag i ddelio â'r clefyd os bydd yn taro.
Just as no two farms are the same, no two TB breakdowns are identical, and we do see variations in TB levels in different parts of Wales. Therefore, farmers working closely with their vet is crucial to both protect herds and keep TB out, as well as tackling the disease if it does occur.
