Mae’r CPH yn allweddol ar gyfer nodi ac olrhain lleoliad gwartheg, defaid, geifr a moch pe bai achosion o glefyd. Bellach, caiff parseli tir o fewn CPH eu mapio a bydd hynny’n sicrhau bod gan Lywodraeth Cymru a’r Asiantaeth Iechyd Anifeiliaid a Phlanhigion (APHA) gofnod gwell o’r daliad. Bydd hyn yn helpu i atal clefydau ac yn cynorthwyo gyda mesurau i reoli achosion o glefyd, a hynny o fudd i geidwaid a’r diwydiant da byw yn ei gyfanrwydd.
The County Parish Holding (CPH) identifier is key in identifying and tracing the location of cattle, sheep, goats and pigs should there be a disease outbreak.  Land parcels within a CPH will now be mapped, providing the Welsh Government and the Animal and Plant Health Agency (APHA) with an improved record of a holding. This will help disease prevention and outbreak control measures, benefiting keepers and the livestock industry as a whole.
