For these animals the number programmed on the chip of an EID tag will be the same number printed on the tag or pair of tags and would be an official form of identification.
Ar gyfer yr anifeiliaid hyn, bydd y rhif a raglennir ar sglodyn tag EID yr un rhif wedi'i argraffu ar y tag neu bâr o dagiau a byddai'n ffurf swyddogol o adnabod.
