Hefyd, mae’r data’n dangos bod 94.6 y cant o fuchesi wedi bod yn rhydd o TB yng Nghymru yn ystod chwarter cyntaf 2016. Golyga hynny fod dros 200 yn llai o fuchesi o dan gyfyngiadau oherwydd TB o’i gymharu â thair blynedd yn ôl.
The data also shows 94.6 per cent of herds in Wales were TB free during the first quarter of 2016, which means over 200 less herds were under restrictions because of a TB incident compared to three years ago.
