Pan adawodd y DU yr UE, cyhoeddodd legislation.gov.uk ddeddfwriaeth yr UE a gyhoeddwyd gan yr UE hyd at ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.). Ar legislation.gov.uk, mae'r eitemau hyn o ddeddfwriaeth yn cael eu diweddaru'n gyson ag unrhyw ddiwygiadau a wnaed gan y DU ers hynny.
Mae legislation.gov.uk yn cyhoeddi fersiwn y DU. Mae EUR-Lex yn cyhoeddi fersiwn yr UE. Mae Archif Gwe Ymadael â’r UE yn rhoi cipolwg ar fersiwn EUR-Lex o ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.).
Cyhoeddir Cyfarwyddebau’r UE ar y wefan hon i gynorthwyo croesgyfeirio o ddeddfwriaeth y DU. Ers diwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.) nid oes unrhyw ddiwygiadau wedi'u cymhwyso i'r fersiwn hon.
If a single animal in an officially enzootic-bovine-leukosis-free herd has reacted positively to one of the tests referred to in Chapter II, or where infection is otherwise suspected in one animal in a herd:
the animal which has reacted positively, and, in the case of a cow, any calf it may have produced, must have left the herd for slaughter under the supervision of the veterinary authorities;
all animals in the herd more than 12 months old have reacted negatively to two serological tests (at least 4 months and less than 12 months apart) carried out in accordance with Chapter II three months at least after removal of the positive animal and any possible progeny thereof;
an epidemiological inquiry has been conducted with negative results and the herds linked epidemiologically to the infected herd have been subjected to the measures laid down in (ii).
However, the competent authority may grant a derogation from the obligation to slaughter the calf of an infected cow where it was separated from its mother immediately after calving. In this case, the calf must be made subject to the requirements provided for in 2(iii).
Where more than one animal from an officially enzootic-bovine-leukosis-free herd has reacted positively to one of the tests referred to in Chapter II, or where infection has otherwise been suspected in more than one animal in a herd:
any animals which have reacted positively and, in the case of cows, their calves, must be removed for slaughter under the supervision of the veterinary authorities;
all animals in the herd aged over 12 months must react negatively to two tests carried out in accordance with Chapter II at an interval of at least four months and no more than 12 months;
all other animals in the herd must, after identification, remain on the holding until they are aged over 24 months and have been tested in accordance with Chapter II after reaching that age, except that the competent authority may permit such animals to go directly for slaughter under official supervision;
an epidemiological inquiry has been conducted with negative results and any herd linked epidemiologically to the infected herd has been subjected to the measures laid down in (ii).
However, the competent authority may grant a derogation from the obligation to slaughter the calf of an infected cow where it was separated from its mother immediately after calving. In this case, the calf must be made subject to the requirements provided for in 2(iii).] ]
