Article 1 (1) of Regulation (EEC) No 3901/89 defines lambs fattened as heavy carcases as those which have been the subject, after weaning, of a declaration of stock sent for fattening in verifiable batches and have reached a minimum average weight of 25 kilograms following a minimum period of fattening of 45 days; whereas, however, the second subparagraph of that paragraph provides for a derogation with regard to weaning for lambs belonging to a limited number of meat breeds and raised in geographically well defined areas.
