(2)  In the case of additives referred to in Part II of Annex C to Directive 70/524, which includes micro-organisms, provisional authorisation of a new use of an additive already authorised may be given if the conditions laid down in that Directive are satisfied, and if it is reason- able to assume, in view of the available results, that when used in animal nutrition it has one of the effects referred to in Article 2(a) of that Directive. Such provi- sional authorisation may be given for a period not exceeding four years in the case of additives referred to in Part II of Annex C to that Directive. (3)  The use of the micro-organism preparation of Saccharo- myces cerevisiae (MUCL 39885) has been provisionally authorised, for the first time, for piglets and cattle for fattening by Commission Regulation (EC) No 1411/ 1999 (). (4)  New data were submitted in support of an application to extend the authorisation of this additive to dairy cows.
