1. Aids for investment in pig production shall be prohibited except for those granted for that volume of investments necessary to attain 550 pig places per farm.
The Commission may permit a Member State to adjust the limit in the first subparagraph in the context of a farm development plan in specific cases where 550 pig places will not provide a comparable earned income for 1 75 man-work units. However, even in such cases no aid may be granted for that part of the investment which brings the number of pig places to more than 1 000.
2. The detailed rules of application of this Article shall be adopted in accordance with the procedure laid down in Article 18 of Directive 72/159/EEC.
