Formålet er at forlænge gyldighedsperioden for beslutning 90/218/EØF, ifølge hvilken medlems­staterne indtil den 31. december 1990 fik forbud mod at tillade, at malkekøer på deres område på nogen måde indgives bovin somatotropin, med tolv måneder.
Extends by 12 months the period of validity of Decision 90/218/EEC which pro­hibited, until 31 December 1990, the admi­nistration by the Member States of bovine somatotrophin on their territory by any means whatsoever to dairy cows, as the various effects of new substances such as bovine somatotrophin are not yet sufficien­tly clear and in this respect a necessary period should be provided for in-depth stu­dies to be made.
