(26)Derogations from the general labelling requirements should be provided for in so far as the application of such requirements is not necessary to protect human or animal health or consumer interests and would unduly burden the producer or the feed business operators responsible for the labelling. On the basis of experience, such derogations should be provided for, in particular with respect to feed delivered by one farmer to another for use on his farm, for small quantities, for compound feed not containing more than three feed materials and for mixes of whole plant grains, seeds and fruits.
