Food produced in ecological agriculture becomes popular more and more.
In the interest of consumers (to protect against deception) and of pr
oducers (to contrast with conventionally produced food) it is necessar
y to define the conditions and circumstances when products can be decl
ared as ecological. Up to now definitions of housing and feeding anima
ls in organic agriculture only are set up by private organizations and
associations, but in the future we will have a direction of the Europ
ean community (Nr. 2092/91 EWG), extended by directives and restrictio
ns focussed on animal husbandry and feeding. Aim of this contribution
is to give information on special restrictions on feeds and feeding of
food producing animals in organic agriculture (preconditions in the c
ase that labelling as,,ecologically produced'' is intended). Conventio
nally produced feed-stuffs are restricted, common complete diets and s
ome special feed additives (for example growth promoters) are not allo
wed. Feeding according to species specific requirements (herbivorous a
nimals) as well as according to age and development (for example minim
um duration of suckling periods) is intended. On the other hand there
is a conscious renunciation of maximizing animals' performance (and pl
ant yields). Consequences, risks and conflicts of different aims in fe
eding in accordance with ideas of organic agriculture are discussed. V
arious efforts at sustainability of conventional agriculture are influ
enced markedly by ideas and concepts established in organic agricultur
e primarily.
