[Quality of ecologically produced foods of animal origin].

The production of organic (ecological) food of animal origin is done in many ways and uses many different breeds. Therefore a real comparison with conventionally produced food is difficult. From the limited number of published data it appears, that the characteristics of quality of the products, the nutritional, hygienic, sensorial and technological factors, are not very different in both systems of production. In some factors organic food gets better marks, in others the conventionally produced food. The differences are in the production system (process quality) during lifetime of the animals.
