There is a substantial amount of evidence to support the concept, that animals are capable of choosing a balanced diet. This capability is used in food preference tests with laboratory animals. So far it has been postulated, that for animals to be able to choose, at least one of the offered foods has to be nutritionally unbalanced, otherwise there would be no benefit in choosing (Forbes and Kyriazaks 1995). But in organic quality research food preference tests with laboratory rats have shown, that even in cases of comparable nutritional value significant preferences took place, when the test products originated from different growing systems. Examples are comparative studies with wheat, carrots, beet root, celeriac and apples of organic vs... |

In the present paper the feeding experiment with laboratory rats, conducted at the Ludwig Boltzmann Institute for Biological Agriculture from 1987-1989 is described in more detail to show the advantages, but also the difficulties of the method (Velimirov et al. 1992). Two groups of rats (Long Evans strain), each consisting of 20 pairs, were fed with products from organic resp. conventional growing systems. After chemical analyses of all products, vitamins, minerals and trace elements were added if needed to provide nutritionally balanced diets. With 2 harvests 3 generations (6 litters) were investigated. In the first litters significantly fewer offspring were born dead or died within the first week of their lives. The survival rate until weaning time at... |
