ABSTRACT
The analysis of the influence of products with organic and conventional crop on health status parameters of laboratory animals was the aim of studies provided by several authors over the last fifty years, who compared: development rate, fertility and reproductive ability of rats, mice, rabbits and hens. In nine out of thirteen analysed studies, organic fodder has been demonstrated to exert a positive influence on parameters of the health status of laboratory animals. All of the studies concerning mortality rate of the young animals indicated the lower stillborn level in animals fed with organic fodder in comparison to those fed conventionally. Therefore it is possible to support a hypothesis that fodder obtained from organic produce may have a beneficial effect on animal health status, especially in relation to reproduction performance, pregnancy and immune system. It has to be emphasized that already conducted studies are not sufficient to fully confirm hypothesis described above and further and thorough studies are needed in this scope. The analysis of previous research and its results is essential to determine the scope and fields that need further investigation.
