Livestock come into contact with contaminants of interest, in particular through contaminated feed. However, it is evident that in addition to the direct entry of contaminants, they can take up partially converted, degraded or bound substances in various more or less stable forms. Contaminated crop production may contain a different representation and concentration of nutritionally important substances compared to production that was not in contact with contaminants.
Within this activity, the response of selected animal species to the feed dose prepared from modified plant production is monitored. Recipes are designed and experimental feed mixtures are produced using the Optimix program.
For a comprehensive assessment of the nutritional value of prepared feed mixtures and bulky feeds, the determination of dry matter and ash, nitrogenous substances, coarse and detergent fibre, digestible organic matter and digestible fibre by in vitro method, crude fat content, digestible amino acids and amino acids, protein fractions, the effect of extrusion on feed quality of wheat and starch content will be carried out.
Rats are used for experiments as model organisms, together with poultry, rabbits, pigs and cattle. Feed contaminants are believed to specifically affect health and animal behaviour. They will reduce performance parameters and affect the quality of animal products.
