Insufficient knowledge and not enough rational livestock nutrition skills generate high costs of animal
production. The nutritional mistakes limit the exploitation of genetic potential of animals, affect animal health and performance negatively what leads to considerable financial losses. Moreover,
undigested nutrients of animal diets present the risk for environmental contamination. Therefore, there is a need to transfer skills and knowledge (know-how) on the new animal feeding systems and feed production with particular emphasis on the financial, animal physiology and environmental protection issues.
