Animal food has to incorporate multiple objectives, ie. it should provide good animal health, good production and reproductive performance, reduce pollution of the environ- ment as well as have the impact on food of animal origin, by supplying it, in addition to basic nutrients, with certain useful substances that can act preventively on the occurrence of var- ious diseases in humans in modern living conditions. This complex task implies the appli- cation of scientific knowledge concerning biotechnology in the field of animal feed produc- tion, and also includes the use of specific nutrients that are the result of the latest develop- ments in specific disciplines such as molecular biology and genetic engineering. As a result of researches in these areas there were created some varieties of cereals and legumes with improved nutritional properties. On the other hand, obtaining a safe food of animal or- igin product imposes the use of substances of natural origin (such as probiotics, prebiot- ics, phytobiotics, enzymes, chelating forms ..), which provide better digestibility and more complete utilization of certain nutrients from the feedstuff. In this way, the quantity of undi- gested substances are significantly reduced as well as soil and the atmosphere pollution. The use of specific additives in animal nutrition resulting from biotechnological re- search is most frequent when a problem concerning certain level of production or animal health has to be overcome. This implies a group of non-nutritional ingredients which are aimed to regulate the digestive tract microflora, pH, weight gain, as well as to modify met- abolic processes etc.
