The animal research gives more attention, for more than twenty years, to the improvement of food quality, because this aspect plays an important role in the consumer choice. In this paper are browsed the principal foods of animal origin (milk, meat and eggs), paying attention on the actual genetic and physiologic knowledge, which influence the quality characteristic. Particularly, we examined the role of Quantitative Genetic in bovine and swine and the growing knowledge about animal genomes and individuation of QTL. Information on genomic regions that control QTL, allow to organize genetic improvement programs, using Markers Assisted Selection (MAS) and Markers Assisted Introgression (MAI). Moreover are reported the knowledge about metabolic processes that influence quality especially on lipid and protein component. About other productions are considered the physiology of eggs production and the genetic improvement of hens. Finally the qualitative aspects about poultry and rabbit meat and the actual genetic improvement strategy are reported.
