The development of a scientific area is greatly influenced by the level and efficiency of the related innova-tion activity. The purpose of this paper is to present some important innovative activities in swine nutrition from the past and present that contributed to the production of better quality pork. A further aim is to summarize briefly the innovation activities which can be expected in pig nutrition in the future. In the pre-sent paper, the following main topics are discussed: challenges of 21st century animal nutrition; evolution of the innovation in pig nutrition; innovation activities in energy- and protein (amino acid) metabolism stud-ies, in the fight against heat stress and in the determination of the molecular structure. Further discussed topics are animal nutrition and immunology, application of molecular nutrition findings in pig feeding, animal nutrition and gut microbiology, and pig nutrition based on genetic profile. The paper also predicts the possible innovation activities in the future. It was concluded that future innovation activity in pig nutri-tion research is carrying out in three directions: a) Research related to feed (new feed ingredients and feedstuffs); b) Development of new animal experimental and laboratory methods together with associated sciences; c) Development of new (biological, technical) concepts and principles
