Tracing the Domestic Pig

The appearance of the domestic pig today is shaped mainly by the economic expectations of us, humans. Todays pig has superior reproductive, fattening, and carcass traits compared to its ancient ancestors. This could not be achieved without the highly effective support of scientific research aimed at revealing the genetic basis underlying the important economic traits of pigs and the involvement of novel technologies in phenotyping these animals, both in vivo and post-mortem. Yet the research is spreading beyond the biological issues connected to the production of pigs and their products. The latest developments in computer science and informatics technology enable us to collect and store information from all stages in the production of food, leading back to its origin. Questions about the breed, the way the pigs were raised, how were they managed, and how they were processed into a wide palette of products can be answered by the use of methodologies developed by data scientists and those from the fields of different omics. All this information can be passed along the chain to consumers in a repeatable manner. The producers can use these data to manage such complex issues as meat or product quality. And this closes the circle. Tracing the domestic pig is an attempt to present the current knowledge about this valuable animalits origin, composition, and the food that it gives usand to predict or foresee what can happen to this species in the time to come.
