The pig production sector faces great challenges in relation to guaranteeing its economic, social and environmental sustainability, in all three aspects the efficiency of production guaranteeing the welfare of the animals is a key element, and in particular it is the efficiency with which feed is used on farms, as on the one hand, feed costs can reach 70% of total costs and its consumption is closely linked to emissions from the farm. The consideration of all these elements in current pig production, from the perspective of nutrition and genetic improvement, is a reality for the sector, and also for research projects of applied interest that are being developed both nationally and internationally. The proposed conference aims, on the one hand, to present research activities applied to the disciplines of nutrition and genetic improvement are being carried out by IRTA with the aim of increasing the sustainability of the pig sector; and on the other, to offer the practical vision of the implementation of some of these developments by companies in the sector.
