In this presentation we to investigate different sow nutrition strategies with the final aim to improve piglets’ viability and performance. Salmon oil and vitamin D supplementation during gestation, and salmon oil supplementation and increasing energy density during lactation were studied in two different trials. Salmon oil and Vitamin D during gestation resulted in higher levels of Omega-3 fatty acids and Vitamin D in colostrum, milk and piglets’ tissue, but no evident improvement in piglets’ growth or performance was observed. While salmon oil during lactation resulted in a slight reduction of piglet per-weaning mortality.
