The improvement in the nutrient level of the sow should not only cover the quantity, but also the quality of the essential nutrients needed for the embryonic development of the litter and the immune integrity of the young piglets. Tests carried out conclude that the diets used in sows have low levels of omega-3 fatty acids (EPA and DHA). The initial foetal development is the phase of higher omega-3 requirements and the time when nutrients are essential for some tissue development (brain, eyes, ente-rocytes). At this time a shortfall puts embryo viability at risk.
