One of the main causes of death in newborn piglets is the low level of energy reserves to maintain their body temperature, which can lead to hypothermia and, subsequently, death. Thus, the objective of this study was to evaluate the effect of soybean oil supplementation to sows in the first three days after farrowing to save piglet fat reserves through the higher nutritional intake of sow milk. In total, 604.5, 750, 1000, 1250 and 1500 g of soybean oil were provided for each sow during the three days of supplementation. A total of 60 sows were evaluated per treatment, distributed in a random block design, supplemented in the first three days after farrowing with soybean oil added on top of the feed at the time of feeding. Performance and reproductive data and milk samples were collected from the sows to determine fat levels. Piglets were evaluated for fall-back rate and survival. There was no significant effect of soybean oil supplementation on any of the parameters evaluated for both sows and their milk. Therefore, soybean oil supplementation for sows in the first three days after farrowing does not influence performance parameters, reproduction and milk fat of the sows and mortality and fall-back rate of the piglets.
