Abstract: With advances in genetic improvement in swines, it is important to adapt nutritional programs to the genetic potential and production capacity of sows, in order to guarantee better performance and productivity of piglets born. In the nutritional management of the pregnant female, adequate development of the placenta and umbilical cord should be considered to ensure nutrient and oxygen supply for fetal development. The increase in the number of fetuses in the uterus leads to an increase in competition of oxygen and nutrients by the fetuses leading to the birth of smaller and weaker piglets that are characteristic signs of retarded intrauterine growth. When there is no adequate development, piglets with low weight birth present limited performance throughout the production cycle, necessitating strategies that reduce the frequency of low birth weight piglets. Positive results have been achieved with supplementation of the feed gestation, increasing embryo survival, nutrient distribution, fetal weight and consequently improving the postnatal performance of the litter. The effects of the nutrition of pregnant sows on fetal development are highlighted in the present review.
