Sixty-nine crossbred gilts were utilized, over three consecutive parities, to evaluate the effects of increasing the feed intake in late gestation and lipid supplementation of maternal diets during lactation on sow and litter performance. In a complete randomized design, within a 2 x 2 factorial, all sows were fed 2.0 kg/day of a control corn-soybean meal diet (CS) with 3203 Kcal ME/kg from breeding to day 105 of gestation. From this day until parturition, half of the sows continued to receive 2.0 kg/day of CS diet while the others were fed same diet ad libitum. Following parturition and throughout lactation, sows from each gestation group were fed ad libitum either the control diet (CS) or a corn-soybean meal diet supplemented with 5% soybean oil (CSO) that provided 3400 KCal ME/kg. A total of 72 piglets divided equally between treatment and parity were slaughtered, 36 at birth and 36 at 48 hours later to determine the effects on neonatal energy reserves. Sows fed ad libitum in late gestation consumed 4.72 kg/day in that period. This higher (P<0.0001) nutrient intake, compared to 2.0 kg/day, was utilized to increase maternal weight gain (P<0.0001) rather than increase liver glycogen and carcass fat of piglets (P>0.10). Birth weight, litter size and survival were not affected (P>0.10). In addition, sows fed ad libitum lost more weight (P<0.0001) during lactation and had lower milk yield (P<0.03) than limit-fed sows. Despite the variations in sow weight, the weaning to estrus interval was not altered by dietary...
