This study explored the effect of increased feed intake during the late gestation on the reproductive performance of sows, and fecal score in sows and piglets. A total of 21 crossbred [Landrace × Yorkshire] multiparous sows were randomly distributed into three treatments with seven replicates per treatment. Treatments: CON, 2.4 kg/day; TRT1, 3.2 kg/day; TRT2 , 3.6 kg/day. Body weight and body condition score of sow in different stages were not altered (p > 0.05) due to extra feed in late gestation. A linearly higher (p < 0.05) difference in backfat thickness during farrowing was found in this study. Average daily feed intake was increased (p < 0.05) linearly with extra feed in this experiment. The weaning body weight of piglets was increased (p < 0.05) with extra feed in the sow. The fecal score of sows and their piglets was similar (p > 0.05) in different levels of feed intake. In conclusion, extra feed to gestation sow showed a beneficial effect on improving the weaning piglet's body weight. Although there is a small improvement in the body weight of weaning pigs of sow fed 3.6 kg feed/day in the late gestation period, it is unlikely to be profitable enough to justify the additional waste of feed.
