The core intention to undertake this experiment for a period of 21 days is to evaluate the effect of salicylic acid (SA) supplemented diet on the performance and blood metabolites of sows and their litters. Sows weighing 208.5± 18.34kg and their neonates were used. From day 114 of gestation to 21<sup>st</sup> day of lactation(weaning), ten multiparous sows (n=5/ treatment) (Landrace x Yorkshire) were assigned randomly into one of two treatments: CON (basal diet) and TRT [CON+ 0.05% salicylic acid (SA)]. There was no significant difference in the body weight, backfat thickness, backfat loss, and body condition score in SA treated sows compared to sows fed CON diet. However, the body weight of sow was dramatically reduced by average of 16kg from farrowing to weaning time. The dietary inclusion of SA in sow diet slightly improved the survival rate (<italic>p</italic>=0.065) and showed a higher body weight (<italic>p</italic>= 0.009) in piglet. However, there was no significant difference on RBC, Fe, Hematocrit, and Hb concentrations between CON and TRT sows’ groups, but the total Iron binding capacity (TIBC) was significantly reduced in sows from TRT group compared with CON group from the beginning to weaning. The outcome of this trial shows that dietary addition of SA on sow diet from early lactation could increased the birth weight and TIBC of neonates at the end of the trial.
