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 21st 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% 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 the CON diet. However, the bodyweight of sow was dramatically reduced by an average of 16kg from farrowing to weaning time. The dietary inclusion of SA in the sow diet slightly improved the survival rate ( = 0.065) and showed a higher body weight ( = 0.009) in piglets. However, there was no significant difference in red blood cell, Fe, Hematocrit, and Hb concentrations between CON and TRT sows' groups, but the total iron-binding capacity (TIBC) was significantly reduced in sows from the TRT group compared with the CON group from the beginning to weaning. The outcome of this trial shows that dietary addition of SA on sows diet from early lactation could increase the birth weight and TIBC of neonates at the end of the trial.
进行为期21天该实验的核心目的是评估补充水杨酸（SA）的日粮对母猪及其仔猪生产性能和血液代谢物的影响。选用体重为208.5±18.34kg的母猪及其新生仔猪。从妊娠第114天至泌乳第21天（断奶），将10头经产母猪（n = 5/处理组）（长白猪×大白猪）随机分为两种处理之一：对照组（基础日粮）和处理组（对照组日粮+0.05% SA）。与饲喂对照日粮的母猪相比，SA处理的母猪在体重、背膘厚度、背膘损失和体况评分方面没有显著差异。然而，从产仔到断奶期间，母猪体重平均显著降低了16kg。在母猪日粮中添加SA略微提高了仔猪的存活率（P = 0.065），且仔猪体重更高（P = 0.009）。然而，对照组和处理组母猪之间的红细胞、铁、血细胞比容和血红蛋白浓度没有显著差异，但从开始到断奶，处理组母猪的总铁结合能力（TIBC）与对照组相比显著降低。该试验结果表明，从泌乳早期开始在母猪日粮中添加SA可提高试验结束时新生仔猪的出生体重和TIBC。
